...What is the differnce between earth science and biology? earth science is rocks minerals and the study of the earthen sphere and all that make it. biology is about organic compounds and anything living (bio) that has home on it. Why is it important to study Earth Science? Because we find out about the earth and its environment from the books. How the environment affected the people on earth and what precautions should we adopt so we can get along with it. It also is important because you get to know more about your earth. The simple answer is, because it's awesome. Otherwise, Earth Science is very important in understanding how our world works. It has many different applications, from oil and mining, to waterways and seas, to understanding Earth History, and to engineering and building, as well as many others. Because you want to know about the Earth? Or because you think that the qualification will help you to get the type of job that you want. SO we can make good predictions an be prepared what can happen in the future. One example of a bad prediction is 2012. 1st. the myians never predicted that. 2nd. My dad talked to a scientist about it and he said everyone that's saying different ways that other people said the world is going to end is fake. so we will know that earth science is literacy of critical importance to our nature.

...Earth Science In my personal observation if you truly want to learn about science visit this section. There are so many things to learn in his one section that is hard to explain. I will start off by talking about mineral. Minerals are substances that occur naturally in the earth, are formed by physical (not biological) methods, and have characteristic chemical composition, physical properties and crystalline structures (though not necessarily visible crystals). Classification of Minerals are antimonates, vanadium oxysalts, tungstates amd molybdates, silicates, phosphates, arsenates, and vanadates, sulfosalts, halides, sulfates and chromates sulfides, carbonates, borates, nitrates and iodates. An element is a substance made of only one kind of atom. Among the over one-hundred known elements only about twenty are found not combined with other elements. Rocks are composed of one or more minerals. While a mineral is the same throughout, a rock is a mix, and can vary from part to part. Minerals form a variety of crystals like monoclinic, tetragonal, triclinic, hexagonal, isometric, orthorhombic system. Types of meteorites stony meterorites are made mostly of silicated minerals such as olivine and pyroxene (most common). Stony-iron meteorites are made of about equal amounts of silicate minerals and metal (least common). Iron- metorites are made almost entirely of metal-iron, nickel and cobalt (heavy metal). Meteorites come from out in space. Most meteorite are stony and...

Date: Introduction Near-Earth Objects (NEOs) can be defined as heavenly bodies or solar system objects that have been pulled gently by the gravitational force of the Earth bringing them close to into orbits and the Earth’s neighborhood. These NEOs include Near-Earth comets, Near- Earth asteroids, meteoroids and a few solar-orbiting spacecraft huge enough to be trailed in space before hitting the Earth. The collision of the NEOs in the past has had a significant part in shaping the biological and geological history of the Earth. Near-Earth asteroids (NEA) have orbits that rest between 0.983 to 1.3 astronomical units from the sun (Shapiro, 1999). Due to this the Earth’s orbit cross with some NEA orbits posing a collision danger. By 2012 August there were 848 Near-Earth asteroids that were larger than 1km and 154 of those had were potential hazardous asteroids (PHAs).Comets are mostly composed of ice water with engrafted dust particles. They are formed on the outer system of the planet. The asteroids are mainly rocky and are formed in the warmer inner solar system between the orbits of Jupiter and Mars (Bally, Reipurth 2005). Scientific interest in asteroids and comets is due to their status because they have unchanged debris from the solar system formation dated back to up to 4.6 billion years...

...Lecture note 1 Earth Science is the study of the Earth and its neighbors in space the four basic areas of Earth science study are: geology, meteorology, oceanography and astronomy. Geology deals with the composition of Earth materials, Earth structures, and Earth processes. It is also concerned with the organisms of the planet and how the planet has changed over time. Geologists search for fuels and minerals, study natural hazards, and work to protect Earth's environment Meteorology is the study of the atmosphere and how processes in the atmosphere determine Earth's weather and climate Oceanography is the study of Earth's oceans - their composition, movement, organisms and processes. Astronomy is the study of the universe Lecture note 2. Earth in the Universe According to the Big Bang theory, the universe began about 13.7 billion years ago, when everything in the universe was squeezed into a very small volume, as described above. There was an enormous explosion—a big bang—which caused the universe to start expanding rapidly. All the matter and energy in the universe—and even space itself—came out of this explosion. some stars are actually grouped closely together in space. These small groups of stars are called star systems and larger groups of hundreds or thousands of stars are called star clusters. The biggest groups of stars are called galaxies. Galaxies are divided into three types according to shape: spiral galaxies, elliptical galaxies, and irregular galaxies ...

...frica’s East A Great Rift Valley: A Complex Rift System Journal Article Review Stephen Underwood, Instructor PHSC 210 Elements of Earth Science March 23, 2012 Introduction The East African Rift System (EARS) seems to be one of the most amazing geographic studies of the world. A rift can be defined as a split in the earth’s surface that becomes wider over time. In this case, the EARS has developed into two plates or branches, which have been named the Nubian Plate and the Somalian Plate. The two branches include a west branch, which consists of the African Great Lakes, and a nearly parallel east branch, which divides Kenya from north to south and enters Tanzania. Because the two branches have become so distinct, there is a common misconception that there is only a single rift in East Africa. However, geologists have discovered a series of rifts in Africa. Thus, the growing number of rifts has become of interest to many geologists and scientist. Brief Overview and Main Points In this article, James Wood and Alex Guth discuss the geographic and physical structure of the East African Rift System as well as the underlying causes of rift formation. The East African Rift (EAR) involves a fracture that has resulted in two branches-- a western branch, consisting of the East African Great Lakes, and an Eastern branch, dividing Kenya completely and entering Tanzania. The EAR has been grouped with other rifts, especially the Ethiopian rift, to form the East African Rift...

...be rubbed off easily. The color of the rock is mostly white, with hints of red and black sediments. There are no visible crystals either, but there are a vast amount of grains seen throughout the rock. Mainly due to my observations, I believe that my rock is of a sedimentary origin. I believe this because of several details I made that help justify my classification. First off, the rock's texture is clastic, as there are many visible fragments. I can also tell that the grains in the rock are very fine, due to the fact that I would have to use a microscope to distinguish them. Sediments chip and fall off easily when rubbed against any surface, which proves the sediments and grain size is very small. I narrowed my search down in the Earth Sciences References Tables (ESRT). Looking at the ESRT, on page 7, I found that there are two tables with Scheme for Sedimentary Rock Identification. One table was categorized with the texture "clastic", which had to be what I was searching for. I narrowed my results down even further by distinguishing the grain sizes in the rocks. Conglomerate had rounded fragments, with bigger grain sizes than I had noticed. I moved on to breccia, which had...

...Earth Science: Volcanoes Report by: Kenneth Ragragio What is Volcanoes? * Volcanoes are vents that allow lava, rock fragments and gases to escape from layers beneath the earth's surface. Learn how volcanoes form both on land and underwater and why they erupt. * Volcanoes are spectacular events and because of this, they have found their way into the plot of many Hollywood movies. While the movies have given most of us the vivid image of red-hot lava spewing out of the top of a towering volcano, they do not share the entire story of volcanoes Magma and Lava * So what exactly is a volcano? Well, it can be defined as a vent in the earth's crust through which lava, rock fragments, hot vapor and gases are ejected. In other words, a volcano is the earth's way of letting off a little steam. * The super-heated particles that eject out of a volcano come from deep below the earth's surface where temperatures can become so hot that rock actually melts. Magma is the term used to describe this hot molten rock from deep within the earth. * A volcano begins to form when magma, which is less dense than the rock it originated from, rises toward the earth's surface. This liquid rock collects in chambers called 'magma chambers,' where pressure builds due to expanding steam and gases associated with the magma. As pressure reaches a peak within these chambers, magma finds its way through a vent or fissure in the earth's surface, resulting in a volcanic eruption and the expulsion...

...[Type the company name] | Written Assignment 3 | Earth Science | | | | | Written Assignment 3 1. Describe the bathymetry of the ocean seafloor and how the features relate to plate tectonics. The term “bathymetry” originally referred to the ocean’s depth relative to sea level, although it has come to mean “submarine topography,” or the depths and shapes of underwater terrain. In the same way that topographic maps represent the three-dimensional features of overland terrain, bathymetric maps illustrate the land that lies underwater. The ocean has mountain ranges, volcanoes, trenches, canyons, and other structures. The oldest rocks on the ocean floor are 180 million years old. This is young compared with the oldest continental rocks, which date from 3.8 billion years ago. While the continental crust has been steadily accumulating throughout Earth’s history, it seems the oceanic crust is created and destroyed rather quickly. It is created at the mid-ocean ridges from hot material rising in the mantle, and then spreads away from the ridges, before eventually being recycled into the mantle at subduction zones. Continental crust is always less dense and more buoyant than oceanic crust, so where they meet, it is the oceanic crust that gives way, sinking (subducting) back into the mantle The boundaries of a tectonic plate may be divergent, convergent, or transform. At divergent boundaries, the crust is extended, thinned, and fractured by the upwelling...

...Geology 1210 Homework #6 #15 When and what sequence of events led to the origin of the Himalayas in Asia? During the late Cretaceous India’s plate and the Eurasian plate began to collide approximately 70 million years ago. The Indian plate destroyed a chain of volcanoes as it collided with southern Asia, near present day Tibet. As India’s landmass subducted into southern Asia during the Miocene, the Himalayan Orogeny was born from the continent to continent collision. This ended the ocean to continent subduction in that area. The exposed mountain rocks are limestones that were uplifted after the collision. Still currently, the Indian plate is moving northward into southern Asia, along a thrust fault, that allows the Himalayas to grow bigger still every year (at 5-6 mm a year). This area is seismically active, and earthquakes happen periodically. #16 Explain how plate interactions were responsible for the origin of the San Andreas Fault. The North American plate and its collision with the Pacific Farallon plate created the Pacific-Farallon ridge during the Eocene. This created two triple junctions, one at the where the Juan de Fuca (remnant of the Farallon) intersected the NA/Pacific plates along the northern Pacific coastline of NA, and another where the Cocos (remnant of the Farallon) intersected the two plates as well along the southern Pacific coastline of NA. The continued westward movement of the North American Plate over the Pacific Plate caused aforementioned triple...

How does insolation explain why the equator hotter than the poles? The sun shines on the equator 100% of the time. 4. What effect does tilting the Earth’s rotational axis have on the distribution of solar radiation (insolation)? It causes seasons. 5. Why it can be winter in the U.S. when it is summer in Australia? Because of the way the Earth tilts toward the sun. When it is summer in the US, it is winter in Australia. 6. At what latitude are direct rays hitting during each season in the U.S.? Spring Summer Fall Winter 0-23.5N 23.5N-0 0-23.5S 23.5S-0 7. What would happen to temperatures in Australia if Earth’s tilt angle increased during summer in the northern hemisphere and why?

...1) Describe the bathymetry of the ocean seafloor and how the features relate to plate tectonics. The bathymetry of the ocean floor is the shape of the ocean floor. On the ocean floor there are also anomalies, gravity and magnetism in different areas of the ocean. “We know these things because it has been mapped out using a process called sonar, Sound Navigation and Ranging. This is done by creating sound waves from a ship at the surface that bounce down off of the seafloor and then come back up. There have actually been a variety of techniques. One of the most important has been side scan sonar that is actually able to map to fine details of the shapes of the ocean seafloor.” (Wysession, teachingcompany.12.forumer.com; 2008) “Ocean bathymetry, to the people involved with early mapping, was a total surprise for a wide variety of reasons.” (Wysession, teachingcompany.12.forumer.com; 2008) “When you look at a lake you know that the deepest parts of that lake will be out away from the shore, perhaps on the very middle. The areas around the back are usually the shallowest. This is not the case in the ocean. In the ocean, the deepest places are the ocean trenches which are found at the edges of continents. It turned out that in the middle of the ocean there are mid-ocean ridges that formed this long continuous chains of mountains that are all connected. The mid-Atlantic ridge connects to the east Pacific rise, and the Indian ridge, and in all three principle oceans these represent...
