Falling stars aren't stars at all, they're actually tiny pieces of dust impacting the Earth's atmosphere and burning up. You might also have heard them called "shooting stars", but their scientific name is "meteors". Let's learn some more about falling stars. Space looks empty, but there's all kind of stuff out there: gas, dust and tiny rock and ice fragments. The tiny pieces of rock or ice are known as meteoroids. They could have been left over from the formation of the Solar System 4.6 billion

gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. This hurts many people, animals, and plants. Many cannot take the change, so they die. What is the greenhouse effect? The greenhouse effect is when the temperature rises because the sun’s heat and light is trapped in the earth’s atmosphere. This is like when heat is trapped in a car. On a very hot day, the car gets hotter when it is out

Heating of the earth exterior and atmosphere and influences patterns of precipitation the sun heats the air at the equator causing it to expand and rise. This warm moist air cools as it rises. Since cool air holds less water vapor than warm air the water carried by the rising air mass condenses and forms clouds which produce the heavy rain fall associated with the tropical environment. Eventually this equatorial air mass ceases to rise and spreads north and south. The high altitude air is dry since

(multicellular organisms). The current causes of ice ages remains a controversial topic, but is thought to be a number of factors which ocacionan this, changes in the Earth's atmosphere, position of continents, Milankovich astronomical cycles, variations in solar activity, volcanism , galactic cosmic radiation,. Changes in the Earth's atmosphere, it is believed

Outline the activities providing for the cycling of Earth materials (matter) in the Ecosphere. Explain the role of solar energy and its interrelationship. The Earth’s materials cannot be made or destroyed and the matter that is presently on Earth will never disappear nor will new matter be made. When thinking about matter, the most common idea is elements. These are chemical reactions such as sodium, neon, and boron. Elements are the basic chemical compositions that make up organisms and connect

between Mars and Jupiter. Meteor showers occur when asteroid particles enter the earth's atmosphere at very high speeds. When they strike the atmosphere, the meteors rub against the air particles and create frictions. When the heat vaporizes from the meteor, it creates what we call a "shooting star". The meteorites resemble a black crust in the form of ash on their surface. When a meteorite falls through the atmosphere of the Earth, a thin layer on the outer surface. Metals are made of three minerals:

northern lights, or better known as the dancing lights. Aurora Borealis is one of the most exotic and difficult concepts in astronomy. The colours of aurora borealis are fomed by the collision of gas particles in the Earth’s atmosphere with charged electrons from the sun’s atmosphere. So, today I will inform you about the different types of gas particles that are involved in the production of the colours of aurora borealis. I obtained the all the information about Aurora Borealis from the book entitled

definition is the increase in the earth's ocean and near surface temperatures. In the last several decades, there have been numerous debates regarding global warming. The vast majority of the scientific community now agrees that global warming is caused by the increase in greenhouse gasses in the atmosphere. What is more important, cheap energy or sustaining human life for the next 100+ years? Global warming is no longer fiction; scientific studies have proved that the earth's climate is under going a period

NATURAL OR MAN-MADE There is no question that there is an increase in Earth’s temperature and we are experiencing what is referred to as global warming. The Earth has experienced this many times in history on a much larger scale, but, humans did not exist (and would not have been able to exist) at the time. The questions now are whether human actions are accelerating the process of global warming and possibly decreasing Earth’s future sustainability; and, if so, what, if anything, can we do to ensure

the earth’s atmosphere, fisheries, grasslands, water, forests, roads and even population growth. However, in this essay, I am going to analyze this tragedy by examining the “common-ness” of the Earth’s atmosphere and the apparent difficulty of having a universally recognized regulatory institution. This is precisely because of the absence of a “world government” and the state of chaotic anarchy among nation-states in the international community. The degradation of the Earth’s atmosphere is a
