This technique, known as Supersonic Retropropulsion, works similarly to how a rocket launches. After delivering its package to Low Earth Orbit, the rocket will turn around and propel itself towards Earth. Once it enters the atmosphere, the

human activities contribution to79% of Canada’s total emission. CO2 is released into the atmosphere by means of burning fossil fuels, coal, and land clearance. As the concentration of CO2 accumulates into the atmosphere, climate change and global warming becomes worse. Canada is the leading country in piloting the carbon dioxide capture and storage (CCS) technology to reduce the emitted CO2 into the atmosphere by storing the captured CO2 underground, it could reduce GHG by 14-19% before 2050.

(American Geophysical Union, 2014). The Earth's surface temperature has to be just right for humans, not too cold and not too hot. Thanks to the natural greenhouse effect, which has kept the Earth warm. It’s a phenomenon where the earth's atmosphere traps solar radiation, caused by the presence in the atmosphere of gases such as carbon dioxide, water vapor, and methane that allow incoming sunlight to pass through but absorb heat radiated back from the earth's surface. As there are naturally occurring

* What is Earth and Space science? * The study of the universe and its functions. * Types of Earth and Space sciences * Geology - The study of how the Earth’s materials, structures, processes, and organisms have changed over time. Geologists try to understand the history of our planet, by reading the physical structures and processes. Geologists study various forms of Earth formations such as: marine, sedimentology (rocks), pedology (soil), structural, and geomorphology (landforms)

life. We humans are constantly learning more and more about this planet. Earth has been humanity’s mysterious home since the origin of our species, but in the last century or so there has been an alarming trend taking place. We have experienced the Earth’s temperature rising. Global warming is the name of the phenomenon that has taken place over approximately the past 133 years, and according to NASA, it is an un-debated fact that the average temperature on Earth has increased one and a half degrees

identified as significant causes of recent climate change, often referred to as "global warming". Scientists actively work to understand past and future climate by using observations and theoretical models. A climate record — extending deep into the Earth's past — has been assembled, and continues to be built up, based on geological evidence from borehole temperature profiles, cores removed from deep accumulations of ice, floral and faunal records, glacial and periglacial processes, stable-isotope and

Research Paper EN 102 Climate Change – Global Warming Climate change has become really important for the whole world due to its drastic change, because of the release of carbon dioxide and other gases in the Earth’s atmosphere. The climate on Earth has always been a subject of change. From history we know that there was an ice age on the planet Earth that ended about 10,000 years ago. The time has passed; “people have developed advanced industry, and technology, discovered fossil fuels and

1. Define biosphere. Describe the part of the biosphere where humans can survive. Biosphere is defined as the parts of the land, sea, and atmosphere in which organisms are able to live. The biosphere is an irregularly shaped, relatively thin zone in which life is concentrated on or near the Earth's surface and throughout its waters; and all the Earth's ecosystems considered as a single, self-sustaining unit ("Biosphere - Definition of Biosphere by the Free Dictionary", 2014).

the core. The Earth’s lithosphere consists if crust and the upper mantle. THE STRUCTURE Earth has a diameter of about 12,756 km (7,972 mi). The Earth's interior consists of rock and metal. It is made up of four main layers: 1) the inner core: a solid metal core made up of nickel and iron (2440 km diameter) 2) the outer core: a liquid molten core of nickel and iron 3) the mantle: dense and mostly solid silicate rock 4) the crust: thin silicate rock material Earth's Crust: There
