Hubble has viewed many stars dying and being born, and has also seen distant planets and galaxies. Earth’s atmosphere blocks out certain types of light from space thus effecting how much of space can be viewed from a telescope on Earth, Hubble is outside of Earth’s atmosphere and is orbiting around the

inhaling dangerous chemicals that have found their way into the air. We as humans depend on the air around us to live, without it we would die. We rely on this as an essential source for living. Air pollution includes all contaminants found in the atmosphere. It is another major problem that is yet to be solved. These dangerous substances can be either in the form of gases or particles. The air is 99.9% nitrogen, oxygen, water vapor, and inert gases. Air pollution is a common term meaning the dirtying

warming is the gradual increase of the temperature of earth's atmosphere and oceans. Over the past century the average temperatures have gone up by just over one degree. This may not seem like much, but many scientists agree that the earth's temperatures are starting to increase at a faster rate. What Causes It? Global warming occurs when greenhouse gases, such as carbon dioxide, nitrous oxide, and methane trap heat inside the earth's atmosphere. Think about what happens when you open your car

Tropical Rainforest Megan L. Cleveland SCI/256 JUNE 14, 2015 Mr. Davis Tropical Rainforest An ecosystem is a unique environment where every living thing is interdependent, and one of the most complex yet most interesting ecosystems in the world will be found in the rainforest. The dark and recessed thick plant growth make it one of the most moist places on Earth. If a person studies the plants and animals that compromise the rainforest ecosystem; a person can gain a basic understanding

CONCLUSION 27 Bibliography 28 Abstract: Throughout its long history, earth has warmed and cooled time, and again. Climate has changed when the plant received more or less sunlight due to stubble shifts in its orbit, as the atmosphere or surface changed or when the sun energy varied. However, in the past century, another force started to influence earth climate: humanity. How can we be certain that human released greenhouse gases are causing the warming? How much will

find out how much carbon dioxide was in the atmosphere and made connections between changes in the atmosphere. Naturally the amounts of carbon dioxide in the atmosphere change depending on the time of year. Carbon dioxide goes up in the fall and winter months and down in the summer and spring months. Now due to pollution the amounts of carbon dioxide in the atmosphere are unstable. Global warming is cause by carbon dioxide being trap in the atmosphere by green house gases which in turn increases

and outgoing radiation from Earth. Due to absorption, reflection and scattering throughout the atmosphere, the Earth’s surface only receives 24% of the incoming insolation. Whilst the atmosphere has a net deficit of energy, the surface has a net gain, except for the polar regions. This difference therefore results in movement of energy from the surface to the atmosphere. Several factors affect the amount of insolation and thus the heating of the atmosphere, including latitude, seasons, diurnal range, altitude, ocean currents

surface and atmosphere, making life possible. As Earth warmed up, this solar energy is radiated by thermal radiation or infrared heat, traveling directly out to space, thus cooling the Earth. However, some of the outgoing radiation is re-absorbed by carbon dioxide, water vapor and other gases in the atmosphere and is radiated back to Earth’s surface; these gases are known as greenhouse gases due to their heat-trapping capacity. This re-absorption process is naturally good; the Earth’s average surface

Global Warming: Fact or Fiction Global Warming: Fact or Fiction American Intercontinental University Clarice E. King Abstract Global warming is the rise in average temperature within the Earth’s oceans and atmosphere. Some believe that it’s not a real development at all and may be a hoax by some scientist to gain government funding. The average temperatures around the world have risen 1.4 degrees Fahrenheit (0.8 degrees Celsius) since 1880. The last two decades have been the hottest
