Why is our planet the only planet to have life?
Our planet is the perfect distance from our sun to receive enough light to keep water in a liquid form, our atmosphere has a well balanced amount of Nitrogen, Oxygen, Carbon Dioxide and other gases to support life and trap heat within the planet. Our planet also has water, a very important 'ingredient' for life. It is also a 'rock' planet not a gas planet and has a strong enough gravitation pull to hold on to our atmosphere, without this gravity the gases in our atmosphere would drift into space. Which is why Mars's atmosphere contains a very little amount of Oxygen, it when into space over millions of years. All other planets we have seen in our galaxy do not have the requirements for life, they are either too hot, too cold, too toxic, etc. And the odds of a planet meeting these requirements are astronomical.
How is air pulled towards earth?
During the formation of the Earth, various gases were released from the surface, including carbon dioxide, nitrogen, and water vapor. Once the Earth reached a large enough mass, it had enough gravity that these gases didn't drift off into space; they were held to the surface by gravity. Earth's magnetic field also helps to keep the atmosphere on Earth, by shielding it from solar winds that would otherwise bombard the atmosphere and send its gases into space. The Moon has no atmosphere because its mass is too low, and thus it doesn't have enough gravity to hold onto an atmosphere. In addition, it has no significant magnetic field. Mars may have once had a much denser atmosphere, but it lost its magnetic field billions of years ago, and solar winds eroded the atmosphere until it became very thin, like it is today.
Could the moon have an artificial atmosphere?
No, the moon could no keep an atmosphere if one were created.
What is the benefit of the atmosphere trapping energy from the sun?
The benefit of the atmosphere trapping energy from the sun is to keep Earth warm.
What is earth like?
The atmosphere is composed of air. You and I are both surrounded by it, and we would die very quickly from lack of oxygen (among other problems) if we weren't. That being the case, you can observe what the atmosphere is like quite easily. You're in it.
Animals help keep the gases in the atmosphere in balance by?
Plants and animals help to maintain a balance of carbon dioxide in the atmosphere by cellular respiration and photosynthesis. Photosynthesis releases oxygen and cellular respiration releases carbon dioxide.
Which two processes keep the concentration of CO2 in the atmosphere stable?
Respiration and photosynthesis
Having more greenhouse gases in the atmosphere will do to the average temperatures in the atmosphere and why?
Green house gases will keep more of the heat that enters the earth. It will raise the temperature
Respiration and photosynthesis keep the levels of carbon dioxide and oxygen in the atmosphere?
fairly constant
What greenhouse gases do in the atmosphere?
Greenhouse gases keep the earth warm.Too much greenhouse gas is causing global warming.
Which atmospheric gases do photosynthesis and cellular respiration help keep constant?
explain how photosynthesis maintain the composition of air?
How can the greenhouse effect and greenhouse gases cause problems with earths energy budget?
Earth's energy budget has been balanced for thousands of years. The natural greenhouse effect allows enough heat in and out of the atmosphere to keep it warm enough for life. Additional greenhouse gases, which we are now adding to the atmosphere and causing problems with the budget and the earth is warming up. This warming is causing climate change.

Why do gases surround the Earth?
Gravity is able to keep the heavier gases close to the Earth's surface, but light gases such as helium rise in the atmosphere and are swept away by the Solar Wind.
What atmosphere gas helps to keep earth warm?
Carbon dioxide is one of the greenhouse gases that helps to keep earth warm.
Which is one way trees help keep some of the gases in the air balanced?
It releases carbon dioxide and takes in oxygen
What two things keep your atmosphere warm?
The natural greenhouse effect, helped by greenhouse gases and the carbon and water cycles of the earth keep the atmosphere warm. Greenhouse gases keep back some of the sun's heat so it doesn't radiate back out to space. This has kept the earth warm for millions of years.
