What layer of the atmosphere is the nearest to earth?
layer close to the surface is the top part of the mantle
How does water stays on Earth's surface?
Gravity keeps water on Earth. Note that if you consider water is just the liquid substance, this seems obvious, but if you consider it is also a gas (water vapour), which can move away from the surface of the Earth with the air , then it isn't so obvious. Nonetheless, water vapour, the molecule H2O, is still too heavy to escape the Earth's gravitational pull. As a contrast, consider Mars or the Moon, where water will not stay on the surface, and escapes into space, such that there is none left on those bodies. Other gases do escape, such as hydrogren or helium.
The Earth's atmosphere extends about how many miles above the earth's surface?
It extends about 75 miles. Earth's Atmosphere The Earth is surrounded by a blanket of air, which we call the atmosphere. It reaches over 560 kilometers (348 miles) from the surface of the Earth, so we are only able to see what occurs fairly close to the ground. Early attempts at studying the nature of the atmosphere used clues from the weather, the beautiful multi-colored sunsets and sunrises, and the twinkling of stars. With the use of sensitive instruments from space, we are able to get a better view of the functioning of our atmosphere.
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.
Why is air pressure greatest at the Earth's surface?
Because as you get closer to the surface of the earth, the more air that is on top of you. At the top of the atmosphere, there is no air, and everything is a vacuum, where you have no weight. When you get close to the earth, the weight of the air builds until it when you're at the very lowest point of the earths surface, all the air in the atmosphere above you is pressing down.
What keeps Earth's atmosphere close to the surface?
The gravitational pull keeps the Earth's atmosphere close to the surface...
What keeps the atmosphere near the surface of the earth?
The gravitational force between the Earth and the atmosphere holds the atmosphere close, just like it holds you close to the Earth. (ground)

Why do the gases in the earth atmosphere stay close to the surface of the planet?
Mostly for the same reason you stay close to the surface of the planet - gravity!

The layer of gas closest to earth?
the lowest layer of the atmosphere is the trosospere
Why is it important that a satellite be above Earths atmosphere?
Please remember that close to Earth's surface, a satellite must move at a speed of about 7900 meters/second. If it is inside the Earth's atmosphere, the force of friction will make the satellite lose energy. As a result, it will soon crash to the Earth's surface.
Can the earth have less gravity and still have a air?
Yes. Both Mars and Venus have weaker gravity than Earth does, but still have atmospheres. Mars has a very thin atmosphere which may have been close to the density of Earth's atmosphere in the distant past, despite having less than half the surface gravity. Venus has about 90% the surface gravity that Earth does, but has an atmosphere many times denser than Earth does.
