When the earth cooled down how did it affect the composition of the atmosphere?
As the Earth cooled down, gases such as carbon dioxide and water vapor in the atmosphere started to condense and form oceans. This led to a reduction in the amount of these greenhouse gases in the atmosphere, resulting in a shift towards the composition seen today with nitrogen dominating the atmosphere.
About how many years ago do scientists suggest that earth cooled enough for water vapor to condense?
THEY THINK about 3.9 billion years ago (: 4.4 billion years ago(:
What keeps the oxygen inside earth?
Gravity is what keeps oxygen (and other gases) from escaping Earth's atmosphere. The gravitational force of Earth is strong enough to hold on to gases in its atmosphere, including oxygen. This allows for the maintenance of a stable and breathable atmosphere on the planet.
If an object that enters the Earth atmosphere does not completely disintegrate its remains can impact the Earth?
When an object enters the Earth's atmosphere and does not completely disintegrate, any remaining fragments can impact the Earth's surface. Depending on the size and speed of the object, these impacts can cause damage ranging from small craters to significant destruction if the object is large enough. This is why monitoring and tracking near-Earth objects is important to assess potential risks.
What holds the earth atmosphere?
Gravity hold the atmosphere to the Earth. But other factors do cause earth to loose some atmosphere to space continuously.
What holds the atmosphere to the earth?
The earths gravity. The more mass a body has, the more gravity, The Earth has enough mass to hold an atmosphere. The Moon, on the other hand, is not massive enough, and so does not have a high enough gravity, which prevents it from holding an atmosphere.
Which could cause a satellite to descend low enough that it burns up in earth's atmosphere?
air resistance
Which could cause satellite to descend low enough that it burns up in Earth's atmosphere?
jkkkkkkkk
What could cause a satellite to descend low enough that it burns up in earth's atmosphere?
Friction.The Earth's atmosphere never really ends, it just gets thinner and thinner until it seamlessly merges into the solar atmosphere. Satellites in low Earth orbit experience enough drag that they can slow down, which results in them dropping nearer to Earth, where they experience even more drag.
What occur in the nonliving part of the water cycle?
water vapor in the atmosphere condense and falls to earth surface as rain or snow
How does the Greenhouse effect cause a change in the earth axis tilt angle?
It doesn't! The greenhouse effect keeps the earth warm enough for life by keeping warm gases in the atmosphere. It has no effect on the tilt of the earth.
Why does the earth have a atmophere?
Mainly because Earth has a large enough mass, and therefore a large enough gravity, to keep an atmosphere.

Why can elements produced in the sun but not in the earth atmosphere?
The earth's atmosphere is not hot enough for thermonuclear fusion to take place.
What is the cause of tremendous heat on Venus?
Venus has a very strong greenhouse effect. A greenhouse effect is when the gases in the atmosphere trap more of the Sun's heat. A lot of carbon dioxide, a very dense atmosphere, and a thick blanket of clouds help trap the sun's heat. The transfer of heat by atmospheric currents means both the night and day sides are almost the same temperature. Venus is like this because it is closer to the Sun than Earth so it is naturally hotter. On Earth, it is cool enough for water to condense and form oceans, where carbon dioxide can be absorbed. On Venus, water cannot condense in order to absorb the carbon dioxide so all of it stays in the atmosphere. The temperature is about 460 °C.

What must occur before precipitation can fall to earth's surface?
Before precipitation can fall to Earth's surface, water vapor in the atmosphere must condense and form clouds. Once the clouds reach a point where they can no longer hold the condensed water, precipitation such as rain, snow, sleet, or hail will fall to the surface.
