Which planet roughly the same size of earth has its own atmosphere?
Venus is roughly the same size as Earth and has its own thick atmosphere composed mainly of carbon dioxide. This atmosphere creates a strong greenhouse effect, leading to extremely high surface temperatures on Venus.
How does the earth hold its Atmosphere?
Earth holds its atmosphere due to the force of gravity. Gravity pulls the gases of the atmosphere towards the surface of the Earth, preventing them from escaping into space. The Earth's gravity is strong enough to hold gases like nitrogen, oxygen, carbon dioxide, and others close to its surface.
What planet is Its atmosphere is mostly nitrogen?
Planet Earth - about 80%.
If there is no atmosphere on Mars how can there be winds?
Although Mars has a thin atmosphere compared to Earth, it is still capable of generating winds. The winds on Mars are created by differences in temperature and pressure, which drive atmospheric circulation patterns that cause wind movement across the planet's surface. The lack of atmosphere means the winds on Mars are not as strong as those on Earth.
How thick is the martian atmosphere?
Much thicker, almost certainly at least as thick as the diameter of the earth. Its pressure is much higher as well due to the high mass of the planet and its atmosphere and the strong gravity.
Is earth strong or weak?
Is earths atmosphere string or weak
Why is moon not as warm as the earth?
Because the Moon does not have an as strong atmosphere as the Earth does, so the heat cannot be contained.
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.
What is the Mercurys atmosphere compared to earth?
Mercury's atmosphere is extremely thin compared to Earth's. It is composed mostly of oxygen, sodium, hydrogen, helium, and potassium, but its overall density is about 100 trillion times less than Earth's atmosphere. Mercury's weak gravity isn't strong enough to retain a thick atmosphere like Earth's.
What 2 chemicals was the Earth's first atmosphere composed of?
The Earth's first atmosphere was composed mainly of hydrogen and helium. These gases were eventually lost to space due to the Earth's gravity not being strong enough to hold on to them.
How planet earth was able to maintain a very comprehensive atmosphere?
Because it has sufficient gravity and a strong magnetosphere.
Why was earth able to hang on its atmosphere?
Earth is able to retain its atmosphere due to its gravity. The gravitational force of Earth is strong enough to hold on to the gases of the atmosphere, preventing them from escaping into space. This creates a stable environment that allows for life to exist on the planet.
Which planet roughly the same size of earth has its own atmosphere?
Venus is roughly the same size as Earth and has its own thick atmosphere composed mainly of carbon dioxide. This atmosphere creates a strong greenhouse effect, leading to extremely high surface temperatures on Venus.
Does the atmosphere rotate with the Earth?
No, the atmosphere does not rotate with the Earth. The Earth's rotation causes the atmosphere to move with it, but the atmosphere itself does not rotate independently.
Why do you have most of atmosphere near the surface of the earth?
Near surface gravity is more strong which hold atmospher strongly then high
What is the atmosphere of the earth like?
There is not much atmosphere on earth
Our atmosphere is attracted by earth's what?
our atmosphere is attacted by earth
