What else can I help you with?
When earths early atmosphere formed which gases where lost because earths gravity was too weak?
Hydrogen and helium
What occurs when a high level of charged particles outside the earths atmosphere manages to penetrate the atmosphere?
auroras
When occurs when a high level of charged particles outside the earths atmosphere manages to penetrate the atmosphere?
auroras
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.
Can you escape gravity by going above the earths atmosphere?
No. To even reduce it by 75% you must travel out to 4000 miles.
What two things does momentum count on to keep in act?
Outside earths atmosphere its Gravity, and on Earth its Mass and Velocity.
Why spacecraft get hot while enter into the earths atmosphere?
A spacecraft has to work against the air friction when it enters our atmosphere. Thus it gets heated a
The earths atmosphere came from where?
Gravity pulled it in.
What is the the earths moons atmosphere?
There is no atmosphere on the moon. There is insufficient gravity to keep an atmosphere there.
What is the difference between the earths atmosphere and the earths gravity?
The two are completely unrelated.
What is the action of the spacecraft leaving the earth called?
escape velocity if its leaving earths gravity
What is the difference between a plane and spacecraft?
An aircraft flies in the Earths atmosphere, whereas a spaceship flies above the atmosphere.
Why is hubble located on the outside of earths atmosphere?
because it has to be
What force holds the particles of air in earths atmosphere?
The Earth's gravity.
When earths early atmosphere formed which gases where lost because earths gravity was too weak?
Hydrogen and helium
What force holds the atmosphere to earths surface as it travels through space?
Gravity.
How would the gravity of mars affect the landing of a spacecraft?
Does mars' gravity affect other objects. yes it does but the gravity is 38% of the earths gravity and if doesn't affect objects then it will have no moon.
