What caused Mars' atmosphere to decinagrate and lose all its liquid water?

As Mars has cooled, its core has solidified and its geodynamo stopped. The loss of Mars' magnetic field allowed more solar energy to reach the surface. That solar radiation heat dissipated the surface water and atmosphere.
Also, because Mars' gravitational field is not as strong as earth's, it was much easier for atoms and molecules at the top of the atmosphere to escape to space. Over millions of years this process led to the loss of most of Mars' atmosphere.

What is it called when liquid water falls from the atmosphere?
Rain? precipitation
What is the process of liquid water changing into the water vapor and entering the atmosphere called?
evaporation
Can water exist on a planet with no atmosphere?
Atmospheric pressure is an important factor in keeping liquid water on the surface of a planet. With no atmosphere, liquid water would quickly escape into space. It would depend on various factors such as the temperature and escape velocity of the planet of course. Scientists think liquid water existed on Mars in the past when the atmosphere was a lot denser. Water does exist on the surface Mars, but only as ice.
If Mars did have liquid water at one time what happened to it and why?
One popular theory is that when mars lost its atmosphere, the liquid water evaporated into space.
How do the hydrosphere and atmosphere compare?
The hydrosphere is the body of liquid water on the earth, and the atmosphere is the body of gas around the earth.
There is a great deal of erosion on the moon caused by wind and water?
No, the moon does not have an atmosphere; no atmosphere ---- no wind and no liquid water.
What is the movement of water into the atmosphere as it changes from a liquid to a gas is called .?
The movement is caused by evaporation from the Sun and wind, and is part of the water cycle.
Could water exist as a liquid on earth if did not have an atmosphere?
could water exist as a liquid if we don't have a atmosphere
Could water exist as a liquid on Earth if it did not have an atmosphere?
could water exist as a liquid if we don't have a atmosphere
Does the moon have an atmosphere or running water?
The moon has no atmosphere or liquid water.
What is an example of a solid a liquid and a gas in the atmosphere?
Gas in atmosphere: argon Liquid in atmosphere: water (as rain) Solid in atmosphere: dust
What is a example of a solid a liquid and gas in the atmosphere?
Gas in atmosphere: argon Liquid in atmosphere: water (as rain) Solid in atmosphere: dust
Why does water change from a liquid to a gas in evaporation?
Evaporation is caused by the continuous Brownian movement of water molecules; several molecules gain sufficient energy to escape in the atmosphere.
How does liquid water return to the atmosphere?
Evaporation
Why is water droplet a liquid?
because water in the atmosphere is in a form of vapor
Is there liquid water on the asteroid belt?
No. None of the asteroids have atmosphere, and liquid water cannot exist in the vacuum of space.
What is the most abundant liquid in the earths atmosphere?
In some conditions this is liquid water. Generally water exist as a gas.
