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.
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.
Does the moon have atmosphere?
the moon does not have liquid
What is it called when liquid water falls from the atmosphere?
Rain? precipitation
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.
What cause liquid water to evaporate?
The continuous movement of water molecules can lead some molecules at the surface to escape in the atmosphere as a gas.
What are the causes of evaporation?
Some molecules from the surface of the liquid gain more energy and are able to escape in the atmosphere.
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.
What best explains what happens when liquid water evaporates to form water vapor?
When water molecules at the surface gain sufficient energy they can escape in the atmosphere.The energy of water molecules increase by a temperature increase and some molecules at the surface can escape in the atmosphere.
How Do Liquid Water Molecules Escape Into Gas State?
Evaporation is the process of water molecules in liquid water escape into the air as water vapor.
What happens to water molecules as water evaporates?
The hydrogen bonds between the water molecules in the liquid are broken.
Why can liquid boil at low pressure?
it becomes easier for the molecules to escape

What causes evaporation of water?
When water molecules at the liquid surface gain sufficient energy they can escape in the atmosphere. Evaporation (not vaporization) occur at any temperature; a higher temperature increase the rate of evaporation.
Why does warm water evaporate faster then cold water?
At higher temperatures waer molecules at the surface of the liquid have more energy and is more simple to escape into atmosphere.
Why can liquid boil at a low pressure?
Reducing the air pressure allows the molecules to escape
What happens when liquid water molecules escape from the surface enter into what?
evaporation
