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 else can I help you with?
What is it called when liquid water falls from the atmosphere?
When liquid water falls from the atmosphere, it is called rain.
What is the answer of after the blank of liquid water on earths surface water vapor rises into the atmosphere?
The answer to the blank in the phrase "liquid water on Earth's surface _____ water vapor rises into the atmosphere" is "evaporates." When liquid water evaporates, it transforms into water vapor, which then rises into the atmosphere. This process is a key component of the water cycle, contributing to weather patterns and climate regulation.
What is the process of liquid water changing into the water vapor and entering the atmosphere called?
evaporation
The movement of water into the atmosphere as it changes from a liquid to a gas is called?
Evaporation.
What planet has water and an atmosphere?
Earth is the only planet in our solar system known to have liquid water on its surface and a dense atmosphere suitable for supporting life as we know it. Other planets like Mars might have some water ice at the poles, and Venus has a thick atmosphere but no liquid water on its surface.
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?

Does the moon have an atmosphere or running water?
The moon has no atmosphere or liquid water.
What is it called when liquid water falls from the atmosphere?
When liquid water falls from the atmosphere, it is called rain.
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
What is an example of a solid a liquid and a gas 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.
Is water the most abundant liquid in earth's atmosphere?
No, water vapor is the most abundant gas in the Earth's atmosphere, not liquid water. Water vapor makes up around 1% of the atmosphere.
How does liquid water return to the atmosphere?
Evaporation
What is the only substance thatexest as a solid liquid and gasses in the earths atmosphere?
Water is the only substance that commonly exists as a solid, liquid, and gas in Earth's atmosphere. Solid water is ice, liquid water is water, and gaseous water is water vapor.
What is the only substance that exists as a solid liquid and gas in the Earth's atmosphere?
water
Could water exist as a liquid on Earth if it did not have an atmosphere?
Water could exist as a liquid on Earth without an atmosphere in specific conditions where the temperature and pressure allow for liquid water to form. However, without an atmosphere, these conditions would be less stable and water would be more likely to evaporate or freeze quickly due to the lack of atmospheric pressure and insulation.
