The Moon does not have enough gravity to form a thick atmosphere. Intense sunlight reaches and heats the surface. Liquid water would be ionized and escape back into space as hydrogen and oxygen ions.
The water on the Moon is in the form of ice in deep crater shadows. Sunlight cannot reach this ice to melt and vaporize it.

Why does earth have a liquid water supply and the moon?
Earth has a liquid water supply due to its distance from the sun, its atmosphere, and its geologic activity which helps maintain temperatures suitable for liquid water. The moon lacks these factors, leading to its lack of liquid water supply.
Why does earth have a liquid supply of water and the moon does not?
Earth has a liquid supply of water due to its atmosphere, gravity, and positioning in the habitable zone around the sun. The moon lacks these factors, leading to the absence of a liquid water supply on its surface.
The only planet with a bountiful supply of water?
Earth is the only planet with a bountiful supply of water.
Why does earth have a liquid water supply?
Water itself is one of the most abundant compounds in the universe. Earth is at the right distance from the sun, the right amount of greenhouse effect, and the right amount of pressure for water to be liquid on most parts of its surface.
Why does earth have q liquid water supply and the moon does not?
Earth's liquid water supply is due to its unique position in the habitable zone of the Sun, where temperatures allow for water to exist in its liquid state. The moon lacks significant quantities of liquid water due to its smaller size, weaker gravity, and lack of a substantial atmosphere to retain water molecules.
Why does earth have a liquid water supply and the the moon does not?
Earth has a liquid water supply due to its thicker atmosphere and sufficient gravitational pull to retain water in liquid form. The moon, on the other hand, lacks a significant atmosphere and has lower gravity, causing any water there to either freeze or evaporate into space.
What percent of total water on the planet is fresh liquid water?
Approximately 0.3% of the Earth's total water supply is fresh liquid water available for human consumption and use. This freshwater is found in rivers, lakes, and groundwater sources. The majority of Earth's water is saline and found in oceans and seas.
Why does earth a liquid water supply an Venus does not?
Venus is closer to the sun, so it's hotter there. Water needs to stay below 100 deg C to remain a liquid, and Venus is hotter than that.
Is water the lightest liquid on earth?
No, water is not the lightest liquid on Earth. Liquid hydrogen and liquid helium are lighter than water because they have lower densities.
Why does earth have a liquid water supply but mars does not?
Earth has a stable liquid water supply primarily due to its optimal distance from the Sun, which allows for a suitable temperature range, along with a thick atmosphere that creates pressure to keep water in liquid form. In contrast, Mars is farther from the Sun, leading to colder temperatures, and its thin atmosphere lacks the necessary pressure to support liquid water, causing any surface water to freeze or evaporate. Additionally, Mars has lower gravity, which contributes to its inability to retain a substantial atmosphere over geological time, further limiting the presence of liquid water.
What does the earth's hydrosphere do?
it is earth's water supply
Why does earth have liquid water supply in mars does not?
Earth has a stable supply of liquid water due to its optimal distance from the Sun, a suitable atmosphere that maintains pressure, and a magnetic field that protects against solar radiation. In contrast, Mars lacks a thick atmosphere, leading to low pressure that causes water to freeze or evaporate quickly. Additionally, Mars' surface temperatures are generally too cold for liquid water to exist without being under pressure, and it has lost much of its water over time due to atmospheric escape. These factors contribute to Earth's abundant liquid water, while Mars remains arid.
