Antarctic ice is formed very slowly when ice crystals -- the only forms of precipitation over 99.9% of the continent -- stick to existing ice and are covered with other ice crystals. Over millenia, the ice becomes so heavy that it presses out all minerals other than oxygen and hydrogen, and becomes clear.

Does the moon have ice caps?

Yes, the moon has ice caps at its poles. These ice caps are composed mostly of water ice, and they have been confirmed by various spacecraft missions. The ice might have come from comets or possibly accumulated from water molecules present on the moon's surface.


Why can't you get water from ice caps?

Ice caps are made of solid ice, and not liquid water, so you can't directly get water from them. To obtain water from ice caps, the ice must first be melted to convert it into liquid form. This requires energy input to raise the temperature of the ice, which can be a challenging and resource-intensive process.


Why does the melting of ice caps lower the concentration of salt in the ocean?

Melting ice caps release freshwater into the ocean, which dilutes the saltwater and lowers its overall salinity. This influx of freshwater can disrupt ocean currents and impact marine ecosystems that rely on specific salinity levels for survival.


What planet has polar ice caps 100 percent water ice?

Of what are Mars' ice caps made?

Mars' ice caps are predominantly made up of water ice, with some layers also containing a mix of frozen carbon dioxide, also known as dry ice. The white polar caps are primarily composed of water ice, while the seasonal polar caps are a combination of water ice and frozen carbon dioxide.


Is an ice caps water fresh water or salt water?

Ice caps are made of fresh water. When this ice melts into the ocean, it contributes to the salinity of the water in that area.


Was there water flowing on Mars?

No, but there is ice in the caps.


Which three planets have polar ice caps?

Mars, Earth, and Pluto have polar ice caps. Mars' polar ice caps are primarily made of water and carbon dioxide ice, Earth's polar ice caps are primarily made of frozen water, and Pluto's polar ice caps are a mixture of methane and nitrogen ice.


What planet has polar ice caps?

Mars has polar ice caps at its north and south poles. These ice caps are primarily composed of water ice and carbon dioxide ice. The polar ice caps on Mars play a significant role in the planet's climate and atmospheric composition.


How much fresh water is stored in ice caps?

It is estimated that ice caps and glaciers contain about 68.7% of the world's fresh water supply. This frozen water is stored primarily in Greenland and Antarctica, with smaller amounts in other glaciers around the world. Melting of these ice caps contributes to global sea level rise.


Does the Mars have water?

Mars does have water, it is just frozen in its ice caps.


Does Mars or its moons have water?
