What is the cryosphere?

The cryosphere is the part of the earth that is frozen. The word "Cryos" from cryosphere comes from the greek "krios" which means "cold" and "sphere", well that´s just another way to describe the Earth. So you can think about it as a "cold sphere".

The cryosphere also includes ice on top of rivers and lakes, snow, the ice caps and any other thing that is part of the earth and is frozen for at least some part of the year.

Having explained that, we can easily conclude that wind and plants aren´t part of the cryosphere. But what about rivers? If they were completely frozen for some part of the year, then they would be considered part of the cryosphere.

the answer is mosques. they are an important part of islamic culture.
