What can you tell me about the cryosphere and the hydrosphere?

Question

No wikipedia entries please.

Answer 1

The cryosphere  gives scientists valuable insights into how and why the earth’s climate has changed in the past, how it is currently changing, and what may lie ahead. Ice at the poles and in glaciers contains detailed records of past climate, including bubbles that capture samples of the earth’s ancient atmosphere. By examining ice cores—cylinders of ice taken from deep below the surface—scientists gather data dating back hundreds of thousands of years

Anything that scientists describe, when it comes to water, is a part of the hydrosphere. That water may be at the bottom of the ocean or in the top layers of the atmosphere; it is all a part of the hydrosphere.
