Answer 1

Seawater can evaporate and then condense to form clouds.

Water stored as a gas in a cloud can condense and then freeze to form a glacier.

Most of the water on Earth is in the oceans. In fact, according to the U.S. Geological Survey, only about 2.5% of all the water on the planet is freshwater. Moreover, that water is not uniformly distributed or consistently easy to access. Only about 0.3% of the freshwater on Earth is stored in streams, rivers, lakes, and wetlands.
