Module 2: Water, water almost everywhere

The presence of water in solid, liquid, and gaseous forms is one of the primary factors that distinguishes Earth from its neighbors in the solar system.

In this module, students compare the amount of land and water on Earth; consider craters as evidence of a lack of water on other planets; define and locate water bodies found on Earth; and identify changes that occur in these water bodies.
