1. 10.1 Distribution of Water
Water exists everywhere on Earth, and covers 70% of its surface. 97% of this water is found in the oceans.
Another 2% is ice and snow, leaving only 1% as fresh water found in the ground, rivers, lakes and streams.
Finding fresh water to drink is a challenge in many places, as most fresh water is under the ground.

2. The Water Cycle Earth is the only planet with water in all 3 states
Water is continually cycling through the water cycle
Heat energy from the Sun causes these changes to drive the water cycle.
Solid  Liquid = Melting
Liquid  Gas = Evaporation
Gas  Liquid = Condensation
Liquid  Solid = Solidify/Freeze
Solid  Gas = Sublimation
Gas  Solid = Deposition

4. The Water Cycle (continued)
The water cycle occurs everywhere, not just oceans
Water evaporates when it is warmed, and then condenses in the atmosphere as clouds when it cools and falls as
precipitation. The water then runs-off back to storage basins, or soaks
into the ground.
A hydrologist is a scientist who studies water systems
An oceanographer studies oceans specifically
