ERT-1.G—Explain the steps and reservoir interactions in the hydrologic cycle

Explain the steps and reservoir interactions in the hydrologic cycle.

• The hydrologic cycle, which is powered by the sun, is the movement of water in its various solid, liquid, and gaseous phases between sources and sinks.
• The oceans are the primary reservoir of water at the Earth’s surface, with ice caps and groundwater acting as much smaller reservoirs.
• Enduring understanding ERT-1: Ecosystems are the result of biotic and abiotic interactions.
