|
List 3 types of water movement and describe
|
1) Surface-to-Air: moisture enters the atmosphere by evaporation and transpiration
2) Air-to-surface: moisture returns to Earth by condensation and precipitation 3) Movement on and beneath Earth's Surface: process of "run-off" returns from the land to the sea |
