of the Hydrologic Cycle:
of Hydrologic Cycle
- is water evaporating from the ground and transpiration by plants. evapotranspiration
is also the way that water vapor re-enters the atmosphere.
- is the process of water changing
from a vapor to a liquid. Water vapor in the air rises mostly by convection.
This means that warm, humid air will rise, while cooler air will flow downward.
As the warmer air rises, the water vapor will lose energy, causing its
temperature to drop. The water vapor then has a change of state into liquid
- is water being released from clouds as rain, sleet, snow or hail. Precipitation
begins after water vapor, which has condensed in the atmosphere, becomes
too heavy to remain in atmospheric air currents and falls.
of the precipitation that reaches the Earth's surface seeps into the ground.
- is the downward movement of water through soil and rock. Percolation
occurs beneath the root zone.
- is precipitation that reaches the surface of the
Earth but does not infiltrate the soil. Runoff can also come from melted
snow and ice.
