hydrosphere Flashcards
Evaporation
The transfer of water from the sea to the air as water vapour.
Condensation
Water vapour (gas) changes back into water (liquid). it forms small droplets which are visible as clouds.
Precipitation
Water falls to earth as either liquid (rain) or in a frozen state (snow)
Stream/Surface runoff
Most water returns to the sea in the form of rivers
Evapotranspiration
Evaporation of moisture from vegitation
Groundwater Flow
Some water returns to the sea as groundwater through soil and rocks. Eg through Limestone.
Infiltration
When rainfall seeps into soil.
Percolation
When water seeps down through/into rocks.
Throughflow
When water travels downwards through soil back into the sea.
Groundwater Zone
Storage area for water which is slowly released back to the sea via springs and rivers.
Interception
When precipitation is stopped from falling to the surface by leaves or dense forests.
