Flashcards
IGCSE Geography Hydrological Cycle transfers
Cards in this deck (10)
- 1EvaporationWater is converted from liquid form into a gas (water vapour) on the SURFACES of lakes etc due to the heat of the sun.
- 2TranspirationWhere plants TAKE UP liquid water from the SOIL (with their roots) and "breathe" it into the ATMOSPHERE as water vapour
- 3InterceptionWhen trees and plants OBSTRUCT (intercept) the DOWNWARD movement of precipitation by STORING some of the water on their LEAVES
- 4CondensationWhere the ATOMOSPHERE cools and water vapour changes into a liquid. This liquid takes the form of water droplets that appear in the atmosphere as CLOUDS.
- 5PrecipitationThe transfer of water in ANY FORM from the ATMOSPHERE to the land or sea SURFACE. This can be in the form of rain, hail or snow.
- 6Overland flowWhere precipitation hits the ground and MOVES UNDER GRAVITY and eventually enters a stream, river or lake. This is also known as surface run off.
- 7Infiltration and percolationThis is the transfer of water downwards through the soil and rock into the AQUIFER or UNDERGROUND STORE
Infiltration- water moving downwards through the soil
Percolation- water moving through rocks and into the aquifer/u.g. store - 8ThroughflowThis takes place between the ground surface and the top of the groundwater store. Under the influence of GRAVITY, water moves slowly THROUGH THE SOIL until it reaches a stream or river.
(movement of water horizontally under land surface but over aquifer due to gravity) - 9Groundwater flowThis takes place in the AQUIFER and is the UNDERGROUND transfer of water to rivers, lakes and the sea
- 10EvapotranspirationLOSS of moisture DIRECTLY from rivers/lakes (evaporation) and vegetation (transpiration)
