A-Level - Water Cycle Glossary: Flashcards
What are some Examples Of Local Water Stores?
1) Interception,
2) Vegetation Storage,
3) Surface Storage,
4) Soil Moisture,
5) Groundwater Storage,
6) River Channel.
What is Interception?
Raindrops being prevented from falling directly onto the ground, instead hitting the leaves from vegetation - short term store.
What is Vegetation Storage?
Moisture within vegetation at any one time.
What is Surface Storage?
Water stored in puddles, ponds, lakes etc - variable term store.
What is Soil Moisture?
Water stored in the soil which is utilised by plants - mid term store.
What is Groundwater Storage?
Water that is stored in the pore spaces of rock - long term store.
What is River Channel?
Water that is stored in a river - short term store.
What are the Four Global Water Stores?
1) Hydrosphere,
2) Lithosphere,
3) Cryosphere,
4) Atmosphere.
What is the Hydrosphere?
All the Earth’s water in the world: oceans, lakes, seas, rivers etc.
What is the Lithosphere?
Water stored in the crust and upper mantle as a liquid: all infiltrated soil, groundwater, surface water etc.
What is the Cryosphere?
The global water volume locked up within a frozen state as snow and ice.
What is the Atmosphere?
Water within the atmosphere in a gaseous state - water vapour.
What are some Primary Water Processes?
1) Precipitation,
2) Evaporation,
3) Transpiration,
4) Evapotranspiration,
5) Surface Runoff.
What is Precipitation?
Any water that falls to the surface of the Earth from the atmosphere.
What is Convectional Precipitation?
Solar radiation heating the air above the ground, causing it to rise, cool, and condense forming precipitation.
What is Frontal Precipitation?
Where air masses of different temperatures meet at a front, one mass will be forced over another, causing precipitation beneath the front.
What is Relief Precipitation?
Precipitation caused when air masses are forced to rise over high land, determined by the relief / morphology of the land.
What is Depression?
A system of low pressure, with front of precipitation where low and high pressure air masses meet.
What is Evaporation?
The process by which water changes from a liquid to a gas or vapour.
What is Transpiration?
The process by which water evaporates through the stomata in a plants leaves.
What is Evapotranspiration?
The combined total moisture transferred from the Earth to the atmosphere, through evaporation and transpiration.
What is Condensation?
The process by which water vapour in the air is changed in liquid water - as it loses energy to the surroundings.
