Rivers Flashcards
What is the hydrological cycle?
It is a continuous water system which shows how water moves around
What is evaporation?
When water is heated by the sun and turns into water vapour
What is transpiration?
The evaporation of water from plants (loss of moisture)
What is evapotranspiration?
Evaporation and transpiration happening together
Water vapour is moved inland by…
Winds
The water vapour condenses to form…
Clouds
What are transfers? E.g?
Water moving through the system
E.g surface run-off
What are outputs?
water lost when the river reaches the sea or through evaporation
What are stores?
When water is stored in lakes, rocks, soil or vegetation.
Name 3 transfers (there are 7)
- Infiltration
- Percolation
- Throughflow
- Groundwater flow
- Surface runoff
- Channel flow
Name 2 stores (there are 4)
- Channel storage
- Groundwater storage
- Interception storage
- Surface storage
What is infiltration?
When water soaks into the soil
What is percolation?
When water moves vertically down through soil and rock
What is throughflow?
When water in the soil flows downhill
What is groundwater flow?
Water going through rocks underground
What is surface run off?
Water flowing over a surface (impermeable)
What is channel flow?
The flow of water in a river
What is channel storage?
When water is held in a river
What is groundwater storage?
When water is stored underground in soil and rock.
A rock that stores water is called an…
E.g?
Aquifer
E.g chalk
What is interception storage?
When water lands on things like plant leaves and doesn’t hit the ground
What is surface storage?
When water is held in things like lakes, reservoirs and puddles
The water eventually ends up in the…
Sea
What is the one and only input?
Precipitation
