Major stores Flashcards
What are the four major water stores? COAT
- Cryospheric Water
- Oceanic Water
- Atmospheric Water
- Terrestrial Water
What 5 components does the cryospheric store contain?
- Sea Ice
- Permafrost
- Ice caps
- Ice sheets
5.Alpine Glaciers
When melted what store will not have an effect on rising the sea level?
Sea Ice
Why is it important for there to be an abundance of sea ice?
Sea ice reflects a lot of solar energy back into space, if it is not there it will absorb the heat and contribute to global warming.
True or false: Ice caps are based on land.
True
Give an example of a large Ice sheet.
Greenland
What 5 components does the terrestrial store contain?
- Surface Water
- Ground Water
- Water Table
- Soil Water
- Biological Water
How is water stored in the rock underground?
In pore spaces of the rock
What is soil water?
Water held together with air, in the unsaturated upper layers of soil.
What level of rock is the Water table found?
The upper level of saturated rock.
What is biological water?
Makes up the water stored in plants
What are the three main transfers of water in the atmosphere?
- Evaporation
- Condensation
- Precipitation
Through what process is water vapour returned back to the atmosphere?
Transpiration
Why is the ocean becoming increasingly acidic?
More c02 is being absorbed from the atmosphere- forming carbonic acid
What are clouds?
Visible mass of water droplets/ice crystals suspended in the atmosphere.
What are the clouds the result of?
Air in lower atmosphere becoming saturated as it cools.
Why is atmospheric water important to life?
Because it absorbs, reflects and scatters incoming solar radiation, keeping the atmosphere at a temperature that can maintain life.
How are ice caps different from ice sheets?
Ice caps are smaller than 50,000km squared
Ice sheets are greater than 50,000km squared
Where do you find Alpine glaciers
In deep valleys and upland hollows.
Define an aquifer?
Water that is stored underground in the pore spaces of rock.
Outline flows within the water cycle operating on a hill slope.
Surface runoff occurs when water runs directly over the ground.
This may occur if the soil is saturated (or flow over impermeable surfaces).
* Infiltration occurs when the water moves from the surface and then down through the soil horizons, until it reaches the groundwater or an impermeable layer in the soil
* Throughflow occurs when, under the force of gravity, water moves downslope through the soil until it reaches a water body. This movement is usually very slow due to the frictional effect of the soil particles.
* Groundwater flow is the movement of water through permeable rock under the force of gravity. This is the slowest flow of water on a hillslope
. Other types of flow may also be considered e.g. percolation, stemflow
Where are the typical stores of water within the lithosphere?
Groundwater, lakes and marshland
Where are the typical stores of water within the lithosphere?
Groundwater, lakes and marshland
What does impermeable rock prevent?
Percolation
