a collection of channels that make up the drainage basin
the route rivers flow
where the river flows into the sea or a lake
sum of all the lengths of the river + area of the drainage basin
7. What is ground water flow?
this is the movement of water sideways through the soil
where the precipitation flows along the stems of a plant to the ground
where the water is evaporated straight from the ground or from the sea
where the precipitation is not intercepted but falls straight to the ground
8. What is the watershed?
the boundary of a drainage basin where there is a higher area of land, that separates one drainage basin from another
a connection of channels that make up the drainage basin
where two rivers join
the route the river flows
9. What is through fall?
slow movement of water through the ground
where precipitation is not intercepted but falls straight to the ground
where rivers enter through the ground
where water vapour falls through the clouds
10. What can the drainage basin also be called?
river area
The catchment area
the drainage base
the basin
11. What is over land flow?
this happens when either the soil is impermeable or saturated and the water flows over the top of it
where the water goes up through the plants and is released into the air through the leaves
slow movement of water through the ground
water in any form that comes from the clouds (e.g. - snow, rain, sleet, hail)
12. What is infiltration?
Water lying on the soil
The process where water on the ground surface enters the soil
Water lying on trees and plants
The process where water seeps through soil into rock
13. What is interception?
where plants, trees or buildings collect the precipitation
when the precipitation flows through the plant into the ground
when the ground intercepts the water entering the soil
where water is moved sideways through the soil
14. What is condensation?
The process of water vapour changing to a liquid
Water molecules rising
The process of liquid changing to a vapour
Water seeping into the ground
15. What is precipitation?
Water that reaches the surface of the earth but does not infiltrate the soil
Process where water seeps into the ground
Water being released from clouds as rain, snow, sleet or hail
When water molecules rise into the atmosphere as vapour
16. What is a convection current?
When heat is lost
When radiant particles cause the molecules to have more energy and rise
When warm/humid air rises and cooler air flows downwards because as warmer air rises, water vapour looses its energy causing it to change state
When energy from the sun heats water molecules, causing them to become so active that some of them rise into the atmosphere as vapour
17. What is the drainage basin?
A space full of water
An area of land drained by the river and it's tributaries
A place where rivers flow
Where lots of rivers join
18. What is percolation?
Water moving from the ground to the soil
Where water moves downwards through soil
Where plants, trees or buildings collect precipitation
When precipitation is not intercepted
19. What is evapotranspiration?
When leaves release water into the atmosphere
where water vapour changes to a liquid
the process by which water is transferred from the land to the atmosphere by evaporation from the soil and other surfaces and by transpiration from plants.
