Section One - Rivers Flashcards
What is infiltration?
When water is soaked into soil.
What is the hydrological cycle?
It’s the movement of water, it shows how water moves around in flows, storages and outputs.
What is percolation?
When water moves vertically through soil and rock.
What is through flow?
When water in soil flows downhill.
What is groundwater flow?
When water in rock flows downhill.
What is surface run off?
When water flows overground.
What is channel flow?
When water flows in a river.
Name the 6 flows.
Percolation Infiltration Through flow Groundwater flow Surface run off Channel flow
What is channel storage?
When water is held in a river.
What is groundwater storage?
When water is stored underground.
What is interception?
When water lands on plants leaves ect.
What is surface storage?
When water is held in lakes.
Name the 4 storages.
Groundwater storage
Interception
Surface storage
Channel storage
What is a drainage basin?
An area that is drained by a river. These are split up by watersheds.
Name an input of a drainage basin.
Precipitation.
Name 3 outputs of a drainage basin.
Evaporation
Transpiration
River flow into the sea.
What’s a tributary?
A small river.
What’s a source?
Where the river starts.
What’s a confluence?
Where 2 rivers meet.
What’s a mouth?
Where the river meets the sea or lake.
What’s mechanical weather and give an example?
When rock is broken down without changing the chemical composition. An example is freeze thaw weathering.
What is chemical weathering and give an example?
When rock is broken down by changing it’s chemical composition. An example is carbonation weathering.
What does a rivers long profile show?
The gradient of the river at different points, the rivers course as the source and mouth of a river.
What’s the cross profile of a river show?
The width and depth of the over and the land around it (valley sides).
