Flashcards in Rivers Deck (25)
What is precipitation?
Water falls to the ground as this. Can be in the form of rain, snow, sleet or hail.
What is surface water?
Streams and rivers. It finds its way to the sea.
What is Ground water?
Water that vey slowly passes through the soil and rocks as groundwater flow.
Vegetation take water up through roots in order to grow. Some water returns to the air via leaves
Earth's water is passed up into the atmosphere. Liquid water is turned into vapour as it passes through the air.
In order, what are the processes of the water cycle?
Evaporation, condensation, precipitation, surface water, ground water and transpiration
When vapour from the air condenses to water droplets to form clouds
Water moving over the surface in eg. a river or to a river
Water soaks into soil
Water flows through soil to eg. a river
Water runs into underlying rock
Ground Water flow
Water flows through rock towards eg. a river
Roots from plants and trees suck up water from the soil to grow to intercept the water

3 parts of a river
The force of water against the bed and banks.
The bed and the banks are worn down by the river's load. The river throws these particles against the bed and banks, sometimes at high velocity.
Material (the load) carried by the river bump into each other and so are smoothed and broken into smaller particles.
