Rivers Flashcards
Precipitation
Water falling from the clouds. eg - rain, hail, snow.
Evaporation
the water from the ocean turns into a gas and goes up into the air.
Condensation
The gas turns back into water as a small droplet which form a white, grey or black cloud.
Surface runoff
When the rain, snow or hail runs down back into the source of water.
Ground water
The rain, snow or hail is absorbed by plants and goes through the ground back to the source of water.
Transpiration
When water is taken from plants during evaporation.
Stage 1 of water fall
- Hard and soft rock
River process (4 processes) Erosion
- Hydraulic action (force to move the rocks)
- Abrasion (Sandpaper across the bed and banks of the river)
- Attrition (2 rocks collide into pebbles)
- Dissolve (turns into solution and joins the river flow).
Traction (transport)
When the bolder (rocks) roll across the bed or the river and hit against each other.
Salutation (transport)
The Rocks/pebbles bounce across the river and collide.
Suspension (transport)
The tiny rocks float along the river.
Solution (transport)
The rocks dissolve and become minerals in the river.
Drainage basin
The area where rain falls into.
Source
Where the water comes from.
Tributaries
The break off from the channel.
Confluence
The merge between two rives in one river.
Mouth
Where the river ends to the sea.
Stage 2 of waterfall
- Soft rock erodes
Stage 3 of waterfall
- Notch develops
Stage 4 of waterfall
- Erosion (hydraulic action/abrasion
