Rivers Flashcards
What is the source of a river
The start
What is the mouth of a river
Where it meets a large body of water
What is a drainage basin?
A drainage basin is an area of land which feeds a river
Infiltration
water soaking into the soil
Transpiration
when water evaporates from plants
Throughflow
Water that is soaked into the soil and flows towards a river
Surface run off
water that runs over the surface of the land
Groundwater flow
water that has socked into the rock layer and flows towards the river
Abrasion
the material being carried by the river hits the sides and bed of the channel, each impact breaking pieces off the bed and banks
Attrition
rocks and stones in the river bang against each other, chipping bits off so the rocks become more rounded and smaller
Hydraulic action
the force of the water pushes into cracks in the rock at the bed and banks
Corrosion
dissolved in the river water and carried away as dissolved material
What is a Hydrologist?
Hydrologists study how water flows across the land. They research and measure groundwater, and the drainage basin processes. It is Important that hydrologists study these processes to better understand river floods and droughts.
