geography rivers

condensation

water vapor (gas) turning into water droplets (liquid)

confluence

the point where two rivers join

drainage basin

the area of land drained by a river

erosion

wearing away of rock by a moving force (there are 4 types)

evaporation

water (liquid) turning into a water vapor (gas)

infiltration

water entering the soil/rock

precipitation

any form of water falling to the ground

surface run-off

water flowing over the land

tributary

A smaller river flowing into a larger one

weathering

breakdown of rock

abrasion

type of erosion where sediment in the water scrapes away at rock

attrition

type of erosion where the sediment carried by a river get bashed into smaller rounder pieces

corrosion

type of erosion where chemicals in the water dissolves rock

deposition

when the rivers

when the river drops sediment because of low energy

gradient

angle of the land which affects the speed of the river flow

hydraulic action

type of erosion where the force of water wears away rock

river long profile

side on view of a river’s course split into upper, middle and lower

river velocity

the speed of the river flow

the load

sediment carried by a river from large boulders to tiny grains of silt

transportation

movement of sediment by a river

delta

land form made by river sediment deposited in the sea at the mouth of the river

estuary

where the river water meets the sea water

floodplain

flat land either side of a river

gorge

steep sided valley formed by the movement and erosion of a waterfall

levee

the raised banks of the river channel

meander

bend in a river

ox bow lake

meander that has been cut off from the main river channel

river cliff

outside of a meander
