Water Cycle
When water falls from clouds as rain, snow, hail, or sleet.
Precipitation
Name a consequence of flooding
Property damage
Loss of life
Pollution
Erosion
Health issues
River (fast flowing water) wears away the river bank from underneath
Hydraulic action
A bend in a river
Meander
What is the longest river in the world?
Nile
When the sun heats water, turning it into water vapor (gas) and rising into the air.
Evaporation
a large concrete barrier built across a river to stop its flow
Dam
Rocks carried along by the river wear down the river bed and banks (friction)
Abrasion
A stream or river that flows into a larger river
Tributary
What is the largest river in the world?
When water vapor cools and turns back into tiny water droplets, forming clouds.
Condensation
a generally flat area of land adjacent to a river, stream, or lake that experiences periodic or occasional flooding
Floodplain
Rocks being carried by the river smash together and break into smaller rocks
Attrition
projecting, alternating ridges of hard rock that extend from opposite sides of a youthful, V-shaped river valley
Interlocking spur
Describe the difference between the longest and the largest river?
The longest river has the most length. The largest river has the most volume of water.
When rainwater moves underground through the soil to rivers, lakes and the ocean
Throughflow
Name four ways that humans can manage flooding
Dams
Embankments
Flood warnings
Planting trees
A transportation process where large boulders and rocks are rolled along the river bed.
Traction
These embankments or ridges form when a river overflows, losing velocity and depositing coarser, heavier sediment first near the banks.
Levee
What is the largest river in North America?
Mississippi River
When plants release water vapor into the air through their leaves.
Transpiration
Name five causes of flooding
Impermeable rock
Deforestation
Urbanization
Steep slopes
Very dry soil
A river process of transportation where small pebbles and stones bounced along the river bed.
Saltation
The point where two or more rivers join together to form a single, larger river.
Confluence
What is the longest river in Europe?
The Volga River
