Ice And Runoff Flashcards
What would happen if a glacier began to melt
A flood could occur
Thick sheets of ice that form in the polar regions and spreads over thousands of kilometers in all directions
Continental glaciers
Elevation in which some snow from the winter that lasts through the summer and doesn’t melt
Snow line
Boulders moved by glaciers from one place to another dropped from the melting ice
Erratics
Large chunks of ice
Icebergs
What lakes form in
Depressions or kettles gouged by ice chunks
Ways to form lakes and ponds
- glaciers form a basin
- volcanoes and earthquakes create holes
- people build dams
- meteors create craters
Factors that create runoff
- vegetation(limits amount of runoff and speed)
- landscape
- amount of rain
Similarity between pore space in ground and sponge
Both have air packets that absorb water
Infiltration capacity
Maximum rate at which soil can absorb water
Infiltration capacity is dependent on…
soils porosity, permeability, surface conditions, and moisture content
Water table
Level at which the groundwater is at its capacity
Environment that would create more surface runoff
Area that is muddy from frequent rain and melting snow
Land area in which surface runoff drains into a river or a system of rivers and streams
Watershed
Prevents floods and water shortages by controlling amount of water that flows into streams and rivers
Watershed
