Flashcards in Ice And Runoff Deck (20):
0

Thick sheets of ice that form in the polar regions and spreads over thousands of kilometers in all directions

Continental glaciers

1

What would happen if a glacier began to melt

A flood could occur

2

Elevation in which some snow from the winter that lasts through the summer and doesn't melt

Snow line

3

Boulders moved by glaciers from one place to another dropped from the melting ice

Erratics

4

Large chunks of ice

Icebergs

5

What lakes form in

Depressions or kettles gouged by ice chunks

6

Ways to form lakes and ponds

-glaciers form a basin
-volcanoes and earthquakes create holes
-people build dams
-meteors create craters

7

Factors that create runoff

-vegetation(limits amount of runoff and speed)
-landscape
-amount of rain

8

Similarity between pore space in ground and sponge

Both have air packets that absorb water

9

Infiltration capacity

Maximum rate at which soil can absorb water

10

Infiltration capacity is dependent on...

soils porosity, permeability, surface conditions, and moisture content

11

Water table

Level at which the groundwater is at its capacity

12

Environment that would create more surface runoff

Area that is muddy from frequent rain and melting snow

13

Land area in which surface runoff drains into a river or a system of rivers and streams

Watershed

14

Prevents floods and water shortages by controlling amount of water that flows into streams and rivers

Watershed

15

What would be a better source of freshwater a fast moving river or a river that flows slowly

A slow moving river because the sediment and bacteria will mostly be at the bottom

16

Bodies of standing water

Ponds and lakes

17

Difference between lake and pond

Pond is shallow enough for sunlight and plants to grow sun can't reach the bottom of a lake

18

Artificial lake

Reservoir

19

Purpose of reservoir

Stores water to drink, useful for recreation, and good in case of emergencies
