Weathering, Erosion and Deposition
When physical, chemical or biological forces break down rocks
What is weathering?
The area of land that drains into one main lake or river
What is a watershed?
A slow-moving piece of ice and snow
What is a glacier?
The part of the Earth's surface that has ice
What is the cryosphere?
The average weather measured over a long period of time
What is climate?
What is erosion?
What is safe drinking water through floodplains
How a glacier forms
What is snowflakes accumulate and gradually become grains, then ice crystals and finally ice; over time, snow particles change from flakes to grains; the grains are compacted by the weight of more layers of snow
How glaciers shape and change landforms
Streams of water that move within a larger body of water
What are currents?
What is a flood plain?
What are moraines?
Form when parts of a glacier melt, the meltwater flows in tunnels under the ice which releases sand and gravel in the pattern of a winding river
What are eskers?
What currents can be caused by
What is wind, temperature and salinity differences and earth's rotation?
This causes chemical weathering to occur - when chemicals get into the clouds and mix
What is acid rain?
What is an estuary?
Small hills with a distinctive tear shape
What is a drumlin?
The largest type of glacier
What is an ice sheet?
This is the reason water takes so long to heat up or cool
What is water's high specific heat capacity?
How a stream shapes the land around it
What is when the water weathers and erodes away the rocks so that it can continue flowing?
The highest land on the continent determines the direction that a watershed drains
What is the Continental Divide?
1. When glaciers melt faster than it flows
2. When glaciers flow faster than it melts
What is
1. Retreating glacier
2. Advancing glacier
The different forms of glaciers
What are ice caps, ice sheets, lake and river ice, sea ice, icebergs and ice shelves
If currents start near the equator, they have this type of water
What is warm water?
