Living things (In your own words, what you think?)

• What does it mean to be alive?• How do YOU know if something is alive?• What are three traits shared by all living

things?

What are Glaciers?

• Large body of ice and snow that has been built up over centuries.

• Glaciers can move at a rate of 2 cm/yr under their own weight and gravity

• They move and destroy everything in their path, bulldozing trees, rock, etc…

• They can wear down Mountains, turning them into hills, and flat land.

• They can carve valleys out of rock

Page 7: Living things (In your own words, what you think?)

Water Erosion

• Wears away the surface of earth using rivers and other sources of surface water.

• Destroys landscapes and houses due to massive rainfall.

• Water can pick up minerals and drop them off at another location.

• Water can dissolve minerals

Compare and Contrast

• Mountains of ice and snow

• Slow moving•Wears down Mountains

• Fast moving• Wears down the

surface of earth• Dissolves minerals

• Water• Cause erosion•Change surface of

earth

Glacial versus Water Erosion

Glaciers• Large Mountains of snow

and ice that build up over time.

• Slow moving under its own weight

• Acts as a bulldozer, moving down rocks, trees, picking up sediment and scraping and polishing land as it moves

Water• Water falls to earth during

rain.• Fast moving water moves

down slope, carries away sediments

• Carves out the land• Major force of erosion• Water dissolves particles

and deposits them elsewhere

Page 11: Living things (In your own words, what you think?)

ValleyV-shaped

• Found near the source of rivers• Formed from fast moving

water dissolving and breaking down rock and minerals along its path.

U-shaped

• Results when a river valley has been further eroded by a glacier

• The glacier over deepens a v shaped valley, polishing and reshaping the contour of the walls
