Erosion
Erosion breaks down landforms, but it also does this:
It creates landforms.
When glaciers move, they push these materials in front of them
Rocks and boulders.
Water can move small pieces of material to a new ____________
What is location?
True or False: Plant roots help to anchor soil and sand dunes in one place
True
Humans change the flow of water by doing this:
What is building dams or diverting rivers?
The wearing away of Earth’s surface by wind, water, or glacial action. It moves materials from one place to another.
What is Erosion?
When glaciers melt or recede, the rocks get ____________ at the front edge
What is deposited?
When moving water (i.e. rivers) is flowing fast, it can carry ___________ __________
Eroded material (like rocks, sand, etc.)
True or False: Wind cannot carry particles very far.
False
People change land, and even create land by doing this:
What is landfill?
A natural force that breaks down rock into small particles
What is Weathering
When a glacier deposits rocks at the edges and they form a ridge
What is a moraine?
When the water slows down near the larger bodies of water (i.e. lakes and oceans), it drops the eroded material it's carrying, which builds up on the bottom of the lake or sea. When the tectonic plate pushes this up above the surface of the water, it forms a landform called:
What is a plain?
Particles carried by wind will be deposited when the wind dies down, creating ___________ ___________
What are sand dunes?
People create major erosion issues like landslides by doing this:
What is cutting down trees?
Acid in water can dissolve rock into particles, like sand.
What is Chemical Action?
Glacial erosion is so powerful that it can carve out deep landforms called
What are valleys?
If the sedimentary plain gets pushed up even higher, it becomes:
What is a plateau?
If the wind is blowing fast, it can pick up more and bigger particles - even large items like cars, etc. and moving them to a new location. What are these types of winds called?
What are tornadoes, hurricanes, etc.?
People change the surface of the land for these reasons:
What is building homes, growing crops or raising livestock, or extracting minerals?
When wind and water break down and disintegrate rocks
What is Physical Action?
This feature forms when the level of the sea rises, filling a valley once cut by a glacier
What is a Fjord?
Water can carve rock, forming deep landforms
What are valleys
Over time, wind can even carve ________ and erode ___________
What are rocks and mountains?
One of the most extreme types of human-caused erosion is:
What is mountaintop removal mining?
