What is Canada's largest landform?
The Great Canadian Shield
As water flows across the surface of Earth this form of erosion happens.
Water erosion
What are the 3 types of plate boundaries?
divergent, convergent and transform
What is a landform?
The natural features that make up Earth’s surface
Area of low land between areas of higher land.
Valley
During the ice ages, ice sheets, or glaciers, slowly moved across Earth’s surface, scraping the top layers of rock causing this form of erosion.
Ice erosion
When 2 plates collide, forcing one to lift up over time and form mountains.
Convergent
Records shaking in the ground.
Seismograph
What are two types of mountains?
Fold and volcanic
Where the land surface is bare, the wind picks up weathered particles and carries them along causes this form of erosion.
Wind erosion
When 2 plate boundaries grind against each other usually causing earthquakes
Transform
Measures the magnitude of an earthquake.
Richter scale
Low, flat land.
Plains
Humans change landforms for these 3 main reasons...
Creating living spaces, meeting basic needs and mining.
When 2 plate boundaries pull away from each other and magma flows through to the surface often creating volcanoes or volcanic mountains.
Divergent
the outer, solid layer of Earth made up of moving plates.
Lithosphere
Large areas of mainly flat land found at high elevations
Plateau
Does Ms.D believe in you?
Absolutely!!!
The theory that Earth’s crust is made up of several rigid pieces, or plates, that are pushed by forces inside the planet.
Plate tectonics
soft weak layer under the lithosphere upon which the tectonic plates move.
Asthenosphere
