LANDFORMS 101
This is a natural feature of the Earth’s surface.
What is a landform?
The four spheres of the Earth include Geosphere, ________, hydrosphere, and atmosphere.
What is the biosphere?
This region is made up of high, rugged mountains.
What is the Western Cordillera?
Earthquakes and volcanoes are examples of this kind of change to landforms.
What is natural change?
A network of a main river and all its connected streams.
What is a river system?
Mountains, valleys, and plateaus are examples of these.
What are types of landforms?
The sphere that includes all Earth's water.
What is the hydrosphere?
This region in central Canada is flat and good for farming.
What is the Interior Plains?
Mining and construction are examples of this kind of landform change.
What is human change?
An area where all water drains into one main river.
What is a drainage basin?
A cone-shaped landform formed when lava cools after an eruption.
What is a volcano?
The sphere that includes all living things
What is the biosphere?
Canada’s largest landform region, made of very old, hard rock.
What is the Canadian Shield?
The natural process that breaks down rock, soil and minerals into smaller pieces when they come into contact with the Earth's atmosphere.
What is weathering?
This is the most occurring drainage pattern. As the rivers flow over rocks a tree-like pattern will be created into the landforms.
What is dendritic drainage?
A large moving sheet of ice that can carve valleys as it moves.
What is a glacier?
This sphere is made of rocks, soil, minerals, and Earth’s crust.
What is the geosphere?
This region in eastern Canada has many hills, valleys, coastal cliffs, and older mountains.
What is the Appalachian region?
Moves these weathered pieces to a new location using natural things like ice, wind, water, and living organisms.
What is erosion?
This is a less common drainage pattern. If the river flows over both hard and soft rocks, it will create a rectangular drainage pattern with one main line and perpendicular lines that run off the main line.
What is trellis drainage?
This landform forms where a river drops sediment (dirt and other debris) into a larger body of water.
What is a delta?
A volcanic eruption affects all spheres. Ash in the air affects this one.
What is the atmosphere?
Mostly flat and low-lying land, Tundra, permafrost, and flat islands are found in this far-northern region.
What is the Arctic Lowlands?
The process of eroded soil and rock being transported by wind, water, ice or gravity and deposited in their new location.
What is deposition?
Usually caused by the friction of wind moving over water. This causes the water to move in a clockwise (Northern Hemisphere) or counterclockwise (Southern Hemisphere) spiral pattern.
What are surface currents?
