Plate Tectonics & Pangaea
What is Continental Drift?
The theory that Earth’s plates are moving.
What is Topography?
The natural features of the Earth’s surface.
What is Geology?
This term refers to the types and history of rocks in an area.
What is the Canadian Shield?
The major Canadian landform region that contains the oldest rock in Canada.
What is the Crust?
The thinnest, outermost layer of Earth, where all continents and oceans are found.
Who is Alfred Wegener?
The German scientist who proposed the idea of Pangaea.
What is Weathering?
The wearing down of the Earth's surface from exposure to the atmosphere.
What is Elevation?
The height of a landform measured from sea level.
What is the Appalachian Mountains region?
This landform region, covering most of Atlantic Canada, is home to the Appalachian Mountains.
What is the Mantle?
This is the layer beneath the crust and is made of hot, dense, semi-solid rock.
What is Pangaea?
The name of the ancient supercontinent where all the continents were once joined.
What is Deposition?
The process where eroded materials add a new shape to the land.
What is Gradient?
This refers to the steepness of slopes.
What are the Interior Plains?
This landform region covers most of Alberta, Saskatchewan, and Manitoba and has good soil for growing wheat.
What is the Outer Core?
This is the layer of liquid iron and nickel that creates Earth's magnetic field.
What is Plate Tectonics?
The theory that explains how the interaction of Earth's plates produces mountains, trenches, earthquakes, and volcanoes.
What is Relief?
The difference in elevation between points on the Earth's surface.
What is Landscape?
The shape of the land together with its cover of vegetation, water, ice, and rock.
What are the Innuitian Mountains?
This landform region is in the Far North and is too cold for trees to survive.
What is the Inner Core?
The hottest, most dense layer at the very center of Earth, made of solid iron and nickel.
What is a Subduction Zone?
An area of the Earth’s crust where one plate slides beneath another.
What type of current causes Earth's plates to move?
Convection Currents
What are what they eat, how they earn a living, who they do business with, or other factors of their daily life?
The four ways landscape can affect people’s lives.
What are the Great Lakes-St. Lawrence Lowlands?
This region has fertile soil and includes parts of Ontario and Quebec, near the bodies of water it's named for.
What is the Lithosphere?
The rigid layer that includes both the crust and the uppermost part of the mantle, which is broken into tectonic plates.
