Approximately how many tectonic plates are there?
20
On which layer of the Earth do we live?
The Crust
What is the oldest landform region in Canada?
The Canadian Shield
The Earth is estimated to be roughly how old?
4.6 Billion Years Old
What are the three types of plate boundaries/movements?
Convergent
Divergent
Transform
What are the four layers of the earth from the outside in?
Crust
Mantle
Outer Core
Inner Core
In what landform region is the nation's capital located?
St. Lawrence Lowlands
What are the four layers of the earth?
Crust, Mantle, Outer Core, Inner Core
What are Wegener's Four Proofs for the existence of Pangea?
Jigsaw Fit Between Continents
Same Types of Fossils
Mountains of Similar Age and Structure
Evidence of Ice Where There Shouldn't Be
What are the three types of Rock?
Igneous Rock
Metamorphic Rock
Sedimentary Kid
Which landform region has the most productive farming, also known as the "breadbasket" of Canada?
Interior Plains
What type of Volcano builds upward in a steep form, combining Ash and Lava
Strato/Composite Volcano
Why did scientists accept the theory of Plate Tectonics to be true but previous scientists hadn't accepted the theory of Continental drift?
Wegener could not explain what force was powerful enough to move continents. Plate tectonics explained that movement was caused by heat from the lower layers of the earth.
List the four geologic eras in order, starting with the oldest.
Precambrian
Paleozoic
Mesozoic
Cenozoic
Which of Canada's Landform Regions contains the most volcanoes?
Western Cordillera
List one result of Erosion and one result of Glacial Deposition
U Shaped Valleys
Eskers, Drumlins
What are the three types of convergent boundaries and what type of landform do they create?
Continental to Continental = Mountains
Continental to Oceanic = Volcanoes
Oceanic to Oceanic = Underwater Volcanoes
