What was the name of the Supercontinent of all our continents combined?
Pangea
100
Interior plains

How are sedimentary rocks formed?
Settling of dirt & fossils, pressed into stone.:max_bytes(150000):strip_icc()/Layers_of_sedimentary_rock_in_Makhtesh_Ramon_50754-3a40a0968fea41718b339824873ef3e9.jpg)

Explain Latitude's impact on climate?
The closer to the equator the warmer, the closer to the poles the cooler.
100
What is the difference between magma and lava?
magma is below the earth's surface and lava is above it
200
What did Alfred Wegener discover?
Continental Drift Theory & 4 Proofs
200
Which landform region has the oldest mountains in Canada?
The Appalachian region.
200
What are the three types of plate boundaries?
Convergent, divergent, transforming.
200
What does each letter in LOWERN stand for?
Latitude, Ocean Currents, Winds, Elevation, Relief, Nearness to Water
200
How are Wegener & Wilson's theories connected?
Wegener = WHAT (are plates are moving)
Wilson = WHY (why our plates move & drift)
300
What is convection? Why does it affect our continents?
Convection = hot liquid rises, cold liquid cools.
Hot liquid rock under the earth rises up & falls in a circular pattern; this is what pushes our continental plates around.
300
What landform region is highlighted here?
The Hudson Bay Lowlands.
300
Is this mountain young or old? Why?
This is an old mountain - its top is not pointy, it is rounded because of erosion.
300
Why does being "near water" affect climate? (keyword)
Moderating effect - water makes the temperature around not too hot not too cold.
300
What are the four eras of geologic time?
Precambrian, Palaeozoic, mesozoic, cenozoic
400
List the structure of the Earth (inside out)
1. Inner Core (solid)
2. Outer Core (Liquid)
3. Mantle
4. Crust (bonus: lithosphere underneath upper crust)
400
What landform region has rocks scraped bare by the glaciers in Canada?
The Canadian Shield
400
How did glaciers help built the Shield & our lowlands?
Glaciers scraped dirt off our Shield to expose rock; deposited it onto our lowlands (Prairies, Great Lakes).
400
Why is it colder at the TOP of a mountain and warmer at the BOTTOM? (2 keywords)
There is less PRESSURE in the air at higher ELEVATIONS. Less pressure = more spaces for air molecules to spread out and cool down, which is why it is colder than at the bottom.
400
Name the VEGETATION region in Canada that is cold, has low-heights of grass, and lichens.
The Tundra.
500
Name the 4 Proofs of Continental Drift
1. Jigsaw (South America & Africa)
2. Fossils (South America & Africa)
3. Mountains (Same in Newfoundland as Ireland)
4. Natural Gases (same in Antarctica & Africa/Australia)
500
What landform region do we live in?
The Great Lakes and St Lawrence Lowlands
500
What is it called when one plate goes under another? (2 keywords)
Subduction - heavier plate
Uplift - lighter plate
500
Describe relief and how it impacts climate? (2 keywords)
mountains act as a barrier to air masses. The windward side of the mountain is warm and wet (rainy), and the leeward side is cool and dry.

Which Era was the "Age of Dinosaurs"?
Mesozoic
