Landforms and Tectonic Plates

Question 1

Who proposed the idea of Pangaea?

Answer 1

Alfred Wegner

Question 2

When did Pangaea drift apart?

Answer 2

300 million years ago

Question 3

Who helped explain Pangaea through Plate Tectonics?

Answer 3

J Wilson

Question 4

Explain Plate Tectonics

Answer 4

Earth’s crust is broken up into 20 plates of solid rock floating on a layer of magma in the earth’s mantle

Question 5

Explain Convection Currents in Plate Tectonics

Answer 5

Convection Currects in the mantle spread the ocean crust, creating volcanos, mountains, and new crust

Question 6

What are Convergent Tectonic Plates?

Answer 6

Convergent Tectonic Plates collide and make mountains

Question 7

What are Divergent Tectonic Plates?

Answer 7

Divergent Tectonic Plates pull apart and expand sea floor

Question 8

What are Transform Tectonic Plates?

Answer 8

Transform Tectonic Plates slide past eachother and make no obvious landforms

Question 9

What is Glaciation?

Answer 9

Glaciation is the process of ice advancing and covering large areas of land

Question 10

What originally covered most of Canada?

Answer 10

Glaciers originally covered most of Canada

Question 11

What did Glaciers do to Canada?

Answer 11

Glaciers altered landforms through erosion and deposition

Question 12

When were Glaciers last in Ontario?

Answer 12

10,000 years ago

Question 13

What is the Canadian Shield?

Answer 13

The original and oldest landform in North America. Everything comes from this landform.

Question 14

What are Lowlands?

Answer 14

They are the landforms with the lowest elevation, and are the flatter areas surrounding the shield. They are made of sediments from the Canadian Shield.

Question 15

What are Highlands?

Answer 15

They are mountains on the edge of the country formed through Plate Collision

Question 16

Explain the climate factor of Latitude

Answer 16

The further from the equator, the colder it gets.

Question 17

Explain the climate factor of Ocean Currents

Answer 17

Warm currents make places warmer and wetter. Cold currents make places colder and drier

Question 18

What happens when cold and warm ocean currents come together?

Answer 18

Fog

Question 19

Explain the climate factor of Elevation

Answer 19

The higher the elevation is, the colder it gets

Question 20

Explain the climate factor of Relief

Answer 20

Moist air rises through the windward slope, expands, cools and causes rain.

Question 21

What happens to the other side of mountains after Relief?

Answer 21

They remain dry.

Question 22

Explain the climate factor of being near water?

Answer 22

Large water bodies have a moderating effect; Maritime = less extreme, cooler summers. More percipitation | Continental = more extreme, warmer summers. Less percipitation

Question 23

What is temperature calculated in?

Answer 23

Degrees celcius

Question 24

What is precipitation calculated in?

Answer 24

Millimeters

Question 25

How do you calculate Average Annual Temperature?

Answer 25

Adding the twelve average temperatures, and dividing by twelve.

Question 26

How do you calculate Temperature Range?

Answer 26

Subtracting the difference between the maximum and minimum temp. Less than 25°C = Maritime | More than 25°C = Continental

Question 27

How do you calculate Total Precipitation?

Answer 27

Adding the twelve monthly precipitation totals. Maritime = more than 1000 mm | Continental = less than 1000 mm

Question 28

How do you calculate Seasonal Distribution of Precipitation?

Answer 28

Adding the precipitation in the winter months and compare to the precipitation in winter months. Winter max. = Maritime | Summer max. = Continental

Question 29

What are the "Winter Months"?

Answer 29

October to March

Question 30

What are the "Summer Months"?

Answer 30

April to September
