Question 4

Answer 4

First multi and single cell organisms

Precambrian shields

Question 5

What happened during the Paleozoic era

Answer 5

Age of amphibians and fish

Appalachians formed

Question 6

What happened during the Mesozoic era

Answer 6

Age of reptiles such as dinosaurs

Innuitian mountains formed

Question 7

What happened during the Cenozoic era

Answer 7

Age of mammals and humans

Formation of the Rocky Mountains

Question 8

Describe the Western Cordillera- location

Answer 8

western edge of Canada (British Columbia and Yukon

Question 9

Describe the western Cordillera- appearance

Answer 9

like a Great Wall, range after range of mountains separated by valleys of plateaus. Highest, youngest, most rugged mountains with steep slopes

Question 10

Describe the Western cordillera- rock types

Answer 10

rocky and Columbian mountains are sedimentary rocks. Coast mountains are a massive block of igneous rocks

Question 11

Describe the western cordillera- method of formation

Answer 11

Collision of the lighter North American plate and the heavier pacific plate which forced its way under, causing much folding, faulting and volcanic activity

Question 12

Describe the western cordillera- land use

Answer 12

Most people live in the farming and mining towns located in the river valleys and plateaus or on flat coastal locations. Tourists come for recreational activities (skiing, hiking) or to see the beautiful scenery (mountains, glaciers)

Question 13

What are the two conflicting forces wearing down and building up earth’s surface

Answer 13

Erosion and deposition

Wears down mountains and places the material lost somewhere else

Question 14

Define fiord

Answer 14

Long narrow inlet of the sea with steep sides fiords were created by glaciers that scraped out valleys when the glaciers melted the sea flooded the valleys

Question 15

Example of differential erosion and escarpment

Answer 15

Interior plains staircase like escarpments show the differential erosion

Question 16

Example of igneous rock, metamorphic rock, sedimentary rock

Answer 16

Granite, Gneiss, limestone

Question 17

Two types of glaciers and how the move

Answer 17

Alpine glaciers- move down valleys from higher elevations to lower elevations under the force of gravity
Continental glaciers- occupied greater areas of land and move under their own weight

Question 18

When did the last ice age began and end in Canada

Answer 18

The Ice Ages last glaciation activity begin about 100,000 years ago and ended about 6000 years ago

Question 19

Glaciers- Striations

Answer 19

Rocks frozen in the ice gauge out or scratches the bedrock as it moves tells us the path of the glaciers

Question 20

Glaciers- spillways

Answer 20

Huge volumes of glacial melt water carves out valleys now rivers pathways for rivers and therefore transportation route

Question 21

Glaciers- erratics

Answer 21

Large rocks picked up by glaciers and carried thousands of kilometers tells scientist from which region the glaciers moved and the landscaping

Question 22

Continental glaciers

Answer 22

On continents, distributes out from own weight

Question 23

Alpine glaciers

Answer 23

On mountains, slide down due to gravity
