Unit 2- Lithosphere Quest Flashcards

1
Q

Describe the features on the Earth’s surface in our area. How have people used them?

A

The Detroit River: The Detroit River connects Lake St.Clair to Lake Erie. It is used by many people. For example it is a major shipping Lane, recreational boats travel down the river and it is crossed daily to travel across Canadian and American borders. Fishing is also performed in the river.

Great Lakes: 5 massive lakes formed when the last ice age occurred. The great lakes are Lake Superior, Lake Erie, Lake Huron, Lake Ontario, Lake Michigan. The closest Great Lake to us is Lake Erie. Many people make use of Lake Erie. They boat, fish, swim, kayak, etc.

Fertile land: During the Ice Age fertile soil was brought to our region from Toronto. This gave us good land for agriculture. In our land we grow corn, vegetables, wheat, etc.

Lake St.Clair: Large lake in Essex county connected to the Detroit river. Used to boat, fish and collect resources such as water, etc.

Q

Why does the shield have ingenous rock.

A

The sheild has ingenous rock because of its long volcanic history. Since the shield is mostly rocky terrain because of volcanic activity in the far past, the rock is made of hot magma, cooling off and hardening into a rock.

Q

Definition of Igneous rock.

A

Igneous rock is one of the three main rock types, formed through cooling and solidification of magma or lava.

Q

Previous location of the materials that form the lowlands.

A

The materials were moved from more northern locations, to the lowlands, during the previous ice age. Also materials that form this region come from River erosion.

Q

Why are the lowlands made up of sedimentary rock rather than igneous rock.

A

The lowlands are made up of sedimentary rock rather than igneous rock because of the large bodies of water near by. (The Great Lakes)

Q

Definition of sedimentary rock.

Q

Give two different ways in which the ice affected the Great Lakes/ St.Lawrence Lowlands.

A

Formed the Great Lakes by eroding large holes in the earths surface and depositing water.

Removed fertile soil from different areas and deposited in this region. Also, River levels rises and flooding occurred in many areas within the region.

Q

Explain how the Niagara Escarpment was formed.

A

Niagara falls were formed because of cuesta. At the end of the last ice age, when the ice started to melt, large torrents of water from what are now the great lakes got liberated, and it wore away the rock layers and created the falls.

Q

What is a Cuesta?

A

The cuesta is a physical feature that has a steep cliff on one side, and a gentle dip or backslope on the other side. This landform occurs when erosion wears through a hard capping layer, and then rapidly grinds down the soft ground underneath.

Q

5 reasons why the Great Lakes/St.Lawrence Lowlands is so populated.

A
  1. Has good weather conditions for living in (4 seasons)
  2. Good transportation and trading waterways with the Great Lakes and St.Lawrence River.
  3. Many natural resources to live off of (Fresh water, fertile soil, etc.)
  4. A lot of manufacturing opportunities and job opportunities (industrial development, factories, the automotive industry, etc.)
  5. Close to the American border providing trading opportunities, more jobs, and shopping, etc.

Q

How were the Appalachian mountains formed?

A
  • Formed 300 million years ago
  • Eurasion plate collided with North Anerican Plate forming the mountain ranges
  • Mountains are now eroded from weather conditions and old age

Q

Provide examples of how Canada’s natural features change over time.

A
  1. Appalachian mountains: Slowly being eroded down over time, therefore, appearing in a less jagged, snow capped way that the Western Cordillera does.
  2. Animals: Have been hunted, trapped, fished and killed therefore in risk of becoming endangered or even extinct.
17
Q
