Crust

The solid outer layer of the earth is called the?

Pangaea

Before there became seven continents there was one supercontinent known as?

Continental Drift

The movement of the continents is called?

Mantle

A liquid and semi liquid layer that exists between the outer core and crust?

Subduction Zone

An area of the earth's crust where one plate slides beneath another is called?

4.5 billion years

The earth is believed to be about how many years old?

Maritime Tropical

Which type of air mass comes over warm water and makes the air warm and moist?

Gradient

Refers to the slope of the land?

Relief

The difference in elevation between points of land?

Convection Current

The current in a fluid, such as magma, that circulates as the fluid is heated and cooled?

Weathering

The wearing down forces of the atmosphere?

Continental Arctic

Which type of air mass comes over cold land and makes the air cold and dry?

Climate

__________________is how we describe the pattern of weather conditions of the long term.

Western Cordillera

Made up of a series of parallel mountain ranges---the Coast Mountains, the Columbia Mountains, and the Rocky Mountains.

Canadian Shield

Canada's landform region that has the oldest rock.

Innuitian Mountains

In the Far North having rugged peaks that rise over 2000m with steep-sided valleys.

Appalachian Mountains

These mountains were formed about 375 million years ago. Found in Atlantic Canada.

Great Lakes - St. Lawrence Lowlands

Found to the south of the Canadian Shield. As sea receded left a flat area of very fertile soil.

Hudson Bay Lowlands

A low area of the shield with a build up of Paleozoic rock to a depth of 2000m. Located in northern Ontario and Manitoba

Interior Plains

Located between the Canadian Shield and the Western Cordillera, it is an extensive area of plain that was created when inland seas receded.

Arctic Lowlands

Area to the south of the Innuitian Mountains.

Mostly tundra.

Inner Core

Which is solid...the inner core or outer core?

Plate Tectonics

The theory that the earth's crust moves which produces mountains, trenches, earthquakes, and volcanoes.

Geology

Types of rocks and the history of them?

Erosion

The moving of weathered material?

Deposition

Where eroded materials are dropped create new landforms?

Precipitation

Rain, snow, sleet, or hail that falls to the ground?

Temperature

The amount of heat energy in the air?

Decrease

Generally as latitude increases temperatures tend to ?

Altitude

Height of an object in relation to the ground.

Months

On a Climate graph, what is on the x-axis?

Line

On a Climate graph, a ___________________ graph drawn in red to represent temperature

1. The fit of continental land masses

2. The presence of similar fossils in rocks now separated by oceans

3. Matching magnetic bands in the rocks on either side of the mid Atlantic Ridge

4. Fossils of sea animals have been found high in the rocks of the Himalayas

Which evidence is there of the theory of continental drift?

Ocean Currents

Latitude

Clouds and Precipitation

Air Masses and Wind

What 4 factors that affect Global Climate?

Humidity

The amount of moisture in the air is called?
