Geographical Effects

latitude effect on the climate The farther north it is in North America the colder it is.

elevation effect on the temperature in the united states The farther north it is in North America the colder it is.

Geology

Rock Types

[11] [12]

Sedimentary [13] [14]

Alaska

All of central USA

Western Canada

Northern islands of Canada

Florida

All of Texas and surrounding areas

Cuba

Northeast Mexico

Yucatan peninsula

They are there because there was water for the clasts to cement in or their was the correct material in a certain area.

Volcanic (Igneous) [15]

Western Mexico

Southern Central America

Northern California

Washington

Oregon

Scattered around Alaska

A tiny bit in northern Canada

A sliver near the Carolinas

A bit in Cuba

In the past, there was volcanic activity causing lava to cool quickly on the surface of the Earth. It is extrusive.

Plutonic (Igneous) [16]

West coast of Alaska and British Colombia

Scattered around North to Northeastern Canada

Southern California to Baja California

East coast/New England

They form when magma rises into the upper crust and cools. The magma cools slowly and doesn’t reach the surface. They magma can come from an old volcano or can just flow from deep in the Earth.

Metamorphic [17]

Rocky Mountains

Northern/Northeastern Canada

Islands on top of Canada

Appalachian Mountain area

A tiny bit in central Alaska

Scattered in Central America

The metamorphic rocks form in their locations because the location has the correct heat or pressure amount to change the rock. Also, there is the correct parent rock in the location.

Minerals

Mining Resources

[18]

In the southern part of Alaska there are two places coal is mined.

Coal is also mined in the Southwestern part of Canada and the South/Middle part of Canada.

Coal is mined in the middle of the United States.

There are a total of 11 places coal is mined in bulk in North America.

Gold is mined in different parts of North America: The Northeastern part of Alaska and in Canada just above the Great Lakes.

Lead and Zinc are mined in the center of Canada.

Iron is mined in the eastern most part of Canada, in the center of Mexico, and in northeast United States.

Oil is mined in the upper/middle part of Alaska. Oil is also mined in the southwest corner of Canada. In addition, oil is mined in southeast United States and in east and west Texas.

Copper is mined on the western coast of North America and in the center of Canada.

Bauxite is mined in Cuba.

Uranium is mined in the middle of Canada.

Silver is mined in the center of Mexico, in Washington, and in southeast Canada.
