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

all_540.gif [1],

Sedimentary [12] [13]

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) [14]

Western Mexico

Southern Central America volcanic.html.jpeg

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) [15]

West coast of Alaska and British Colombia

Scattered around North to Northeastern Canada

Southern California to Baja California plutonic.html.jpeg

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 [16]

Rocky Mountains

Northern/Northeastern Canada metamorph.html.jpeg

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

[17]

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. world-mineral-map.htm.jpeg

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.

Plate Tectonics

North America is made up from the North America Plate, the Cocos Plate, the Juan de Fuca Plate, and the Caribbean plate.

North America Plate boundary type- Convergent and Transform

Juan de Fuca Plate boundary type- Divergent and Convergent

Cocos Plate boundary type- Convergent

Caribbean Plate boundary type- Transform

North America Plate margin type- Destructive and Conservation

Juan de Fuca Plate margin type- Destructive and Conservation

Cocos Plate margin type- Destructive and Constructive

Caribbean Plate margin type- Destructive and Constructive [18] [19]

Volcanoes

North America has volcanic activity.

Locations of Volcanoes

West Coast

Cascade Mountains

Aleutian Islands

Central Mexico

Pacific Coast of Central America (Heavily populated with volcanoes)

Yellowstone

A few in the Rocky Mountains

Scattered in Arizona and New Mexico

Hawaii

There are no volcanoes in the east.

[20]


Types of Volcanoes

There are a lot of cinder cones on the West Coast of North America.

In the Cascade Mountains and the surrounding areas, there are a lot of composite volcanoes.

In Hawaii, Northern California, and Oregon there are a few shield volcanoes. The largest is Mauna Loa in Hawaii.

There are lava domes scattered along the west coast.

[21]


Recent Eruptions

Mt. St. Helens – Washington current

Popocatepetl – Mexico 2007

Arenal - Coasta Rica current

Colima - Mexico current

Conception - Nicaragua 2010

Fuego – Guatemala current

Kilahuea - Hawaii current

Akutan - Alaska 1996

Earthquakes

North America commonly has earthquakes.

Locations of Recent Earthquakes [23] N_America.gif

All of these earthquakes have occurred within the past week. Also, the larger the square, the larger the magnitude of the earthquake.

Rocks and Their Relation to Plate Tectonics

The rocks of North America are related to plate tectonics because of the tectonic rock cycle. rkcyarc3.gif
