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
Sedimentary [[11]]
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
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
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
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.
