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 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 their 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 on 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.
