Weathering |
The break down of rock by physical and chemical processes. |
|
Erosion |
The process by which sediment (broken down rock) is moved from one place to another. |
|
Deposition |
The process by sediment that is moving is dropped off and comes rest. |
|
Igneous Rock |
Formed from lava or magma that has cooled. |
|
Sedimentary Rock |
Formed when broken down rock gets compressed and cemented together. |
|
Metamorphic Rock |
Forms from extreme temperature, pressure, or chemical processes that cause the existing rock to change. |
|
Rock Cycle |
The process in which rock changes forms from one type to another. |
|
The layers of the Earth by chemical composition |
Crust Mantle Core |
|
The layer of the Earth where convection occurs |
Mantle |
|
The layers of the Earth by physical properties. |
Lithosphere Asthenosphere Mesosphere Outer Core Inner Core
|
|
The liquid layer of the Earth. |
The outer core |
|
Pangea |
A large super continent made up of all of the continents grouped together that existed ~245 million years ago. |
|
Sea-floor spreading |
When molten rock fills the space between two diverging oceanic plates and forms new land. |
|
Plate tectonics |
The large scale movement of the Earth's lithosphere. |
|
Continental Crust |
The less dense, "fluffier" form of crust that sits above the level of the oceans. Where the dry land is. |
|
Oceanic Crust |
The more dense, thinner form of crust that is covered with water. |
|
Convergent boundary |
When two tectonic plates are moving towards each other. |
|
Divergent Boundary |
When two tectonic plates are moving away from each other. |
|
Transform Boundary |
When two tectonic plates are sliding past each other horizontally. |
|
The ring of fire |
A name given to an large area of explosive volcanoes that form on the convergent plate boundaries of the Pacific Ocean. |
|
Hot Spot |
Responsible for volcanic islands appearing in the middle of oceanic plates. Formed from where the mantle pushes magma through the crust (called a mantle plume) to vent the tremendous pressure from inside the Earth. |
