Plate Tectonics
Ththis particular study stack is about plate tectonics and earth's interior
| Term | Definition |
|---|---|
| Converging Plates | When Tectonic Plates Collide With Each Other |
| Alfred Wegener | A German Scientist That Came Up With The Theory Of Continental Drift |
| Diverging Plates | When Tectonic Plates Drift Apart From Each Other |
| Crust | Thin Layer That Covers Earth, There Are 2 Types, Oceanic and Continental. Oceanic Crust Is More Dense And Thinner (5-70 km) |
| Mantle | Hot Rock Beneath The Crust (2867 km) |
| Lithosphere | In Greek, Lithos Means "Stone" And It Is Te Most Upper Part Of The Mante |
| Athenosphere | Below The Lithosphere, In Greek, Athenos Means "Weak". This Layer Is Like Soft Tar, But still Hard As Rock. |
| Outer Core | This Liquid Forms The Outer Part Of The Core Despite All The Pressure (2266 km) |
| Inner Core | Dense Ball Of Iron And Nickel, The Pressure Is What Makes It So Solid And So Dense (1216 km) |
| Continental Drift | The Theory That The Plates Were Once One SuperContinent Pangaea, And Have Since Drifted Apart. |
| Tectonic Plates | Earth Is Divided Up Into Tectonic Plates That Move Because Of Heat Conduction In The Mantle |
| Conduction | Heat Transfer Within A Solid Or Solids That Are Touching |
| Convection | Heat Transfer Within A Fluid. During Convection, Heat Particles Flow |
| Radiation | The Transfer Of Heat Energy Through Space |
| Subduction Zone | When a Converging Plate Occurs, But One Plate Is More Dense Than The Other And Moves Under The Other Plate, Back Into The Mantle, Ready To Be Recycled As Hot Rock. |
| Seismic Waves | The Waves Of Energy Created By An Earthquake |
| Mid-Ocean Ridge | A Fault Line In The Middle Of The Ocean And Is Pulled Apart By Divergent Plates So Sea-Floor Spreading Occurs |
| Sea-Floor Spreading | When There Are 2 Divergent Plates Which Pull Each other Away, There Would Be Abyss All The Way Until The Mantle, But Sea-Floor Spreading Causes That The Magma In The Mantle Flows Up And Conceals The Hole |
| Transform Boundary | When 2 Plates Slip Past Each Other |
