Earth layers | Answers |
Outermost Layer | Crust |
Crust | Ocean and Continents Lay Atop |
First Layer | Mantle |
Mantle Composed | Dense Rock |
Crust + Upper Most layer of the Mantle | = Litosphere |
Under Lithosphere | Asthenosphere |
Asthenosphere | Elastic |
Convection Currents | Travel Thru the Asthenosphere |
Convection Currents (create Movement) | Which shifts the Tectonic Plates |
3 Categories of Plate Boundaries | Convergent, Divergent and Transform |
Convergent Boundaries | Converge or move together (Collide) |
Convergent Boundaries | Subduction as they submerse or drive down one of the plates - Sinking of Land Eathquake, sinking of crust to expose magma volcanic |
Convergent Boundaries | Create the Ring of Fire and are of great seismic and volcanic activity |
Convergent NOT creating subduction | Mountains Appear - Plates thrust Upward |
Divergent Boundaries | Diverto or Move the plates away from one Another |
Divergent Boundaries | Are typically with Ocean Plates |
Deep Valleys | Ocean Floor aka 'rifts |
Divergent Plates DO NOT | Typically cause Volcanic activity but not great seismic activity |
transform Plate Boundaries | Plates Sliding by one another |
Site of Great ? | Friction as the plates slide grinding past one another |
Grinding causes stress | leads to landslides |
San Andreas Fault | is a transform plate boundary |
