Earth Layers

Earth layersAnswers
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
Grinding can cause ground waves which lead to earthquakes
