Tectonic Flashcards
what are the 2 types of crust?
contiental and oceanic
tell me about contiental
made of Granite
its thick but less dense then oceanic
tell me about oceanic crust
made of Basaltic Rocks
its thinner then contiental but more dense
what are the 4 plate boundaries?
destructive plate
constructive plate
conservative plate
collision plate
tell me about destructive plate
a convergent plate boundary where two plates (oceanic plate and the continental plate) meet, and the more dense oceanic plate is forced under the continental plate.
oceanic and oceanic
Subduction Zones, Volcanic Arcs, Earthquakes
tell me about constructive plate
the tectonic plates are moving away from one another. oceanic and continental
Earthquakes
tell me about conservative plate
plate boundaries where two plate are either slipping past each other in opposite directions or at different rates in the same direction. oceanic or continental.
Volcanic Activity, Earthquakes
tell me about collision plate
A collision plate boundary occurs when two continental plates converge and collide. The collision leads to significant geological effects, primarily the formation of mountain ranges.
continental and continental
Mountain Building, Earthquakes
