1.
1 Layer: Lithosphere
2.
2 Layer: Mantal
3.
3 Layer: Asthenosphere
4.
4 Layer: Core
5.
Alfred Wegener: A German scientist who proposed the theroy of continental drift
6.
Asthenosphere: Less ridiged than the lithosphere the rock is soild
7.
Cause of Plate Movement: when plates move because of convection currents and the mantle
8.
Continental Crust: the older, thicker, and less dense part of Earth's crust; the bulk of Earth's land masses made of granite
9.
Convergent Boundary: A tectonic plate boundary where two plates collide, come together, or crash into each other.
10.
fault: break in the rock
11.
fold: fold squeezed into a bend in the rock
12.
geologist: scientist that studies earth crust
13.
Inner Core: Solid metal
14.
Oceanic Crust: The portion of earth's crust that primarily contains basalt, is relatively dense
15.
Outer: Malten metal iron, nickel
16.
Plastic: Hard but can still bend and move.
17.
Plate Tectonics: the theory that proposes that earth's outer shell consists of individual plates that interact in various ways and thereby produce earthquakes, volcanoes, mountains, and the crust itself
18.
Subduction Zone: the region where an oceanic plate sinks down into the asthenosphere at a convergent boundary, usually between continental and oceanic plates
