Unit 5

4. / the makeup of a rock; describes either the minerals or elements present in it
5. / a mountain that forms when molten rock, called magma, is forced to the Earth’s surface
7. / the boundary between two tectonic plates that are moving away from each other
10. / the theory that continents can drift apart from one another and have done so in the past
11. / the region where an oceanic plate sinks down into the asthenosphere at a convergent boundary, usually between continental and oceanic plates
13. / the central, spherical part of the Earth below the mantle
16. / a shaking or trembling of a portion of the earth
18. / a break in the Earth’s crust along which blocks of the crust slide relative to one another due to tectonic forces

1. / the boundary between two tectonic pates that are sliding past each other horizontally
2. / the boundary between two colliding tectonic plates
3. / the theory that the Earth’s lithosphere is divided into tectonic plates that move around on top of the asthenosphere and mantle
4. / the transfer of thermal energy by the circulation or movement of a liquid or a gas
6. / the amount of matter in a given space; mass per unit volume
8. / the thin, outermost layer of the Earth, or the uppermost part of the lithosphere.
9. / the outermost, rigid layer of the Earth that consists of the crust and the rigid upper part of the mantle
12. / an act, process, or result of lifting up a part of the Earth’s surface
14. / the layer of the Earth between the crust and the core
15. / the hot liquid that forms when rock partially or completely melts; may include mineral crystals
17. / magma that flows onto the Earth’s surface
