Rock Types
Rocks formed by the compaction of sediment buildup.
What is sedimentary rocks?
Layer of the earth shown at location A.
What is the crust?
Plates that collide with one another.
What are convergent plate boundaries?
Define continental drift.
What is the theory that all continents were once joined together but broke up and began drifting apart?
The name of the supercontinent described in the theory of continental drift.
What is Pangea?
Layer of the Earth encompassing the upper mantle and crust. Also shown as location B.
What is the lithosphere?
Plates that move apart from one another.
What are divergent plates?
Subduction occur along these plate boundaries.
What are convergent plate boundaries?
The movement that churns molten rock material and moves tectonic plates.
What is convection currents?
Rocks that are formed form extremely high temperatures and pressures.
What is metamorphic rock?
Portion of the mantle that is still solid but can flow. Also seen in location C.
What is the asthenosphere?
Plates that slide past one another.
What are transform fault boundaries?
Continental-continental convergent plates boundaries form these landforms.
What are mountains?
The scientist that proposed the theory of continental drift.
Who is Alfred Wegner?
Rocks formed by cooling magma or lava.
What are igneous rocks?
The hottest and most pressurized layer of the Earth. Also seen in location E.
What is the inner core?
The layer of the Earth that makes up tectonic plates.
What is the lithosphere?
Along this boundary ocean trenches are formed.
What are oceanic-oceanic convergent boundaries?
The three types of convergent plate boundaries.
What are oceanic-oceanic, continental-oceanic, and continental-continental.
Igneous rock that are formed on the surface of the Earth.
What are extrusive igneous rocks?
The liquid layer of the earth. Also seen as location D.
What is the outer core?
The denser of the two types of crust.
What is oceanic crust?
Mid-ocean ridges are responsible for this.
What is the production of more crust as the divergent plates separate?
Two of the four pieces of evidence that support the theory of continental drift.
What are similar plant and animal fossils among continents, matching rock types and mountain chains, similar climate shown in glacial evidence, coastlines match like puzzle pieces?
