Rock Types
This rock forms when magma or lava cools.
What is Igneous
A boundary where two plates move toward each other and collide.
What is convergent boundary.
The thinnest layer of Earth made of oceanic and continental crust.
What is the crust
The process where dense oceanic crust sinks beneath continental crust.
What is subduction
The German scientist who proposed continental drift.
Rock formed from compacted & cemented sediment.
What is Sedimentary
A boundary where two plates move away from each other.
The largest layer of Earth.
Mantle
A valley formed when tectonic plates separate.
Rift Valley
The scientist who proposed seafloor spreading.
Harry Hess
Rock formed by heat and pressure.
What is Metamorphic
A boundary where plates slide past each other horizontally (San Andreas Fault).
Transform boundary
The rigid outer layer made of the crust and upper mantle.
Lithosphere
The formation of new ocean crust as magma rises and plates move apart.
Seafloor Spreading
The supercontinent that existed about 225 million years ago.
What is Pangaea
Process by which rocks change over time.
What is the Rock Cycle
This type of boundary is most associated with earthquakes.
Transform plate boundaries
The soft layer of the mantle that tectonic plates move on.
Asthenosphere
What happens when oceanic and continental crust converge?
The oceanic crust subducts beneath continental crust, forming volcanoes
This boundary type forms mid-ocean ridges and rift valleys.
Divergent boundary
Law stating matter is recycled, not destroyed.
What is the Law of Conservation of Mass/Matter.
This type of boundary forms mountains, deep ocean trenches, and volcanoes.
Convergent plate boundaries
Earth’s layers in correct order from outermost to innermost.
What are crust, mantle, outer core, inner core?
These are what drive plate movement inside Earth.
Convection currents in the mantle
Earth's outer layer is made of....
hard, solid rock
