Plate Boundaries
Name the boundary where two move toward each other
Convergent
Which type of rocks form when magma, or melted rock from inside the Earth, cools and hardens.
Igneous Rocks
Name the layer of the Earth that we live in and that is very thin in comparison to the other 3 layers.
Crust
True or false:
Pangaea was a giant supercontinent where all the continents were once joined together.
True
What is the main cause of an earthquake?
Tectonic plate movement
Name the boundary where two plates move away/pull apart from each other
Divergent
Which type of rocks are formed by the accumulation, compaction, and cementation of sediments in layers over time.
Sedimentary Rocks
Name the layer of the Earth that is made of hot, dense, liquid rock and is the thickest layer of the Earth.
Mantle
True or false.
Continents move very quickly over time.
False
Describe how a volcano is formed
When magma (molten rock) from deep within the Earth's mantle rises to the surface
Name the plate boundary where two plates slide past each other
Transform
Which types of rocks are transformed from pre-existing igneous, sedimentary, or other metamorphic rocks through high heat, intense pressure, and chemically active fluids deep within the Earth's crust.
Metamorphic Rocks
Name the layer of the Earth that is made of iron and nickel.
Outer Core
The geological theory that Earth's continents were once joined together in a single supercontinent called Pangaea before breaking apart and drifting to their current positions over millions of years.
Continental Drift
The place earthquakes are most common
Tectonic plate boundaries
The geological process where one tectonic plate slides beneath another and sinks into the Earth's mantle, typically when plates collide and one is denser, like an oceanic plate going under a continental one.
Subduction
Name 3 different ways sedimentary rocks are formed
Weathering
Erosion
Deposition
Compaction
Cementation
Inner Core
The scientist who proposed the idea of Continental Drift.

San Andres Fault
Name one type of metamorphic rock and explain what it is commonly used for
