Earth's Layers
Which layer of Earth is also known as the lithosphere?
The Crust
Where plates come together.
Convergent boundary
Give one type of ocean formation caused by tectonic plates?
Volcano, Trench, Mid-ocean ridge (mountains)
The supercontinent that existed about 200 million years ago.
Pangea
Formed when plates diverge on land.
Rift valley
Which layer of Earth do we live on?
The Crust/Lithosphere
Where plates move apart
Seafloor spreading occurs at this type of plate boundary:
Convergent Boundary
Where does the heat come from that drives convection currents?
Earth's core
Where most volcanos, earthquakes, and tsunamis occure
The Ring of Fire
Which layer is responible for the movement of tectonic plates?
The Mantle
Where plates slide past eachother.
Transform Boundary
These formed the Hawaiian islands.
Underwater Volcanoes
Give one piece of evidence supporting Pangea's existence:
Formed when plates converge on land, buckle, and fold.
Mountains
The thinnest layer of Earth
The lithosphere (crust)
The boundary where subduction can occur.
Convergent Boundary
What formation is created when subduction occurs in the ocean?
Trenches
The process by which new crust is created under the ocean
seafloor spreading
When one plate slides beneath another.
Subduction
Which layer of Earth produces its magnetic field?
The Outer Core
Crust is neither created nor destroyed at this type of boundary.
Transform boundary
What formation is created during seafloor spreading?
Mid-ocean ridge
The scientist that theorized Pangea's existence and found evidence to prove it. (only last name required)
Alfred Wegener
Occurs when a transform boundary suddenly shifts
Earthquake
