plate Tectonics

Wegener proposed this hypothesis

Each of the rigid slabs of Earth's lithosphere is called a

The mechanism responsible for producing new sea floor

The type of plate boundary where plates move together

Ancient magnetism in rock structures

This theory states that Earth's crust consists of 7 smaller sections

When rocks exhibit the same magnetism present in the magnetic field

The type of plate boundary where plates move apart

A rising plume of magma such as the one that created the Hawaiian islands

The supercontinent that broke into smaller continents

A region where an oceanic plate descends into the athsenosphere

A down faulted valley
Created along spreading centers on continents

Occurs where plates grind past each other

The temperature where magnetic minerals lose their magnetism

Rocks that exhibit magnetism that is opposite to the present magnetic field

A chain of small volcanic islands that form when two oceanic plates converge

A deep feature that forms along a subduction zone

An elevated portion of the sea floor that forms along divergent plate boundaries
