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
