EARTHQUAKES &
VOLCANOES
EFFECTS OF PLATE TECTONICS
When plates move, they bump into each other
Depending on the type of plate boundary, different deformations result
Two special events/formations happen as well:
Earthquakes Volcanoes
EARTHQUAKES
Earthquake: shaking of the ground that results from the movement of rock beneath Earth's surface
Stress on rocks from pushing/pulling changes its shape/volume of the rock
Types of Stress:
Shearing ? causes rocks to slip Tension ? stretches rock Compression ? pushes rocks together
FAULTS
Fault: a break in Earth's crust where slabs of crust slip past each other.
Rocks on both sides of a fault can move up or down or sideways
Usually occur along plate boundaries, where the forces of plate motion compress, pull or shear the crust so much that it breaks.
TYPES OF FAULTS
Strike-Slip Faults: where rocks on either side of the fault slip past each other sideways with little up or down motion
Occurs at transform plate boundaries Ex: San Andreas Fault, California
Normal Faults: a fault at an angle so one block of rock lies above the fault and the other block of rock lies below the fault, caused by tension
Occurs where plates diverge Hanging wall ? half that lies above Footwall ? half that lies below
