Ch. 9 Earthquakes Lesson 1

What are earthquakes?

• vibrations in sound waves

• vibrations in the ground that result from movement along breaks in Earth's lithosphere

• vibrations in the atmosphere that can affect the geosphere

• divergent plates

• tectonic plates

• convergent

• divergent

• reverse

Shallow earthquakes are common along ____________ plate boundaries where plates separate.

• convergent

• divergent

• detergent

What is a fault

• is a break in Earth's lithosphere where one block of rock moves toward, away from or past another block.

• when someone has a bad disposition/habit

• when a rock moves in any direction along the litosphere

What are the 3 main kinds of faults?

• strike slips; reverse and seismic

• strike-slip; average and normal

• strike slip; reverse and normal

What are seismic waves?

• when the ocean hits the shores with such intensity it causes rock deformation

• the center of an earthquake

• when rocks move in any direction along a fault, and release energy in the Earth's crust

Seismic Waves begin...

• along the fault were rocks first begin to move

• with a volcano

• with a tsunami
