Unit 1 Test Review

What are the 2 main seismic body waves?

• P & S waves
• L & R waves
• P & L waves
• S & R waves

Primary waves are:

• Faster, motion and force travels in a straight line
• Faster, motion and forces are perpendicular to each other, wave goes up and down.
• Slower, motion and forces are perpendicular to each other, wave goes up and down.
• Slower, motion and force travels in a straight line

Secondary waves are:

• Faster, motion and force travels in a straight line
• Faster, motion and forces are perpendicular to each other, wave goes up and down.
• Slower, motion and forces are perpendicular to each other, wave goes up and down.
• Slower, motion and force travels in a straight line

True/False: P-waves travel through liquids and solids, while S-waves only travel through solids.

• True
• False

Rayleigh and Love waves are types of:

• Body waves
• Surface waves
• Water waves
• Tsunami

The layers of the Earth, in order from surface to the center of the Earth are:

• Inner core, Outer core, Crust, Mantle
• Inner core, Outer core, Mantle, Crust
• Crust, Mantle, Outer core, Inner core
• Crust, Outer core, Mantle, Inner core

The crust is mostly

• Solid
• Liquid
• Plastic like semi-solid

The mantle is mostly

• Solid
• Liquid
• Plastic like semi-solid

The Inner Core is

• Solid
• Liquid
• Plastic like semi-solid

The Outer Core is

• Solid
• Liquid
• Plastic like semi-solid
