Seismic Waves Review

Earthquakes happen every day. Most are too small for humans to notice.

• True
• False

The shaking and trembling that results from the Earth's plates movement

• Mountains
• Earthquakes
• Volcanoes
• Fault-block mountains

When plates break or slip past each other they form these

• mountains
• tectonic plates
• Fault lines
• earthquakes

Earthquakes release these which let us study what the Earth is made out of

• Tectonic Plates
• Seismic Waves
• Plateaus
• P Waves

These are the first waves released during an earthquake

• S waves
• Surface Waves
• P waves

These are the secondary, or second waves to be released. They cannot travel through the liquid outer core

• S waves
• Surface Waves
• P waves

This is the area beneath the Earth's surface where the earthquake begins

• epicenter
• focus
• fault line
• tectonic plate

This is the area above ground where the earthquake starts

• focus
• epicenter
• p waves
• plate boundary

We use this tool to measure seismic waves during earthquakes

• Seismographs
• magnitude
• actual magnitude
• sonograph

This is the name of the single digit number that means how powerful an earthquake is. It is measured on the Richter scale

• Force
• Stress
• Magnitude
• Plate Boundary
