Earth Science, Earthquakes, Pre Assessment

Many earthquakes happen along the borders of...

• Countries
• Tectonic Plates
• Climate Zones
• None of the above.

The Richter scale measures:

• the amount of radon gas released
• the movement of plates
• the strength of an earthquake
• the weight of tectonic plates

The first wave of an earthquake is . . . . 

• tsunami
• surface wave
• p wave
• s wave

The epicenter of an earthquake shows up where?

• Below the surface of the earth.
• On the surface of the earth.
• Next to the P Wave.
• At the end of a Surface Wave

Which ocean in the world is also known as the "Ring of Fire"

• Atlantic
• Indian
• Arctic
• Pacific

Which of these seismic waves creates the most damage during an earthquake?

• primary
• secondary
• surface

Liquefaction is when...

• the soil behaves like liquid
• the ground becomes liquid
• magma rises to the surface
• buildings are damaged, crumbling like liquid

What is the epicenter of an earthquake

• the location along a fault where the first motion of an earthquake occurs
• a seismic wave tht travels along the surface of Earth
• the point on Earth's surface directly above the earthquake's focus
• the last place that motion in an earthquake is detected

An instrument that detects and measures earthquakes is a 

• seismogram
• focus seismic map
• focus
• seismograph 

How much bigger is a magnitude 8 earthquake compared to magnitude 7 one on the Richter Scale?

• 1 time bigger
• 10 times bigger
• 100 times bigger
• 1000 times bigger
