Earth's Tectonics Plates, Volcanoes, & Earthquakes Test (modified)

What is the name of the supercontinent that scientists say existed millions of years ago where all the continents were joined together?

• Pangea
• North America
• Americana
• Euroasia

Based on THIS MAP, what evidence supports the continental drift hypothesis?

• The continents appear to fit well together
• Several continents have similar mountain ranges
• Similar plants are found on several continents
• Similar fossils are found on several continents

Why do some states like California have more earthquakes than other states, like Pennsylvania?

• California is located on a hot spot
• California is located near the Pacific Ocean
• California is located near a plate boundary
• Pennsylvania is located near a Great Lake which prevents earthquakes

Looking at this map of tectonic plates, how is the South American Plate moving compared to those around it?

• The South American plate is converging with both (moving toward) the African plate and Nazca plate
• The South American plate is diverging from (moving away) the African plate and converging with (moving toward) the Nazca plate
• The South American plate is diverging (moving away) from both the African Plate and Nazca Plate
• The South American Plate is converging with (moving toward) the African Plate and converging (moving away) from the Nazca Plate

When the Mount Etna volcano erupted in 1169, 15,000 people were killed. Mount Etna continues to erupt often but fewer people are killed. Why?

• People have learned how to build houses to protect them from lava
• Mount Etna's eruptions have been less powerful
• People have learned how to observe and track precursor events before an eruption takes place

What is a "precursor event"

• Smaller earth activities (ie. earthquakes) that happen BEFORE a more major event (ie. volcano erupting)
• Smaller earth activities (ie. earthquakes) that happen AFTER a more major event (ie. Tsunami)

How do plates move at a CONVERGING boundary?

• The plates move AWAY from each other
• The plates SLIDE BY each other
• The plates move TOWARD each other

How do plates move at a DIVERGING boundary?

• The plates move AWAY from each other
• The plates SLIDE BY each other
• The plates move TOWARD each other

How do plates move at a TRANSFORM boundary?

• The plates move AWAY from each other
• The plates SLIDE BY each other
• The plates move TOWARD each other

The San Andreas Fault in California is located at which type of boundary?

• Converging
• Diverging
• Transform
