What is the relationship between volcanic activity and earthquakes based on the information provided?

They follow a predictable pattern of alternating occurrences

They have no correlation

They occur in completely different locations

They often occur in similar areas (correct)

How does the text describe the current relationship between Africa and Europe with respect to their past positions?

Africa is now farther from Europe than it used to be

The distance between Africa and Europe has remained constant over time

Africa is now closer to Europe than it used to be (correct)

Which statement accurately represents the scenario of plates studied by Dr. Bailey and his team?

Soft, solid rock rose from underneath the plates and hardened at the edges of both plates
