Tectonic Plates

The Ring of Fire is an area where a large number of earthquakes and volcanic eruptions occur. What claim can be made about the Ring of Fire from this information?

• It is the only place on Earth where earthquakes can happen.

• The edges of the tectonic plates are moving in this area.

• It represents the areas where tectonic plates are the thickest.

• It has been getting larger since Earth first formed.

• Oceana

• Pangea

• North America

When magma pushes to the surface and spreads 2 oceanic plates apart what could form?

• rocky mountain

• Earthquake

• mid-Atlantic ridge

• volcano

Describe the most likely relationship between these mountains and nearby tectonic plates.

• Transform Boundary

• Subduction Boundary

• Convergent Boundary

• Divergent Boundary

The earthquakes experienced in California are related to tectonic plates because these catastrophic events are the result of -

• two tectonic plates sliding past each other.

• tectonic plates melting as they slide into the mantle.

• tectonic plates being weathered over time.

• two tectonic plates pulling away from each other.
