Effects of Plate Tectonics & Plate Boundaries

All plate boundaries...

• Form from stress

• Form faults

• Cause earthquakes

• Form new landforms

• All of these

A force that deforms rocks

• faults

• stress

Fractures/breaks where there has been a displacement of material on both sides

• faults

• stress

What is the relationship between earthquakes and tectonic plates?

• major earthquakes cause tectonic plates to move

• major earthquakes are centered along tectonic boundaries

• major earthquakes are centered within the middle of tectonic plates

• there is no relationship

Convergent plate boundaries

• plates move away from each other

• plates move toward each other

• plates slide against each other

Divergent plate boundaries

• plates move away from each other

• plates move towards each other

• plates slide against each other

• one plate moves over top of another

Transform plate boundaries

• plates move away from each other

• plates move towards each other

• plates slide against each other

• one plate moves over top of another

The formation of the Hawaiian Islands is associated with

• Divergent boundaries

• Convergent boundaries

• Transform boundaries

• Hot spots

Based on the process of ocean floor formation (sea floor spreading), which of the following is true?

• The ocean floor is oldest closest to the continents and youngest at oceanic ridges

• The ocean floor is youngest closest to the continents and oldest at oceanic ridges

• All the same age because it was formed during planetary accretion

• Oldest at the deepest levels and youngest in the more shallow areas

Seafloor spreading at oceanic ridges is _________ because...

• destructive because new crust is formed

• destructive because old crust is destroyed

• constructive because old crust is destroyed

• constructive because new crust is formed
