Plate Tectonics

The movement of the tectonic plates is caused by

• the rotation of the Earth.

• convection currents in the Asthenosphere

• the gravity of the iron-nickel core.

• the Moho discontinuity.

There are three types of plate boundaries. Which choice is NOT a type of plate boundary?

• convergent
• thrust
• divergent
• transform

The map in the picture shows tectonic plate boundaries. This map would be useful in predicting the location of future

• droughts

• hurricanes

• earthquakes

• tornadoes

What geological forces might be responsible for this range of mountains?

• diverging tectonic plates
• erosion of the land by the ocean
• converging tectonic plates
• deposition of sediments by the ocean
  

The Earth’s surface is not a solid surface but is divided into

• several oceanic plates.
• continental and crustal plates.
  
• seven continental plates.
• continental and oceanic plates.
  

Where are earthquakes MOST LIKELY to occur?

• close to the equator

• close to the center of tectonic plates

• at divergent or convergent plate boundaries

• at transform plate boundaries

The Atlantic Ocean gets about 3-5 ______ wider each year.

• centimeters
• kilometers
• miles
• meters

Where would sea floor spreading most likely occur?

• At convergent boundaries (oceanic vs. oceanic)

• At convergent boundaries (oceanic vs. continental)

• At divergent plate boundaries (oceanic vs. oceanic)

• At transform plate boundaries

A plate boundary where two plates move away from each other is called

• Divergent Boundary
• Convergent Boundary
• Transform Boundary
• Subduction

A Plate Boundary where two plates move toward each other is called

• Convergent Boundary
• Divergent Boundary
• Transform Boundary
• Subduction
