Plate tectonics

What evidence is there for plate tectonics?

• Topographic maps that show elevation

• Evidence from drilling into the Earth.

• Satellite images that show the outlines of the plates.

• The geologic events that occur at plate boundaries such as earthquakes andvolcanic eruptions.

What happens in a subduction zone?

• Two plates slide past each other and cause earthquakes.

• Two plates come together of different densities and one sinks under the otherand melts.

• Two oceanic plates diverge and create a ridge.

• Two continental plates collide and form mountains.

What is the creation of new crust at divergent oceanic boundaries called?

• Seafloor spreading

• Subduction zones

• Volcanic island arcs

• Faulting

What are the three main types of plate boundaries that exist?

• Confine, define, and translate

• Convergent, divergent, and transform

• Contingent, defendant, and transcribe

• Complete, deplete, and transplant
