• At convergent boundaries, hot spots and transform boundaries

• At divergent boundaries, convergent boundaries, and transform boundaries

Many scientists rejected continental drift theory when it was first proposed because

• studies of the ocean floor revealed its younger age

• Wegner had collected little evidence to support his theory

• reversals in Earth's magnetic field had not yet occurred

• Wegener could not explain how Earth's continents moved

A continental-continental collision causes

• oceanic-continental subduction to occur

• oceanic-oceanic subduction to occur

• hot spots to form

• mountain ranges to form

Subduction occurs

• when an oceanic plate and another plate converge

• when two continental plates converge

• when two oceanic plates pull apart

• along a transform boundary in the ocean

Plates move horizontally past each other along which boundary?

• continental boundary

• Transform boundary

• convergent boundary

• divergent boundary

One of the forces that cause tectonic plates to move is convection currents in the asthenosphere.

• true

• false

What would be most effective in minimizing the potential damage caused by an earthquake?

• Installing sirens in areas prone to earthquakes

• Building structures that withstand ground vibrations

• Increasing the amount of concrete during road building

• Requiring the recycling of metal and wood products

Mid-ocean ridges form long chains of “_______” that rise up from the ocean floor.

• rivers

• valleys

• mountains

• rocks

Seafloor spreading is a geologic process in which type of plates split apart from each other.

• convergent

• divergent

• transform

• dinner

Bedrock that is closer to oceanic ridges is younger in age than bedrock that is farther away. What can be best concluded from this information?

• The shape of Earth’s lithosphere is continually changing.

• The movement of continental plates is caused by volcanic eruptions.

• The oceans are becoming deeper and warmer as more rocks are produced.

• The rocks on the ocean floor are producing tectonic plates that are converging.
