Plate Tectonics and Hazards

Most geologists think that the movement of Earth's tectonic plates is caused by

• the rotation of the Earth.

• the Earth's magnetic field.

• subduction.

• convection currents.

A location where two tectonic plates collide is known as a _________ boundary.

• Convergent
• Divergent
• Transform
• Spreading

Which layer of Earth flows slowly and causes the crust to move?

• Crust

• Mantle

• Inner Core

• Outer core

What is the correct order (starting from the surface) of Earth’s layers?

• crust, outer core, inner core, mantle

• mantle, outer core, inner core, crust

• crust, mantle, outer core, inner core

• outer core, inner core, crust, mantle

What is an earthquake?

• When the earth causes an upward thrust in the epicenter.
• When the earth moves up and down along the ocean floor.
• When tectonic plates slide against each other causing the earth to move. 

• None of the above

Subduction means.....

• one plate goes under another plate

• two plates slide past each other

• two plate collide and form folded mountains

Sea-floor spreading explains how.....

• new crust is created at a divergent boundary

• volcanoes are formed on continents

• deep sea trenches are formed

An opening on the Earth's crust through which hot molten rock flows out from deep inside the Earth.

• Volcano

• Fault line

• Fold

• Crater

Which of the following causes Earth's tectonic plates to move?

• Energy from the Sun
• Magnetic Pole Reversal
• Convection currents in the mantle
• Faults in Mountain Ranges

What type of event will occur at this boundary?

• Earthquake
• Volcano Eruption
• Tornado
• Mountain Building
