Plate tectonics sample questions

Rocky or rigid outer part of Earth consisting of the brittle crust and the top part of the upper mantle

• Lithosphere

• Oceanic Crust

• Continental Crust

• Asthenosphere

Mantle convection is the very slow creeping motion of Earth’s solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface.

• Lithosphere

• Earthquake

• Convection Currents

• Core

Solid, outer layer and is made of both the oceanic and continental crust.

• Hydrosphere

• Core

• Mantle

• Crust

Hot fluid or semi-fluid material below or within the earth's crust from which lava and other igneous rock is formed on cooling.

• Convection Current

• Lithosphere

• Core

• Magma

The thick part of the earth's crust that forms the large landmasses. It is generally older and more complex than the oceanic crust.

• Oceanic Crust

• Continental Crust

• Magma

• Inner Core

In the region where two continental plates collide, what geological feature MOST often forms?

• an ocean

• a volcano

• a river valley

• a mountain chain

Crustal plates that pull apart from one another MOST likely form

• volcanic island arcs

• strike-slip faults

• oceanic trenches

• rift zones

Which two plates collided with each other to form the Himalayan Mountains?

• Nazca and Eurasia

• Indo-Australian and Eurasian

• North America and Antarctic

• South American and Indo-Australian

Which of these tectonic plate boundaries is most likely to form a volcano.

• a continental plate colliding with a continental plate

• an oceanic plate sliding past a continental plate

• a continental plate sliding past a continental plate

• an oceanic plate colliding into a continental plate

What causes the tectonic plates to continually to move?

• Convection currents

• Volcanic and seismic activity

• Strong winds and storms

• Rotation of the solid core
