• axial valley and ocean trench

• mid-ocean ridge and volcanic Island

• volcanic island and axial valley

How can you describe the process of subduction?

• When an oceanic plate slide past each other

• When an oceanic plate, one that has become denser due to cooling descends below another plate

• When the earth’s brittle surface is pulled apart

• None of these

Which of the following BEST describes the lithosphere?

• a rigid zone above the asthenosphere

• the name given to the molten outer core

• a source of magma at divergent boundaries

• none of these

The reason why tectonic plates on earth moves.

• Convection on the mantle

• Earthquakes

• Volcanoes erupting

• Mountain forming

The Alpine fault cuts through New Zealand. At these location, two plates are sliding past each other slowly over time. What plate boundary must exist at Alpine fault?

• Convergent boundary

• Divergent boundary

• Transform Boundary

• None of these

Why do plates get subducted?

• They are very dense.

• They are very thin.

• They are very light.

• They are very thick.

According to Alfred Wegener’s hypothesis of continental drift the earth is _____________.

• Go to the nearest stairway and run down

• Seek immediate protection beneath a heavy, sturdy piece of furniture

• Use elevator and go to an open space

What evidence can you point to in favor of the theories of plate tectonics and continental drift? Which among the following is NOT true?

• Plate Tectonics Theory includes the movement of the continents

• Alfred Wegener explained the presence of similar mountain ranges across continents

• The presence of coal deposits near the poles

• The study of the Earth's magnetic field, provides support for the idea of magma generation along mid-ocean ridges
