Plate Tectonics

Which is the correct order for the layers of the Earth?

• Inner mantle, outer mantle, core, outer core

• Crust, core, mantle, outer core

• Crust, mantle, outer core, inner core

Which is the thinnest layer of the Earth?

• Crust

• Mantle

• Core

What is slab pull?

• When newer, less dense crust sinks

• When older, more dense crust sinks

• When older, less dense crust sinks

Where are earthquakes created?

• At destructive plate boundaries

• At conservative plate boundaries

• At all plate boundaries

Which is lighter: oceanic or continental crust?

• Oceanic

• Continental

• Neither. They are both the same

How does a collision boundary differ from a destructive plate boundary?

• A collision boundary forms through two continental plates, whereas destructive boundaries form from one continental and one oceanic

• A collision boundary has plates moving towards one another, whereas destructive boundaries have plates moving away from one another

• Collision boundary are only found in less developed countries

What happens at a constructive plate boundary?

• Two plates move apart and new land is created

• One plate is forced beneath another

• Plates slide side by side

Where could we see an example of a constructive plate boundary?

• The San-Andreas fault in California

• The Himalayas

• The Mid-Atlantic Ridge

What is another name for a conservative plate boundary?

• Transformative plate margin

• Subduction zone

• Divergent plate margin

What happens at a conservative plate boundary?

• Plates move in opposite directions

• Plates move in the same direction, but at different speeds

• Plates move either in opposite directions or in the same direction, but at different speeds
