Earth's Layers and Plate Tectonics

What are the three layers that make up the Earth?

• Crust, Mantle, Core

• Yellow Flesh, Stone, Hard Skin

• Oceans, Mountains, Continents

• Lithosphere, Magma, Outer Core

Which layer of the Earth is the thinnest?

• Crust

• Mantle

• Outer Core

• Inner Core

What is the semi-liquid layer beneath the Earth's crust called?

• Mantle

• Core

• Lithosphere

• Magma

What are the two divisions of the Earth's core?

• Molten Core and Solid Core

• Upper Core and Lower Core

• Iron Core and Nickel Core

• Outer Core and Inner Core

Why does the inner core of the Earth stay solid despite its high temperature?

• The inner core is made of a different material

• Gravity prevents the metals from melting

• The temperature is not as high as the surface of the sun

• The inner core is not actually hot

What is the process called when tectonic plates move and interact with each other?

• Convection Currents

• Plate Tectonics

Which plate margin involves two plates sliding against each other?

• Destructive or Convergent Plate Margin

• None of the above

• Constructive or Divergent Plate Margin

• Conservative or Transform Plate Margin

What are the most devastating tectonic hazards caused by plate movements?

• Heatwaves, Hailstorms, Blizzards

• Droughts, Landslides, Avalanches

• Hurricanes, Tornadoes, Floods

• Volcano Eruptions, Earthquakes, Tsunamis
