Geological Oceanography

What is the thickest layer of the Earth?

• the crust
• the mantle
• the outer core
• the inner core

What is the core made of?

• steel
• iron 
• aluminum
• iron and nickel

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

Identify the layer of the earth labeled # 6

• crust

• mantle

• outer core

• inner core

What happens to pressure as we move from the crust to the inner core?

• Pressure Decreases
• Pressure Increases
• Nothing

Which layer is made of "flowing" solid rock (think clay or pudding)?

• crust

• mantle

• outer core

• inner core

Which layer is made (mostly) of LIQUID iron and nickel?

• crust

• mantle

• outer core

• inner core

As you travel from the inner core to the crust, how would temperature, pressure and density of the material change?

• The would all increase
• The would all decrease.
• Nothing, the layers are made of the same material throughout
• Temperature would decrease, but pressure and density would increase

Scientists determine what Earth’s interior looks like by using:

• Volcanoes
• Seismic Waves
• Continental Drift
• Convection Currents

Which crust is thicker

• oceanic

• continental

• they are have the same density so it doesn't matter

• science isn't able to tell yet
