IG 7 Earth's Interior

What is the correct order (starting from the surface) of Earth's layers?

• crust, inner core, mantle, outer core

• crust, mantle, outer core, inner core

• inner core, outer core, mantle, crust

• mantle, outer core, inner core, crust

What are the two types of crust?

• top crust, bottom crust

• maritime Polar, continental Tropical

• oceanic crust, continental crust

• deep dish, thin

Which crust is thicker?

• Oceanic

• Divergent

• Continental

• Convergent

Oceanic crust is _____ than continental crust

• denser

• less dense

The thick region between Earth's core and crust. Convection currents move heated rocks to the surface, while colder, denser rocks sink. This causes the tectonic plates to move.

• crust

• mantle

• outer core

• inner core

Identify the BEST explanation for the important role of the liquid outer core, and not the solid mantle, in the forming of Earth's magnetic field.

• The mantle moves very slowly compared to the outer core.

• The outer core moves more quickly than the mantle and has a higher metal content (iron and nickel).

• The outer core is mostly iron and nickel and the mantle is mostly silicon and oxygen.

• The outer core is closer to the center of the planet than the mantle.
