Layers of the Earth

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

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

What is the best way scientists know about the structure of the earth?

• Volcano

• Oceanic

• Seismic Waves

• Lithosphere

Which layer of the earth is the hottest?

• crust

• mantle

• outer core

• inner core

Fill in the blank: __________________ also happens inside the earth (see image). Tremendous heat and pressure within the mantle cause hot magma to flow in convection currents (rising and falling of liquid magma). This causes the plates in the crust (lithosphere) to shift and move and sometimes break.

• convection

• radiation

• conduction

• wind

Which of the following is true regarding the composition of the lithosphere?

• The lithosphere is mostly liquid, with some medium-density materials, such as silicon.

• The lithosphere is more plastic and flows slowly compared to the solid crust of Earth.

• The lithosphere includes the core and the lower portion of the mantle.

• The lithosphere includes the crust and the uppermost portion of the mantle, which is sold and rigid.
