Inside Our Earth

If we compare our earth to the lava lamp, we can see how the movement of heat in the center of our earth is like the wax in the lava lamp. This movement of heat is:

• conduction

• convection

• radiation

• solar

The layer of Earth made of solid rock (mostly basalt & granite) and is the thinnest?

• Crust

• Mantle

• Core

• Lithocore

Which layer of Earth is solid and why?

• The inner core is solid because of movement of the outer core.

• The inner core is solid because of the freezing temperatures.

• The inner core is solid because of the extreme pressure from the other layers.

• The outer core is solid because of the extreme pressure from the other layers.

Which of Earth's layers is made of SOLID iron and nickel?

• crust 

• mantle

• outer core

• inner core

Which layer is made partly of crust and partly of mantle material?

• lithosphere

• atmosphere

• mesosphere

• athensosphere

How do scientists know the earth has layers?

• Grandpa told them.

• Seismic wave data and direct evidence from rock samples.

• From drilling into the earth.

• Samples from the lava and magma of volcanos.

The Earth's magnetic field is caused by

• magnets placed at the north and south poles by elves.

• convection currents in the atmosphere.

• the lithosphere floating on the asthenosphere.

• convection currents in the liquid outer core.

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

Which layer of Earth is LIQUID iron and nickel?

• upper mantle

• lower mantle

• outer core

• inner core
