The Earth is made up of distinct layers which have different characteristics. How would a geologist best distinguish between the lithosphere and crust?

The lithosphere is liquid while the crust is solid

The lithosphere is the layer of the crust closest to the mantle.

The crust is along the surface of the Earth, while the lithosphere is near the core.

The crust, along with the upper mantle, make up the lithosphere.

Which of the following characteristics could be used to correctly indicate a relationship between two of Earth's layers?

The inner and outer cores are both composed of solid iron.

The crust and mantle are the densest layers.

The core radiates heat, which has a role in the convection of the mantle.

The lithosphere has convection due to heating and cooling, while the core radiates heat.

What causes the mantle to "flow"?

The mantle flows because of convection currents that are caused by very hot material in the mantle rising, cooling, and then sinking.

The mantle flows because of wind waves that are caused by very cold wind in the mantle .

The mantle flows because of sound waves that are cause by very loud sound in the mantle.

The mantle flows because of light waves that are caused by very bright lights in the mantle.
