the part of the Earth's crust that forms land masses.

Convection currents in the lower mantle and outer core are caused mainly by ....

the inner core's extremely high temperatures.

The mantle is made of

very hot rock that flows like hot asphalt.

Why do hotter molecules rise and cooler molecules sink?

Hotter molecules are less dense.

The BEST model to show Earth's layers is with a

peach half, showing the skin, flesh, and pit.

It is most likely that the high pressure in the inner core comes from

the weight of the layers above the inner core.

Which one is NOT an example of destructive forces?

volcanic eruption making an island

From the information about Earth's layers we have studied...

the deeper the layer, the hotter the temperature.

Which BEST describes Earth's inner core?

solid iron and nickel that's very hot

Which would be a BENEFIT of having a molten outer core with convection currents?

It creates a magnetic field around Earth that protects us.
