Dynamic Planet

The Earth's rigid upper layer is called the lithosphere. This solid part of our planet has two parts. Select them from the list below.

• crust

• upper mantle

• lower mantle

• outer core

The dynamic nature of our planet, including earthquakes and volcanic eruptions, can be explained by:

• continental drift

• plate tectonics

• seafloor spreading

• subduction zones

How does volcanic ash in Earth’s atmosphere affect solar radiation?

• It increases the amount of solar radiation that reaches Earth’s surface.

• It increases the amount of solar radiation that is absorbed by oceans and lakes.

• It increases the amount of solar radiation that is reflected into space.

• all of the above

Where does the heat come from that drives this convection current in the mantle? 

• the Sun

• the crust

• the mantle

• the core

As you travel from the crust down to the inner core, how would temperature, pressure and density of the material change?

• all three would increase

• all three would decrease

• all three would stay the same

• The temperature would decrease, but pressure and density would increase.
