Across
- 2. the layer of rock that forms Earth’s surface (crust)
- 5. made of the crust and the top of the mantle. Divided into plates
- 7. over 200 million years ago when all of the continents were connected
Down
- 1. plates move 2.5-15 cm/year in many different directions
- 3. the lower part of the mantle that is solid but acts like a fluid because it flows, made of magma
- 4. heat from here moves up through the rock and through the mantle so the mantle flows with convection currents
- 6. molten rock
