9. molten rock on land
11. a super continent formed
12. the innermost layer of the Earth
13. German meteorologist and geophysicist
18. a seafloor mountain system formed by plate tectonics
19. the breaking down or dissolving of rocks and minerals on the surface of Earth

1. he sudden release of strain energy in the Earth's crust, resulting in waves of shaking that radiate outwards from the earthquake source

8. a mixture of molten and semi-molten rock found beneath the surface of the Earth
9. features on the Earth's surface that make up the terrain
10. he sudden release of strain energy in the Earth's crust, resulting in waves of shaking that radiate outwards from the earthquake source
14. the geological process in which earthen materials are worn away and transported by natural forces such as wind or water
15. a large continuous mass of land conventionally regarded as a collective region
16. the continental landmasses were “drifting” across the Earth, sometimes plowing through oceans and into each other
