5. A supercontinent that existed on earths hundred of millions of years ago

16. An event where 2 or more objects come into violent contact or crash with each other
17. Opening in the Earth's crust where magma erupts from beneath the surface forming a mountain shape.
18. A string of volcanoes or earthquakes around the Pacific Ocean

21. A zone of fractures in the Earth's crust where tectonic plates have moved

1. A geological process where one tectonic plate slides and sinks beneath each other
2. Something like a rock that has been changed by exposure to heat, pressure and more.
4. The geological process where new oceanic crust is formed at mid ocean ridges as tectonic plates pull apart.
6. Process by which heat is transferred by movement of a heated fluid such as air or water.
7. The scientific theory that the Earth's outer shell is broken into large plates
