4. - to move toward one point and join together
5. – a break in the Earth’s surface along which rock has moved
6. - separate from another route, especially a main one, and go in a different direction.
9. - places where plates slide sideways past each other. At transform boundaries lithosphere is neither created nor destroyed.
11. – a map that shows the elevation of natural and artificial features of a region
12. - takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced or sinks due to gravity into the mantle.
13. – the region where one tectonic plate slides under another tectonic plate
15. – a photograph taken from a satellite

1. - A tectonic boundary where two plates are moving away from each other and new crust is forming from magma that rises to the Earth's surface between the two plates.
2. – a process by which weathered rock is picked up and moved to new places
3. - Earth's outer layer, the crust, is divided into a set of large moving plates. The lines where they meet
7. - A tectonic boundary where two plates are moving toward each other
8. – a large chain of volcanic mountains on the ocean floor
10. – the difference in elevation between two contour lines
14. - height above a given level, especially sea level
