2. The process that occurs when one tectonic plate moves under another tectonic plate
6. drift Wegener’s theory that all continents were once connected in a single large landmass that broke apart about 200 million years ago and drifted slowly to their current positions
8. The mechanical and chemical processes that change Earth’s surface over time
10. The moving of weather material, or sediment, from one location to another
14. A process in which the weight from the layers of sediment forces out fluids and decreases the space between sediment grains
15. A naturally occurring solid composed of minerals, rock fragments, and sometimes other materials such as organic matter
16. boundary- The boundary between two plates that move toward each other
18. boundary The boundary between two plates that move away from each other
19. The process through which sediment turns into rock

1. rock Igneous rock that forms as magma cools underground
3. The laying down or settling of eroded material
4. A naturally occurring, inorganic solid that has a crystal structure and a definite chemical composition
5. tectonics Theory that Earth’s surface is broken into large, rigid pieces that move with respect to each other
7. A process in which minerals dissolve in water crystallize between sediment grains.
9. spreading The process by which new oceanic crust forms along a mid-ocean ridge and older oceanic crust moves away from the ridge
11. surface
12. boundaries- The boundary between two plates that slide past each other
13. cycle The series of processes that change one type of rock into another type of rock.
17. rock Igneous rock that forms when volcanic material erupts, cools, and crystallizes on
