Science Vocab

1. naturally occurring solid composed of minerals, rock fragments, and sometimes other materials such as organic matter.
4. laying down or seducing of eroded material.
7. Rock-Igneous rock that forms as magma cools underground.
9. process in which minerals dissolved in water crystallize between sediment grains.
11. Tectonics-Theory that Earth’s surface is broken into large, ridged pieces that move with respect for each other.
12. moving of one material or sediment from one location to another.
14. Rock-Ignerious rock that forms when volcanic material erupts, cools, and crystalizes on Earth’s surface.
15. cycle-The series of process that change one type of rock into another type of rock.
16. naturally occurring, inorganic solid that has a crystal structure and a definite chemical composition.
18. process that occurs when one tectonic plate moves under the another tectonic plate.

2. process in which the weight from the layers of sediment forces out fluids and decreases the space between the sediment grains.
3. process through which sediment turns into rock.
5. Drift-Wegener’s hypothesis 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.
6. Boundary-The boundary between two plates that move away from each other.
8. Boundary-The boundary between two plates that move toward each other.
10. Boundaries-The boundary between two plates that slide past each other.
13. mechanical and chemical process that change Earth;s surface over time.
17. Spreading-the process by which new oceanic crust forms along a mid-ocean ridge and older oceanic crust moves away from the ridge.
