Rock Cycle & Plate Tectonics

2. Wegener, This scientist believed all continents were once a large landmass.
3. These are directly responsible for the texture of rocks and can be rounded or jagged.
7. The downward movement of one of Earth's plates beneath another one.
9. An area where two or more tectonic plates move on a collision course.
10. Currents, The movement of fluid cause by differences in temperature.
11. This is determined by the size shape and pattern of its grains.
13. A natural mixture of sand gravel and crushed stone.
14. An area where two plates slide past each other in opposite directions.

1. Rock, After millions of years of heat and pressure it will change existing rock into a different type of stone.
4. Tuzo Wilson, This scientist observed cracks in the continents similar to the ones that had already been discovered on the ocean floor.
5. Rock, The process of compaction and cementation form these sand particles into stone.
6. An area where two or more tectonic plates move away from one another.
8. Composition, This is what determines the color of all rock types.
12. Rock, The most common and fastest forming rock type on Earth.
15. Cycle, This process shows the basic relationships among igneous, sedimentary, and metamorphic rocks.
