Crossword Puzzle for Plate Tectonics

1. volcanoes erupt from this substance called "Lava'. Once the magma is ready to be set free it causes the volcano to erupt.
3. Boundary, A convergent boundary is an area on Earth where two or more plates collide.
7. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust
9. Subduction as the process by which tectonic plates sink into Earth's mantle.
12. “Crust” describes the hard surface shell coving the mantle of our planet.
14. Tectonics, a theory explaining the structure of the earth's crust.
15. As the magma flows out, it cools, hardening to form new crust, This fills in the gap created by the Tectonic plates.
16. Boundary, A divergent boundary occurs when two tectonic plates move away from each other
17. The researchers believe this shift is the earliest proof that modern like plate motion happened between two to four billion years ago.
18. inside the crust and core it is pitch solid.
19. A tectonic plate can be a massive, irregularly shaped solid rock.

1. Earth has many different layers such as, the mantle, Core, and crust.
2. When two plates come in contact with each other through plate tectonics, scientists can use the density of the plates to predict what will happen.
3. Earth's core is the very hot and dense center of our planet.
4. The lower boundary of a plate depends on the temperature of the mantle material.
5. Once a tectonic plate Alters is shifts something in or out of the earth.
6. The continents are made within the plates.
8. a process that takes place at convergent boundaries of tectonic plates.
10. Boundary, Transform boundaries are places where plates slide sideways past each other.
11. in earth, Earth's shell cracked into these plates.
13. Earthquakes occur along lines, cracks in Earth's crust where tectonic plates meet.
18. floor, Bathymetry, the shape of the ocean floor, is largely a result of a process called plate tectonics.
