Across 2. stress that occurs when forces act to squeeze an object 5. the theory that explains how large peices of the Earth's outermost layer, called tectonic plates, move and change shape (2 words) 6. the soft layer of the mantle on which the tectonic plates move 11. a block of lithosphere that consists of the crust and the rigid outermost part of the mantle (2 words) 12. a break in a body of rock along which one block slides relative to another 13. the process by which new oceanic lithosphere forms as magma rises toward the surface and solidifies (3 words) 14. stress that occurs when forces act to stretch an object 15. the rising of reigons of the Earth's crust to higher elevations 16. the strong lower part of the mantle between the asthenosphere and the outer core 18. the boundary formed by the collision of two lithospheric plates (2 words) 19. the thin and outermost layer of the Earth above the mantle

Down 1. the hypothesis that states that the continents once formed a single landmass, broke up, and drifted to their present locations (2 words) 3. the solid, outer layer of the Earth that consists of the crust and the rigid upper part of the mantle 4. the sinking of reigons of the Earth's crust to lower elevations 7. the boundary between tectonic plates that are sliding past each other horizontally (2 words) 8. the bending of rock layers due to stress 9. the boundary between two lithospheric plates that are moving away from each other (2 words) 10. the layer of rock between the Earth's crust and core 17. the central part of the Earth above the mantle
