Across
  1. 3. Hypothesis that a single large landmass broke up into smaller landmasses to form the continents, which then drifted to their present locations
  2. 5. Solid, outer layer of Earth that consists of the crust and the rigid upper part of the mantle
  3. 9. Images that are taken from space by satellites that orbit the Earth
  4. 11. Process in which material is laid down
  5. 12. When rocks suddenly break along faults; often occur at plate boundaries
  6. 15. Boundary between tectonic plates that are colliding
  7. 16. The size and shape of the land surface features of a region, including its relief
  8. 17. Natural process by which atmospheric and environmental agents, such as wind, rain, and temperature changes, disintegrate, and decompose rocks
  9. 19. These types of maps show rock types and ages, including geologic features
  10. 21. Weathering that is the chemical breakdown and decomposition of rocks by natural processes in the environment
  11. 22. The collision of two continental plates can form these tall geologic features
Down
  1. 1. Process by which one lithospheric plate moves beneath another plate as a result of tectonic forces
  2. 2. Forms when rocks break; break where tension at divergent boundaries is greater than the strength of a rock
  3. 3. Any movement of matter that results from differences in density; may be vertical, circular, or cyclical
  4. 4. Made when Earth’s lithosphere pulls apart to form long, narrow, faulted valleys
  5. 6. There are three types of these, including convergent, divergent, and transform
  6. 7. Process by which wind, water, ice, or gravity transports soil and sediment from one location to another
  7. 8. Block of lithosphere that consists of the crust and the rigid, outermost part of the mantle
  8. 10. Process by which new oceanic lithosphere forms when magma rises to Earth’s surface at mid-ocean ridges and solidifies, as older, existing seafloor moves away from the ridge
  9. 13. Boundary between tectonic plates that are moving away from each other
  10. 14. Map that shows the surface features of Earth
  11. 18. Boundary between tectonic plates that are sliding past each other horizontally
  12. 20. Weathering that is the mechanical breakdown of rocks into smaller pieces that is caused by natural processes and that does not change the chemical composition of the rock material
  13. 22. Occurs on the ocean floor; magma rises through cracks in the oceanic lithosphere, forming volcanic mountains
