Across
- 2. the sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate.
- 5. is a linear feature that exists between two tectonic plates that are moving away from each other.
- 10. a line on a map joining points of equal height above or below sea level.
- 11. are formed by the movement of large crustal blocks when forces in the Earth's crust pull it apart.
- 12. form mainly by the effects of folding on layers within the upper part of the Earth's crust.
Down
- 1. rigid outer part of the earth, consisting of the crust and upper mantle.
- 3. is an actively deforming region where two (or more) tectonic plates or fragments of the lithosphere move toward one another and collide.
- 4. is a type of map characterized by large-scale detail and quantitative representation of relief
- 6. height above a given level, especially sea level.
- 7. is the uppermost layer of the oceanic portion of a tectonic plate.
- 8. is an underwater mountain range, formed by plate tectonics.
- 9. is a type of fault whose relative motion is predominantly horizontal, in either a sinistral or dextral direction
