Plate Tectonics

2. - the outermost shell of a terrestrial planet.
3. - molten rock that issues from a volcano or from a fissure in the surface of a planet (such as earth) or moon.
7. - one in which one side of the plate, the hanging wall, moves up and over the other side, the foot wall.
8. - one on which the displacement of the far block is to the left when viewed from either side.
10. - is the mostly solid bulk of Earth's interior.
14. - having fault plane dips <45o, usually <30o.
15. - a set of stress directed toward the center of a rock mass.

1. - the block above the fault has moved downward relative to the block below.
4. - planet we live on and studied by geologists.
5. - massive slab of solid rock made up of Earth's lithosphere (crust and upper mantle).
6. - the force applied to a rock and may cause deformation.
9. - the sudden release of strain energy in the Earth's crust.
11. - cracks in the crust where there is no movement.
12. - a fracture or zone of fractures between two blocks of rock.
13. - a geologic structure that is formed by layers or beds of rock being bent.
14. - stress which stretches rocks in two opposite directions.
