Across
- 2. denoting or relating to rock that has undergone transformation by heat, pressure, or other natural agencies, e.g. in the folding of strata or the nearby intrusion of igneous rocks.
- 3. relating to or involving volcanic processes.
- 5. and oceanic lithosphere.
- 6. (of rock) that has formed from sediment deposited by water or air.
- 7. naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles.
- 8. the sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate.
- 9. a fault along a plate boundary where the motion is predominantly horizontal. It ends abruptly where it connects to another plate boundary, either another transform, a spreading ridge, or a subduction zone
- 10. hypothesis that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed.
Down
- 1. is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent boundaries within continents initially
- 4. A tectonic plate is a massive, irregularly shaped slab of solid rock, generally composed of both
- 5. when plates move towards each other and collide. When a continental plate meets an oceanic plate, the thinner, denser, and more flexible oceanic plate sinks beneath the thicker, more rigid continental plate.
