Across
- 2. a line on a diagram or map connecting points relating to the same time or equal times.
- 4. the equilibrium that exists between parts of the earth's crust
- 7. the sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate.
- 10. a flat plate with multiple "wells" used as small test tubes
- 12. a geological feature where two or more lithospheric plates move towards each other and collide
- 13. a linear shaped lowland between several highlands or mountain ranges produced by the action of a geologic rift
- 15. a process in which a section of the earth's crust is folded and deformed by lateral compression to form a mountain range.
- 16. a large volcanic crater, especially one formed by a major eruption leading to the collapse of the mouth of the volcano.
Down
- 1. formed by the movement of large crustal blocks along faults formed when tensional forces pull apart the crust
- 3. a cone formed around a volcanic vent by fragments of lava thrown out during eruptions.
- 5. the continental landmasses were “drifting” across the Earth, sometimes plowing through oceans and into each other
- 6. large volcanic eruptions that cover extensive areas of land or ocean floor with basalt lava flows
- 8. a body of intrusive igneous rock.
- 9. the pulling force exerted by a cold, dense oceanic plate plunging into the mantle due to its own weight
- 11. a type of plate tectonic boundary where two tectonic plates slide horizontally past each other.
- 14. a geological phenomenon where the Earth's magnetic north and south poles switch positions
