Across
- 8. the part of the earth between the core and the the crust
- 9. Trench a long narrow steep-sided depression in the earth's oceanic crust, usually lying above a subduction zone
- 10. Ridge a long, seismically active submarine ridge system situated in the middle of an ocean basin and marking the site of the upwelling of magma associated with seafloor spreading
- 12. Geological and environmental conditions that include long-term and short-term geological processes
- 13. Similar to Landslide but with snow and ice instead
- 14. A fracture in a volume of rock, most earthquakes occur on active faults
- 17. a fault in which rock strata are displaced mainly in a horizontal direction, parallel to the line of the fault.
- 19. The type of boundary where the plates are coming apart
- 21. the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
- 24. The breaking down of rocks and minerals into the ground
- 26. Breaking the rock into smaller pieces but not changing the rock's composition
- 27. a stiff, sticky fine-grained earth, typically yellow, red, or bluish-gray in color and often forming an impermeable layer in the soil
- 28. Waves a longitudinal earthquake wave that travels through the interior of the earth
- 29. A violently abrupt shaking of the ground that can cause mass destruction
- 31. Indonesian term that descrbes hot/cold mixture of water that flows down volcanoes
- 32. fine sand, clay, or other material carried by running water and deposited as a sediment, especially in a channel or harbor
- 34. A foliation parallel to the bedding which is commonly found in limbs of tight and isoclinal folds, where the axial plane is parallel or sub-parallel to the limbs.
- 35. Push a proposed mechanism for plate motion in plate tectonics
- 36. The outer part of the earth's interior, including the crust and upper mantle
- 37. when a certain area is submerged underwater
- 41. The term for when masses of earth and/or rock slide down a mountain or cliff
- 42. The theory about the earth´s crust and how the plates move slowly over the mantle
Down
- 1. Boundary a type of fault whose relative motion is predominantly horizontal
- 2. The transformation of rock into one or more new compounds
- 3. hot fluid or semifluid material below or within the earth's crust from which lava and other igneous rock is formed by cooling.
- 4. a hypothetical supercontinent that included all current land masses, believed to have been in existence before the continents broke apart during the Triassic and Jurassic Periods
- 5. hot molten or semifluid rock erupted from a volcano or fissure, or solid rock resulting from cooling of this.
- 6. The point at which rays or waves meet after reflection or refraction, or the point from which diverging rays or waves appear to proceed.
- 7. occur where two blocks of rock are forced together by compression.
- 11. The set of processes where rocks continually change into other types of rock
- 15. A type of boundary where two plates move towards each other and collide
- 16. Also known as the fall line
- 18. Exactly above the focus of an earthquake on the surface of earth
- 20. A type of hill/mountain that has a crater at the summit where lava might erupt from
- 22. map on a certain location
- 23. The action off dropping of leaving something
- 25. Waves a transverse earthquake wave that travels through the interior of the earth and is usually the second conspicuous wave to reach a seismograph
- 30. Wegener the man who was the first one to think that plate tectonics existed
- 33. The upper layer of the earth
- 38. a long high sea wave caused by an earthquake, submarine landslide, or other disturbance
- 39. a cavity in the ground, especially in limestone bedrock, caused by water erosion and providing a route for surface water to disappear underground
- 40. a loose granular substance, typically pale yellowish brown, resulting from the erosion of siliceous and other rocks and forming a major constituent of beaches, riverbeds, the seabed, and deserts
