  1. 3. 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.
  2. 4. referring to DC and causing electrons to flow from the base metal to the electrode
  3. 5. violent shaking of the earth
  4. 7. the gradual movement of the continents across the earth's surface through geological time
  5. 8. was a supercontinent that existed during the late Paleozoic and early Mesozoic eras, forming approximately 300 million years ago. It began to break apart around 100 million years after it formed
  6. 9. the rigid outer part of the earth, consisting of the crust and upper mantle
  7. 11. Plate tectonics is a scientific theory that describes the large-scale motion of Earth's lithosphere
  8. 13. In plate tectonics, a divergent boundary or divergent plate boundary is a linear feature that exists between two tectonic plates that are moving away from each other within continents initially produce rifts which produce rift valleys
  9. 15. the sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate.
  10. 16. Slab pull is the movement of tectonic plate lithosphere due to convection currents in the asthenosphere. When the currents circulate they pull the tectonic plates down causing subduction. The slab pull force is a tectonic plate force due to subduction
Down
  1. 1. A geomagnetic reversal is a change in the Earth's magnetic field such that the positions of magnetic north and magnetic south are interchanged
  2. 2. A transform fault or transform boundary, also known as conservative plate boundary since these faults neither create nor destroy lithosphere, is a type of fault whose relative motion is predominantly horizontal in either sinistral or dextral direction
  3. 3. In plate tectonics, a convergent boundary, also known as a destructive plate boundary, is an actively deforming region where two tectonic plates or fragments of lithosphere move toward one another and collide
  4. 6. the formation of new areas of oceanic crust, which occurs through the upwelling of magma at midocean ridges and its subsequent outward movement on either side
  5. 10. a mountain or hill, typically conical, having a crater or vent through which lava, rock fragments, hot vapor, and gas are being or have been erupted from the earth's crust.
  6. 12. 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. An example is the Mid-Atlantic Ridge
  7. 14. Ridge push or sliding plate force is a proposed mechanism for plate motion in plate tectonics. Because mid-ocean ridges lie at a higher elevation than the rest of the ocean floor, gravity causes the ridge to push on the lithosphere that lies farther from the ridge
