- 3. A transform fault or transform boundary, sometimes called a strike-slip boundary, is 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
- 5. A geomagnetic reversal is a change in a planet's magnetic field such that the positions of magnetic north and magnetic south are interchanged.
- 6. the sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate.
- 8. all the continents that were once part of a super continent
- 10. A convergent boundary is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone
- 12. the gradual movement of the continents across the earth's surface through geological time.
- 13. the rigid outer part of the earth, consisting of the crust and upper mantle.
- 15. Reverse Polarity is when a receptacle is wired backward. This happens when the “hot” wire, also known as the black or red wire, is wired on the neutral side and the neutral wire is wired on the “hot” side. Looking at the featured image above, the outlet tester shows exactly this.
- 16. A natural remanent magnetization closely parallel to the present ambient geomagnetic field direction. (b) A configuration of the Earth's magnetic field with the magnetic negative pole, where field lines enter the Earth, located near the geographic south pole.
Down
- 1. 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.
- 2. 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. Divergent boundaries within continents initially produce rifts, which eventually become rift valleys.
- 4. Ridge push or sliding plate force is a proposed driving force for plate motion in plate tectonics that occurs at mid-ocean ridges as the result of the rigid lithosphere sliding down the hot, raised asthenosphere below mid-ocean ridges
- 7. he 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.
- 9. a theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates which move slowly over the underlying mantle.
- 11. 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.
- 14. Slab pull is that part of the motion of a tectonic plate caused by its subduction. In 1975 Forsyth and Uyeda used the inverse theory method to show that
