Which of the following is commonly expected near a "textbook" subduction zone (that is, near a subduction zonethat is so perfect
and free of confusing complications that you would use it in a textbook to teach students)? (A) Pull-apart earthquakes and faults.
(B) Basaltic mid-ocean-ridge-type volcanoes.
(C) Piled-up mud and other things scraped off the descending slab.
(D) Slide-past (or transform, with horizontal but not vertical movement) earthquakes and faults.
(E) Basaltic hot-spot-type volcanoes.
The given question is related to the subduction zone which forms in a convergent type of plate boundary.
In a convergent plate boundary, when two plates collide, it results in the formation of a subduction zone, where the denser plate sinks below the lighter one. As the heavier plate descends, a significant amount of materials (sediments) are scraped off, and eventually deposited at the edge of the over-riding plate, which is commonly known as the accretionary prism. In addition to this, when the down-going plate reaches the layer of the asthenosphere, the rocks melt and mix with the magma. The magma slowly again rises upwards towards the surface in the over-riding plate, giving rise to the formation of volcanoes which are basaltic in nature. For example, Mount Fuji is a basaltic strato-volcano.
Thus, the correct answers are options (C) and (E).
A fault scrap is a small offset of the ground surface moves vertically with the respect to the other and the faulting is attributes to the displacement of the land with the movement along the faults and is indicated by the consequent erosion along the geologic faults. They are hard and weak rocks and the scrap formation is equal to the vertical weight displaced.
1. It can be triggered by tectonic plate movement. - <u>both</u>
2. The name means "harbor wave." - <u>tsunamis</u>
3. It’s movement of land triggered by gravity. - <u> mass wasting</u>
4. Creep and topple are names for two types of this hazard. - <u>mass wasting</u>
5. Scientists use deep ocean assessment and reporting (DART) to warn of this hazard. - <u>tsunamis</u>
6. One example is mud flowing down a hill and onto a highway.
<u>mass wasting</u>
Explanation:
The characteristics of the tsunamis are related to those associated with the shaking of the ground that is produced by the movement of the tectonic plates from below as in the event of the earthquakes and thus the sudden release of the violent energy create huge killer waves and they can also lead to the mass wasting phenomenon.
<u>Hence the process of mass wasting occurs due to the movement of the layers of them is under the flow of the gravity and is a hazard that is associated with the earthquakes.</u>
In this examples, we can see that the places with the highest altitude (meters above sea level) are also the places with the lowest atmospheric pressure. Therefore, we can conclude that the opposite is true too. The places with the lowest altitude are the ones with the highest atmospheric pressure. The place with the lowest altitude is New Orleans, as it is located 2 m below sea level.
Major reduction in cropland has been noted due to afforestation and urbanization. The growing of grasslands and forests as well as building of cities have slowed down the conversions of spaces into croplands.
The EU is working on the decline slowly but us determined to succeed in establishing croplands.
