2. Which of the following correctly describes seafloor spreading? A. New oceanic crust is formed in the middle of tectonic plate
s and then spreads outward in bands. B. New oceanic crust is formed at deep-sea trenches, pushed away from the trench, and destroyed at midocean ridges. C. New oceanic crust is formed at midocean ridges, pushed away from the ridge, and destroyed at deep-sea trenches. D. New oceanic crust is formed at seamounts and spreads outward in all directions.
It would be letter C - <span>New oceanic crust is formed at mid-ocean ridges, pushed away from the ridge, and destroyed at deep-sea trenches. </span> Seafloor spreading happens in the "mid-ocean ridges". In fact, the meaning of Seafloor spreading is that it is a process that occurs at mid-ocean ridges, where new oceanic crust is developed through volcanic activity and then slowly moves apart from the ridge.<span> </span>
New maritime hull is shaped at mid-sea edges, pushed far from the edge, and wrecked at remote ocean trenches. Ocean bottom spreading occurs in the "mid-sea ridges". truth be told, the significance of Seafloor spreading is that it is a procedure that happens at mid-sea edges, where new maritime hull is created through volcanic action and afterward gradually moves separated from the edge.
Highwall mining is often used when excavating an open-pit mine becomes too expensive. There are many advantages over underground mining, including the fact that it is both more cost-effective and involves less lead time.
