Question

Quizplus · Accepted Answer

Abyssal plains are covered by thick layers of sediment that accumulate over time, resulting in a very flat topography. Basalt volcanoes can also contribute to a flat surface by producing relatively little terrain, but it is the sediment accumulation that is the primary cause of the flatness. The option A is incorrect because there is data available to show that the abyssal plains are flat. Option B is partially correct but not the primary reason for the flatness. Option D is incorrect because the faults are not responsible for the flatness of the abyssal plains.
