Question

Quizplus · Accepted Answer

Lahars are fast-moving mixtures of volcanic debris, water, and sediment that flow down the slopes of a volcano during an eruption or soon after. They are directly related to volcanic activity and are unlikely to occur in regions without volcanoes. Therefore, option A is the best choice.

B) Rockfalls and D) Avalanches could potentially occur in regions without volcanic activity, as they are related to the geological structure of the area and not necessarily tied to volcanic activity.

C) Submarine mass movements involve the movement of sediment and rock on the seafloor, and while they can be caused by underwater volcanic activity, they can also be caused by other factors such as earthquakes or changes in water pressure. Therefore, this option is not exclusively related to volcanic activity.
