Question

When wind and running water gradually decrease in velocity, the transported sediments are deposited

(1) all at once, and are unsorted
(2) all at once, and are sorted by size and density
(3) over a period of time, and are unsorted
(4) over a period of time, and are sorted by size and density

Answer 1

When wind and running water gradually decrease in velocity, the transported sediments are deposited over a period of time, and are sorted by size and density. This is because as the velocity decreases, sediments or rocks will accumulate resulting to variety of sizes and a change in density.
