Question

a normally graded deposit (associated with water decreasing in turbulence) is
consistently shelly sediments throughout
coarse on the bottom and finer moving up
fine on the bottom and coarser moving up
consistently coarse sediments throughout
randomly mixed coarse and fine deposits throughout

Explanation:

Normally graded deposits form when water turbulence decreases over time. Heavier, coarser sediment settles first at the bottom, while finer, lighter sediment settles later as turbulence weakens, creating a pattern of coarse material below and finer material above.

Answer:

coarse on the bottom and finer moving up
