Answer to Question 1

B

Answer to Question 2

In general, the distribution of particle sizes moves from large to small composition as they move farther away from shore. Different size sediments are moved in various ways. Natural marine processes tend to sort the sediments by size.
Neritic sediments like sand are mostly terrigenous in origin. These larger particles are found close to shore. These can be formed by erosion on the land and brought to the continental shelf by rivers. This particle size is distributed by currents.
Silts and clays are found in deeper waters. These lightweight, small sediments are distributed by wave actions and currents. The finest of these sediments can stay in the water for decades before settling on the deep ocean floors. These particular sediments are moved by deep water currents.
Larger sediments can be transported to other sections of the continental slope via turbidity currents.
