In which of the following environments would you expect lithogenous sediment to be the dominant sediment type?

Sandy Beach,at the base of the continental slope and muddy lagoon.

Explanation: Lithosphere is the solid portions of the Earth,made up of the mountains,rocks,the highlands etc.

Lithogenous sediments are sediments formed as a result of the breakdown of rocks into small pieces and particles. They are also formed through Earth quakes and vulcanic eruptions. Lithogenous sediments can be found in areas such as in Sandy Beach ( containing weathered rocks),at the base of continental slopes and in muddy lagoons.

continental margins, muddy lagoons, sandy beaches, deep oceans.

Explanation:

Lithogenous sediments are sediments whose mineral grains are formed during the weathering of rocks, this sediments are transported by agents such as force of gravity, wind action, running water and movement of ice.

Lithogenous sediments are the most abundant sediments on the earth crust, example includes glacial marine sediments, abyssal clays etc. These sediments are composed of quartz, clay, and other rock fragments. They are found widely distributed along the continental margins, deep oceans, sandy beaches, muddy lagoons, etc.
