Answer:
Options (A), (B), and (D)
Explanation:
The lithogenous sediments are usually defined as those sediments that are produced from the weathering and erosion of rocks. These sediments are then transported from one place to another by agents such as wind, water, and ice. These are the most common sediments that are found on earth.
These sediments are of variable sizes, ranging from fine-grained sediments to coarse-grained and they are abundantly found in the sandy beaches, abyssal plains and at the base of the continental slope.
The rocks at the beaches are continuously hit by the sea waves that break down and carry the sediments seaward. These sediments along with the other terrestrial sediments are deposited on the abyssal plains and base of the continental slope.
Thus, the correct answers are options (A), (B), and (D).

Explanation: A dune is a mound of sand formed by the wind, usually along the beach or in a desert. Dunes form when wind blows sand into a sheltered area behind an obstacle. Dunes grow as grains of sand accumulate. Every dune has a windward side and a slipface.
