Question

Quizplus · Accepted Answer

Foreset beds in a delta are inclined toward deeper water and are typically formed by the deposition of sediment that is transported and deposited by the river as it enters the delta region. These beds are typically cross-bedded, meaning that the layers of sediment are inclined to the horizontal, giving the delta its characteristic triangular shape. Backset beds (A) are inclined in the opposite direction and are typically formed in the more landward parts of a delta, whereas topset beds (B) are the horizontal or gently inclined layers of sediment that form on top of the foreset beds. Bottomset beds (D) occur in the most offshore parts of the delta and are typically composed of fine-grained sediment that settles out of suspension as the water slows down.
