Question

Graded bedding, as shown in the image below, is characteristic of which of the following geologic environments or processes?

1) glacier
2) beach
3) marsh
4) turbidity current
5) playa lake

Answer 1

Graded bedding is characteristic of a turbidity current, which is an underwater avalanche of sediment. It represents depositional environments in which transport energy decreases over time.

Step-by-step explanation:

Graded bedding, as shown in the image, is characteristic of a turbidity current. Graded bedding is a sedimentary structure where a change in grain size can be observed within a single bed. It typically represents depositional environments in which transport energy decreases over time. Turbidity currents are underwater avalanches of sediment that move downslope and deposit sediment with graded bedding.
