Question

At a flow velocity of 12 cm/sec, which of the following statements are true?

Multiple select question.
a) Most sand sizes are transported as bedload.
b) Silt is transported as bedload.
c) Gravel is transported as bedload
d) Clay is transported as suspended sediment.

Answer 1

Most sand sizes are transported as bedload, while clay is transported as suspended sediment at a flow velocity of 12 cm/sec.

Step-by-step explanation:

At a flow velocity of 12 cm/sec, the following statements are true:

a) Most sand sizes are transported as bedload: Bedload refers to the sediments that are transported along the bottom of the river or stream. Sand particles are larger and heavier, so they tend to be transported as bedload.

d) Clay is transported as suspended sediment: Clay particles are much smaller and lighter, so they can be easily carried in suspension by the flow of water.

Therefore, options a and d are the true statements.
