Define well-sorted and poorly sorted sediments. What is expected on the deep ocean floor? Which is
found close to shore? Include information about the energy associated with each and the avenues of
transportation of these sediments. What will be an ideal response?
ANS:Answer
should include:
? Well-sorted sediments are dominated by one particle size. Poorly sorted sediments are a
mixture of sizes.
? Well-sorted sediments are commonly found in the deep ocean. This is due to narrow
changes in energy at these depths.
? Well-sorted sediments in the deep ocean are transported by ocean currents.
? Poorly sorted sediments tend to be close to shore. They occur in areas with high erosion
rates because of the high energy fluctuations. The erosion and wave action creates many
different particle sizes.
? Poorly sorted sediments are transported by turbidity currents.
