What type of sediment particles are similar in size?

a. sorted

b. unsorted

c. clastic

d. dissolved

A. Sorted sediment particles are similar in size

Explanation:

Sorting means the degree of resemblance of the rock. It depends upon how much transport the sediment has undergone. Well sorted grains have rocks of similar size. Spiky sediments are found closest to the source area because they are heavy and big, while fine sediments like clay and silt travel the farthest. The "degree of sorting" indicates the energy and time taken for the "deposition" as well as the "transport process".  

yes? sounds right, but you didn’t ask a question.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
