Answer:

The correct option is B. all the same approximate size

Explanation:

The sorting of sediments is the distribution of the particles or the grains of the sediments on the basis of the grain size. The sediments are classified into the following categories on the basis of their grain size : very poorly, poorly, moderately , well and finally, very well sorted.

The sorting is quantified by using the Inclusive Graphic Standard Deviation represent by \sigma _{I}

For a well-sorted layer of sediment, the Inclusive Graphic Standard Deviation is:

0.35 < {\displaystyle \sigma _{I}} < 0.50 ,  diameter (phi units)

Therefore, in a well-sorted layer of sediment, all the grains will be of the same approximate size.

Pavel [41]

Answer:

The benefits of playing shooter-type video games

Explanation:

Shooter type video games are designed to develop the concentration of the player especially young people who are still in developing stage. But these games are making them violent and rash due to the way the games are structured . For example a game has shooter hunting in forests with loaded guns in hands. This only gives the player much more scope to turn violent and aggressive. The main aim of concentration development is kept aside . So these games are really a threat for adolescents and must be at least designed in a subtle manner .
