Which example is a type of non-point source pollution?
a.
untreated chemicals from a factory
b.
runoff mixing with pesticides and debris
c.
toxic gases from a power plant
d.
garbage or leftover food from a restaurant

B.  runoff mixing with pesticides and debris

Explanation:

A non-point source pollution is the one which originates from many sources of origin but the source of their origin cannot be traced back to their origin. As a result of this, this kind of pollution cannot be controlled.

B.  runoff mixing with pesticides and debris is the correct option this is because of the fact that surface runoff (water) will take away pesticides and debris from their site of origin and discharge them to a water body or any other location. The source of these pesticides and debris cannot be traced back. Hence, it a type of non-point source pollution.

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.
