What are the basic differences between the disciplines of physical and historical geology? A. physical geology involves the stud
alexandr402 [8]

Answer:

D. historical geology involves the study of rock strata, fossils, and geologic events, utilizing the geologic time scale as a reference; physical geology includes the study of how rocks form and of how erosion shapes the land surface

Explanation:

The geology can be separated into two sub-disciplines; physical geology and historical geology. The physical geology is the part of geology that has the present in its focus. It is examining the formation of the rocks, the volcanic eruptions, the earthquake activities, and even the effects of the pollution. On the other side, the historical geology is focused on the past. This part of the geology uses the geological time scale as its reference. It is examining the layers of the rocks, and through it tries to explain what happened in the past, how were the geological processes working. Also, the fossils are one of the main focuses because they provide lot of information about the environment in which they lived.

Description of water pollution
umka21 [38]
Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans, aquifers and groundwater). This form of environmental degradation occurs when pollutants are directly or indirectly discharged into water bodies without adequate treatment to remove harmful compounds.

Water pollution affects the entire biosphere – plants and organisms living in these bodies of water. In almost all cases the effect is damaging not only to individual species and population, but also to the natural biological communities.
