Historical geology usually refers to the study of the changes and the variation that occurs at or below the surface of the earth. In simple words, it mainly involves the study of past events. This includes the variation and evolution of different life forms that existed on earth over a time of about 3.8 billion years until the present. It basically comprises the important part of geology namely Paleoclimatology, Paleontology and Paleoseismology. This historical geology is also known as Paleogeology.
Thus, historical geology involves the biological changes that occur over a definite time.
Thus, the correct answer is option (D).
Hydraulic fracturing using high pressure liquids to break rocks can be used to access deep reservoirs of <u>crude oil. </u>
<h3>What is the use of hydraulic fracturing?</h3>
In a process known as fracking, hydraulic fracturing is done when a fluid is injected into rocks far below the surface.
The aim of this process is to get the rocks to break apart which would then allow the deep reserves of oil to be accessed. This is a major process of crude oil production in the United States.
