C. The polar vortex and tropical breezes
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.
Answer: B. Original Continuity
Explanation:
Original continuity is the concept that sediments are deposited horizontally at the original point of formation. This lateral deposit continues, layer by layer unless the sediments are interrupted by a barrier.
The two rocks on the opposite sides of the canyon were likely one body of rock due to their similar lithology and fossil content. It is likely that the canyon formed due to erosion over time, thereby creating a barrier between the rocks.
