Solved by a verified expert:1…Describe the hypothesis of sea floor spreading (briefly). What is the basicdifference between continental drift theory and the plate tectonics theory?2…List and briefly describe the three types of plate boundaries?3… How does ocean crust form along a mid-ocean ridge?4…Study of depositional environments is critical to understanding Earth history.Relate these sedimentary rocks (sandstone, shale, limestone) to the generaldepositional environment such as beach, lake, wetland, shallow marine oyster shellbeds. How does depositional environmental energy and source material relate tothe sedimentary rock (such as sandstone or shale)?5…Explain the difference between of relative age dating and absolute (radiometricage) dating. What are the limitations (if any) of each? If you needed to establish adate for a fossil of probably Paleozoic Era would you use C-14 methods? Why orwhy not?6… Consider an exposed sedimentary rock formation (such as a shale, limestone,sandstone layered) on the side of highway, for instance, in Maryland. How doesthe regional climate influence weathering of those rocks?7… What are the three major topographic provinces of the ocean floor? What isthe continental margin? Distinguish between continental margin physiographicareas: continental rise, shelf and slope. How do the different parts of the oceanfloor (abyssal plain, ocean ridge, ridge flank regions) differ from each other?9…Briefly, explain the concept of ‘uniformitarianism’ and the principles of lateralcontinuity, superposition, and cross cutting relations that allow us to determine therelative ages of geologic events.10… What is a fossil? Give examples of three (3) types. What are processes thatcan yield (allow development) of fossils? Is the fossil record complete? Why orwhy not?EACH QUESTION HAS TO BE ANSWERED IN TWO PARAGRAPH AND SITE THE SOURCES.
