Quiz on relative dating

This law allows a general age sequence to be established for layers or strata at a site or location.Socrative has been an integral part of my classroom for almost 4 years and I wanted to share the quizzes I have been using in my classroom.These specific required conditions explain why fossils are so rare. : The Making of the Biological Past Response: Since fossilization requires very unique circumstances, fossils are very rare.As a result, fossils do not necessarily provide a complete representation of the past.Response: The two major types of dating include relative methods and absolute methods.

Any living organism can become fossilized, including bacteria, plants, and animals.See Figure 8.13 Fluorine Dating Response: Fossils are the remains of deceased organisms that have become rock, enabling them to be preserved for thousands or millions of years.Inorganic materials, such as iron and silica slowly and steadily replace the organic materials, like calcium and phosphorus, in the organism.The chances of fossilization are very slim, because it requires that the remains be quickly buried and be kept in an oxygen-free environment.Scavenger and bacterial activity must be prevented so that decomposition is limited.Other relative methods include chemical dating, biostratigraphic or faunal dating, and cultural dating.Chemical dating, such as fluorine dating, compares the relative amounts of absorbed fluorine in bones from the same site.Fossils are found in a variety of rock, but most often in sedimentary rock, which forms from the accumulation of sediments.The replacement of organic materials with inorganic materials is not always complete, as DNA is sometimes preserved within the fossil.In addition, local climatic and environmental conditions determine whether fossilization will occur, so that there is differential preservation among different locations.Moreover, the rock sequences are not always complete in all places, so certain periods cannot be investigated.
