Geologists use the geologic time scale to show Earth’s history.. It is a record of the geologic events and the evolution of life forms as shown by the fossil record.. Mapping, spectroscopy and geologic analysis of Earth’s “sister” planet. Venus. The Basics, pre-1960. Radius 95% of Earth, mass 82%. 92X Earth atmospheric pressure, 97% CO2. 462°C surface temp.

For example, using fossils, geologists can compare certain geologic strata in Montana with the "type section" of Devonian age rocks in Devon, England and determine that their ages are the same. Radiometric dates tell us that Devonian rocks fall in a range of 369–410 million years ago.. In depth: chapter 19. Geologic Time Scale.

In the late 1700s, James Hutton began to question some of the ideas regarding the Earth.. He found fossils and saw them as evidence of life forms that no longer exist. . Different types of fossilized creatures were found in different layers of rock.. Faith, Reason, and Earth History. Chapter 14. by Dr. Leonard Brand. Short-age. Geology. Conventional. Geology.

Geologic field work can be loosely defined as the body of work necessary to:. Determine the spatial distribution, age and attitude of the rock types within an area. Section 12.1 Discovering earth’s history. Uniformitarianism – the idea that physical, chemical, and biological laws that operate today also operated in the past; the present is the key to the past..
