Geology

The word geology comes from the Greek word geo meaning earth and logy which means "the study of." It is the study of the origin, history, and structure of the earth. This is usually taken to mean the formation of the fossil record or geologic column and other major features like mountains, rivers, lakes and the erosion that bodies of water cause as well as similar natural features of earth.

History and Development

One of the most prominent geologic thinkers was Niels Steensen (1638–1686) who was responsible for the development and observation of superposition. The term superposition describes the process of sedimentary rock deposition in a successive, mainly horizontal fashion. In his book entitled, Forerunner (1669) Steensen implied a roughly 6,000-year-old Earth and that fossils within the rock strata laid down through superposition were deposited by Noah’s Flood. The century after Seensen's death saw several prominent authors stand firm in the principles put forth in Steensen's book. The English geologist John Woodward (1665–1722) and the German geologist Johann Lehmann (1719–1767), to name a few, wrote books ultimately reinforcing that view.[1]

The idea of an old earth is based on the principle of uniformitarianism, which is the doctrine that geologic processes have acted in the same regular manner and intensity throughout geologic time. This concept was begun in 1795 by James Hutton and further developed by Charles Lyell who is considered the father of modern geology. Charles Darwin took Lyell's book "Principles of Geology" during his historic voyage on the Beagle. Lyell's book inspired Darwin to form his theory of slow biological change known as gradualism.

Principles of Geology

There are two main components of geologic science which are historical geology and physical geology. Within creation science it provides clear evidence of the global flood of Noah, which strongly supports a young earth and goes against the long ages the theory of evolution assumes.

Physical geology

The study of the materials that make the various rock formations and structures of earth and the processes or mechanisms that shape them.

Historical geology

The study of earth's history with the study of sedimentary rocks, their relation in geologic time and the study of fossils and locations within the rocks.[2]

Principles of Stratigraphy

Stratigraphy is the study of rock strata, especially the distribution, deposition, and age of sedimentary rocks. William Smith advanced stratigraphy around 1815 when he mapped out strata of England and drew a geological map that is almost unchanged today.[3]

Superposition

Main Article: Principle of superposition

The principle of superposition, now known as the scientific law of superposition, is an axiom that forms one of the bases of the sciences of geology, archaeology, and other fields dealing with stratigraphy. It was first put forth in the 17th century by the Danish scientist Niels Steensen.

Continuity

Main Article: Principle of continuity

Strata are formed from sediments in a fluid. Therefore, when any stratum forms it must be bordered on its sides by another solid body, or else, the sediments will continue around the earth.

Original horizontality

Main Article: Principle of original horizontality

When a stratum is formed, the lower surface and surfaces of its sides, corresponded with the surfaces of the adjacent bodies. The upper surface was parallel to the horizon, as far as that is possible. With the exception of the lowest stratum, all the strata were contained in two parallel planes to the horizon and were at one time parallel to the horizon.
