Explain relative dating
Between the years of 17, James Hutton and William Smith advanced the concept of relative dating.
Hutton, a Scottish geologist, first proposed formally the fundamental principle used to classify rocks according to their relative ages.
Uniformitarian geologists began using the principles of stratigraphy to assign dates to the layers of the geological column fossils back in the late 1700s.
Relative dating uses a combination of fossil studies and structural interpretation to draw conclusions about the geological history of an area.
He concluded, after studying rocks at many outcrops, that each layer represented a specific interval of geologic time.
Further, he proposed that wherever un-contorted layers were exposed, the bottom layer was deposited first and was, therefore, the oldest layer exposed; each succeeding layer, up to the topmost one, was progressively younger.

During the same interval of time in another part of the world, the land surface subsided and was covered by the seas.These layers are presumed to be the result of annual fluctuations in climate, and using this method, uniformitarians purport to document ages of over 100,000 years.Creationists, such as Michael Oard, contend that these laminations are from subannual events, including layering due to dust to be found in a post-flood ice age. Subannual formation is supported by observations that several such layers of snow and ice can result from the storms within a single winter season.Relative dating is a dating method that used to determine determine the relative ages of geologic strata, artifacts, historical events, etc.This technique does not give specific ages to items.
