Define relative dating geology
Relative dating is different from absolute dating in which specific dates are assigned to geologic events (we will discuss absolute dating techniques later).
(light brown) Next, fossil-rich sedimentary rocks were precipitated.
(dark brown) Flat lying sedimentary rocks were eventually precipitated.
The secondary rocks were thought to include interlayered basalts, which Werner thought formed by combustion of buried coal layers.
Hutton viewed tilted strata as having been initially deposited horizontally, and then were subsequently deformed (tilted and folded) by the forces of Earth's internal heat engine.
Geologists generally know the age of a rock by determining the age of the group of rocks, or formation, that it is found in.
An absolute age is one determined usually by mass-spectrometry where an isotope is measured and then an age can be calculated (a very very basic explanation).
After millions of years, geologic movements or excavations bring the fossil to the surface (4).We can absolute date materials but it will always have an uncertainty range, we can never know the age with infinite precision.
