Rock formation, layering and composition, and the plant and animal fossil record, all help to form a time-line.
Geologists believe that the upper mantle portion of the asthenosphere is primarily heated by the residual heat left over from the formation of the Earth, known as radiogenic heat. This heat is generated by the decay of radioactive isotopes present in the mantle. Other sources of heat include the heat transferred from the core and the heat produced by ongoing mantle convection.

The school board agreed to the formation of a new committee. The troops marched in formation past the reviewing stand. The unusual rock formation on the mountain was of interest to geologists.
Sedimentary
the fundamental units of lithostratigraphy are supergroup,group,formation,member and bed.in these units formation is the key unit of lithostratigraphy.a formation consists of a certain number of rock strata that have a comparable lithology,facies or similar other properties

Geologists love sedimentary rock because the fossils give a quick reference to their date of formation and environment of deposition.
Uniformitarian geologists will use this method to determine which layer of rock formed at which time period of earth's history, and the order of the formation.

Mount Everest is made up of three formations. Geologists have named these, from the bottom to the summit respectively, the Rongbuk Formation, the North Col Formation and the Qomolangma Formation. Read the article in the link to find out what each formation is made of.
geologists believe the force may be caused by the collision of lithospheric plates.......
