(For further examples, Moon, for example, provided scientists with firsthand information on lunar geology, including observations on such features as meteorite craters that are relatively rare on Earth.Unmanned space probes have yielded significant data on the surface features of many of the planets and their satellites.This is the science of geochronology, which in recent years has revolutionized scientific perception of Earth history and which relies heavily on the measured parent-to-daughter ratio of radiogenic isotopes ().Paleontology is the study of fossils and is concerned not only with their description and classification but also with an analysis of the evolution of the organisms involved.Knowledge of the processes of interaction of the atmosphere and the hydrosphere with the surface rocks and soils of the Earth’s crust is important for an understanding not only of the development of landscapes but also (and perhaps more importantly) of the ways in which sediments are created.This in turn helps in interpreting the mode of formation and the depositional environment of sedimentary rocks.Analyses of fracture-filling bitumen showed that it had very elevated Nd ratios.

As a discipline, mineralogy has had close historical ties with geology.

Thus the discipline of geomorphology is fundamental to the uniformitarian approach to the Earth sciences according to which the present is the key to the past.
