Geochronology Geochronology is the science of determining the age of rocks, fossils, and sediments using signatures inherent in the rocks themselves. Absolute geochronology can be accomplished through radioactive isotopes, whereas relative geochronology is provided by tools such as palaeomagnetism and stable isotope ratios.

Meteorology Meteorology is the interdisciplinary scientific study of the atmosphere. The study of meteorology dates back millennia, though significant progress in meteorology did not occur until the 18th century. The 19th century saw modest progress in the field after weather observation networks were formed across broad regions. Prior attempts at prediction of weather depended on historical data.

Tephrochronology Tephrochronology is a geochronological technique that uses discrete layers of tephra—volcanic ash from a single eruption—to create a chronological framework in which paleoenvironmental or archaeological records can be placed. Such an established event provides a tephra horizon.

Geomancy Geomancy (Greek: γεωμαντεία, earth divination) is a method of divination that interprets markings on the ground or the patterns formed by tossed handfuls of soil, rocks, or sand. The most prevalent form of divinatory geomancy involves interpreting a series of 16 figures formed by a randomized process that involves recursion followed by analyzing them, often augmented with astrological interpretations.

- Weathering & Erosion - Introduction to Geomorphological Processes. Geomorphology is the study of the nature and origin of landforms, particularly of the formative processes of weathering and erosion that occur in the atmosphere and hydrosphere. These processes continually shape the Earth's surface, and generate the sediments that circulate in the Rock Cycle.

Geochronology Geochronology: Geochronology, field of scientific investigation concerned with determining the age and history of Earth’s rocks and rock assemblages. Such time determinations are made and the record of past geologic events is deciphered by studying the distribution and succession of rock strata, as well as the character of the fossil organisms preserved within the strata.

Geomorphology For other uses, see Physiographic regions of the world. Surface of the Earth. Geomorphology (from Greek: γη, ge, earth; μοϝφή, morfe, morfé; form and, λόγος, logos) knowledge is the scientific study of landforms and the processes that shape. themodern geomorphology focuses on the quantitative analysis of interconnected processes, such as the contribution of solar energy, the rates of steps of the hydrologic cycle, plate movement rates from geophysics to compute the age and expected fate of landforms and the weathering and erosion of the land.

Geochronometry vs Geochronometer - What's the difference? As nouns the difference between geochronometry and geochronometer is that geochronometry is (geology) the science of the measurement of the age of rocks etc based on the radioactive decay of naturally occurring isotopes while geochronometer is (geology) any device used to measure geologic time, especially by measuring radioactive decay, or the relative abundance of isotopes.

- 1 Uranium-lead dating. 2  This technique measures the ratio of two lead isotopes (lead-206 and lead-207) to the amount of uranium in a mineral or rock. 3  Often applied to the trace mineral zircon in igneous rocks, this method is one of the two most commonly used (along with argon-argon dating) for geologic dating.eochronology is the science of determining the age of rocks, fossils, and sediments using signatures inherent in the rocks themselves. Absolute geochronology can be accomplished through radioactive isotopes, whereas relative geochronology is provided by tools such as palaeomagnetism and stable isotope ratios.
