Reconstructions of global temperature of the past 2000 years, using composite of different proxy methods. In the study of past climates ("paleoclimatology"), climate proxies are preserved physical characteristics of the past that stand in for direct meteorological measurements [1] and enable scientists to reconstruct the climatic conditions over a longer fraction of the Earth's history.
Paleoclimatology uses a variety of proxy methods from Earth and life sciences to obtain data previously preserved within rocks, sediments, boreholes, ice sheets, tree rings, corals, shells, and microfossils. Combined with techniques to date the proxies, the paleoclimate records are used to determine the past states of Earth's atmosphere.
This glossary of geography terms is a list of definitions of terms and concepts used in geography and related fields, including Earth science, oceanography, cartography, and human geography, as well as those describing spatial dimension, topographical features, natural resources, and the collection, analysis, and visualization of geographic ...
Fluid inclusions trapped in veins and minerals have been used as a proxy to explore the deformation history in orogenic belts. [11] As fluid activities are considerably more in shear zones in an orogenic belt, the fluid inclusions in a shear zone have been also used to explore the seismic activities during the evolution of the shear zone.

Exposure dating uses the concentration of exotic nuclides (e.g. 10 Be, 26 Al, 36 Cl) produced by cosmic rays interacting with Earth materials as a proxy for the age at which a surface, such as an alluvial fan, was created. Burial dating uses the differential radioactive decay of 2 cosmogenic elements as a proxy for the age at which a sediment ...

Annals of the Former World is a book on geology written by John McPhee and published in 1998 by Farrar, Straus and Giroux. [1] It won the 1999 Pulitzer Prize for General Nonfiction. [2] The book presents a geological history of North America, and was researched and written over the course of two decades beginning in 1978.
