Insulation system. The electrical insulation system for wires used in generators, electric motors, transformers, and other wire-wound electrical components is divided into different classes by temperature and temperature rise. The electrical insulation system is sometimes referred to as insulation class or thermal classification.
v. t. e. Advanced Placement ( AP) Human Geography (also known as AP Human Geo, AP Geography, APHG, AP HuGe, AP HuG, AP Human, HuGS, or HGAP) is an Advanced Placement social studies course in human geography for high school, usually freshmen students in the US, culminating in an exam administered by the College Board.

Climate change. Changes in surface air temperature over the past 50 years. [ 1] The Arctic has warmed the most, and temperatures on land have generally increased more than sea surface temperatures. Earth's average surface air temperature has increased almost 1.5 °C (about 2.5 °F) since the Industrial Revolution.
A choropleth map that visualizes the fraction of Australians that identified as Anglican at the 2011 census. The selected districts are local government areas, the variable is spatially intensive (a proportion) which is unclassed, and a part-spectral sequential color scheme is used. A choropleth map (from Ancient Greek χῶρος (khôros ...
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 data.
For a doubling of greenhouse gas concentrations, the global mean temperature would rise by about 2.5–4 °C (4.5–7.2 °F). [28] If emissions of CO 2 stopped abruptly and there was no use of negative emission technologies, the Earth's climate would not start moving back to its pre-industrial state. Temperatures would stay at the same high ...
Altitudinal zonation. Altitudinal zonation (or elevational zonation[ 1]) in mountainous regions describes the natural layering of ecosystems that occurs at distinct elevations due to varying environmental conditions. Temperature, humidity, soil composition, and solar radiation are important factors in determining altitudinal zones, which ...
Possibilism in cultural geography is the theory that the environment sets certain constraints or limitations, but culture is otherwise determined by social conditions. [ 1][ 2] In cultural ecology, Marshall Sahlins used this concept in order to develop alternative approaches to the environmental determinism dominant at that time in ecological ...
