An endothermic process is a chemical or physical process that absorbs heat from its surroundings. [1] In terms of thermodynamics and thermochemistry, it is a thermodynamic process with an increase in the enthalpy H (or internal energy U) of the system. [2] In an endothermic process, the heat that a system absorbs is thermal energy transfer into ...
Since the inflowing water can evacuate only through seepage or evaporation, dried minerals or other products collect in the basin, eventually making the water saline and also making the basin vulnerable to pollution. [7] Continents vary in their concentration of endorheic regions due to conditions of geography and climate.
Endorheic lake. An endorheic lake (also called a sink lake or terminal lake) is a collection of water within an endorheic basin, or sink, with no evident outlet. [1] Endorheic lakes are generally saline as a result of being unable to get rid of solutes left in the lake by evaporation. [2] These lakes can be used as indicators of anthropogenic ...
Students encounter a source of possible confusion between the terminology of physics and biology. Whereas the thermodynamic terms "exothermic" and "endothermic" respectively refer to processes that give out heat energy and processes that absorb heat energy, in biology the sense is effectively reversed.
Geomorphology (from Ancient Greek: γῆ, gê, 'earth'; μορφή, morphḗ, 'form'; and λόγος, lógos, 'study') [2] is the scientific study of the origin and evolution of topographic and bathymetric features generated by physical, chemical or biological processes operating at or near Earth's surface. Geomorphologists seek to understand ...
Physical geography (also known as physiography) is one of the three main branches of geography. [1][2][3][4][5] Physical geography is the branch of natural science which deals with the processes and patterns in the natural environment such as the atmosphere, hydrosphere, biosphere, and geosphere.
Hibernation. Hibernation is a state of minimal activity and metabolic depression undergone by some animal species. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It is most commonly used to pass through winter months – called overwintering.
Carbon sequestration is the process of storing carbon in a carbon pool. [2]: 2248 It plays a crucial role in limiting climate change by reducing the amount of carbon dioxide in the atmosphere. There are two main types of carbon sequestration: biologic (also called biosequestration) and geologic. [3] Biologic carbon sequestration is a naturally ...
