The surface-area-to-volume ratio has physical dimension inverse length (L −1) and is therefore expressed in units of inverse metre (m −1) or its prefixed unit multiples and submultiples. As an example, a cube with sides of length 1 cm will have a surface area of 6 cm 2 and a volume of 1 cm 3. The surface to volume ratio for this cube is thus
The lowering of a fluvial surface, such as a stream bed or floodplain, through erosional processes. dendrite A crystal that develops with a typical multi-branching tree-like form. Denudation The lowering of the earth's surface through chemical and physical weathering. deposition The geological process by which material is added to a landform or ...
The damage on the metal sheet or characteristic pattern illustrates an "uneven surface," a change in the sheet material's plastic behavior and involves a larger deformed volume compared to mere flattening of the surface oxides. Galling is a form of wear caused by adhesion between sliding surfaces.
This occurs when the volume of sediment carried by the river and deposited at its mouth exceeds the volume lost through subsidence, sea level rise, or coastal erosion. prominence 1. A conspicuous high point that projects above or beyond its surroundings, e.g. a butte or a promontory. [9] 2. See topographic prominence. promontory
This surface is extended through the continents (such as might be approximated with very narrow hypothetical canals). According to Carl Friedrich Gauss, who first described it, it is the "mathematical figure of the Earth", a smooth but irregular surface whose shape results from the uneven distribution of mass within and on the surface of Earth.

The totality of water in the solid phase on the Earth's surface, including glaciers; sea, lake, and river ice; snow; and permafrost. The cryosphere is sometimes considered a subset of the hydrosphere. [3] cryoturbation. Also frost churning. The mixing of materials from various horizons of the soil down to the bedrock due to freezing and thawing ...
an academic discipline – a body of knowledge given to − or received by − a disciple (student); a branch or sphere of knowledge, or field of study, that an individual has chosen to specialize in. Modern geography is an all-encompassing discipline that seeks to understand the Earth and its human and natural complexities − not merely where objects are, but how they have changed and come ...
Geography is subject to the laws of physics, and in studying things that occur in space, time must be considered. Time in geography is more than just the historical record of events that occurred at various discrete coordinates; but also includes modeling the dynamic movement of people, organisms, and things through space.
