Definition of relief and elevation

The relief represents the vertical change in elevation in a landscape, while the elevation represents the vertical distance from the sea level.

Explanation:

The term relief is often used in geography, especially physical geography, and it is a term that refers to the vertical change of elevation in a landscape. This aspect of geography is very important as the relief is detrimental for numerous process and activities, wherein some cases it is suitable for a lot of things, while in other it is a natural barrier. The relief consists of mountains, hills, plateaus, plains, canyons, gorges, etc.

The elevation, on the other hand, represents the vertical distance from sea level. Basically, from the point of the sea level that is taken as the basis for measurement, to any point on land, the vertical distance gives us the elevation. There is a great range in elevation from place to place, with some places being below sea level (thus in -), others being just a few meters above, and others being several km higher.

a maximum–minimum thermometer. the scales are fahrenheit on the inside of the u and celsius on the outside. the current temperature is 23 degrees celsius, the maximum recorded is 25, and the minimum is 15, both read from the base of the small markers in each arm of the u tube. the bulbs are hidden by a plastic housing.

six's thermometer is a registering thermometer which can record the maximum and minimum temperatures reached over a period of time, for example 24 hours. it is used to record the extremes of temperature at a location, for instance in meteorology and horticulture. it was invented by a british scientist james six, born in canterbury, in 1780; [1] the same basic design remains in use.

it is also commonly known as a maximum–minimum, minimum–maximum, maxima–minima or minima–maxima thermometer, of which it is the earliest practical design.

the thermometer indicates the current temperature, and the highest and lowest temperatures since last reset.
