Geographical feature


Geographical features are man-made or naturally-created features of the Earth.

Natural geographical features consist of landforms and ecosystems. For example, terrain types, physical factors of the environment) are natural geographical features. Conversely, human settlements or other engineered forms are considered types of artificial geographical features.

There are 2 different terms to describe habitats. An ecosystem is a community of organisms interacting with its environment. In contrast, biomes occupy large areas of the globe and often encompass many different kinds of geographical features, including mountain ranges.

One conceptual definition of an ecosystem is: "Any unit that includes all of the organisms (the 'community') in a given area interacting with the physical environment so that a flow of energy leads to clearly defined trophic structure, biotic diversity, and material cycles (exchange of materials between living and nonliving parts) within the system."

One conceptual definition of a biome is "a kind of ecosystem, desert, a tropical rain forest, or a grassland." A biome is "classified according to the predominant vegetation and characterized by adaptations of organisms to that particular environment." It is a "geographically-defined area of ecologically similar communities of plants, animals, and soil organisms, often referred to as ecosystems." Biomes are defined based on factors such as plant structures (such as trees, shrubs, and grasses), leaf types (such as broadleaf and needleleaf), plant spacing (forest, woodland, savanna), and climate. Unlike ecozones, biomes are not defined by genetic, taxonomic, or historical similarities. Biomes are often identified with particular patterns of ecological succession and climax vegetation.

A landform comprises a geomorphological unit, and is largely defined by its surface form and location in the landscape, as part of the terrain, and as such is typically an element of topography. Landforms are categorized by features such as elevation, slope, orientation, stratification, rock exposure, and soil type. They include berms, mounds, hills, cliffs, valleys, rivers and numerous other elements. Oceans and continents are the highest-order landforms.
