Describe how geographic concepts help to explain the distribution of phenomena on Earth.....PLEASE HELP!!​
inessss [21]

Spatial concepts help to explain the distribution of phenomena on Earth.

<h3>What is Spatial concepts in geography?</h3>

Spatial concepts provide a language for explaining the configuration of individuals, places, and environments. Arrangements can be represented in terms of proximity, distance, scale, clustering, distribution, etc.

Geographic concepts permit the exploration of relationships and connections between individuals and both natural and cultural environments. They include a spatial component. They furnish a framework that geographers utilize to interpret and symbolize information about the world.

Geography's unique method of understanding the world exists through spatial patterns and associations. A geographer visualizes and analyses spatial associations between objects i.e. they utilize notions such as location, distance, direction, shape, and pattern.

Spatial distribution in statistics exists in the arrangement of a phenomenon across the Earth's surface and a graphical display of such an interpretation exists as an essential tool in geographical and environmental statistics.

Hence, Spatial concepts help to explain the distribution of phenomena on Earth.
