The description of a place includes its physical and human characteristics. For example, you can describe both Denver and Miami in terms of their environments, climates, population sizes, industry, and architecture. In addition, places can be considered parts of different regions. You can draw a map that shows regions of low population and high population. You can divide the Earth according to rainfall or temperature.
Regions are simply ways of organizing our own descriptions of the world.
People's culture and experience influence their perceptions of regions. Physical processes constantly change Earth's surface. Physical processes also interact with living things, creating and modifying Earth's ecosystems. Weather systems, ocean currents, volcanic activity, and tectonic plate movement affect the landscape and the organisms within it. At the same time, living things release and absorb gases, build and use soil, break down rocks, dam streams, and fill in lakes.
