The terms "natural environment" and "physical environment" are related but are not exactly the same.
-
Natural Environment: This refers to all living and non-living things occurring naturally, typically including ecosystems, landscapes, flora, fauna, air, water, and soil. It encompasses everything that is formed by nature without human influence, such as forests, rivers, mountains, and oceans.
-
Physical Environment: This term is broader and can refer to the physical surroundings in which organisms live, which may include both natural and built environments. It encompasses the natural environment but also includes man-made structures and features, such as buildings, roads, and urban spaces. The physical environment generally refers to all physical aspects of the world, including the atmosphere, hydrosphere, lithosphere, and biosphere.
In summary, while the natural environment is a subset of the physical environment, the physical environment includes both natural and human-made elements.
