Examples of natural and artificial bodies.

In nature, there are two types of objects or bodies: natural and artificial. The first ones were created exclusively by nature. Man did not participate in their creation. These include the sun, moon, our planet, rivers, oceans, seas, continents, stars and many, many others. Artificial bodies are always created with the direct participation of humans – these are reservoirs, canals, artificial islands, various machines, devices and equipment. In general, everything that man has created is an artificial body.
