The difference between natural and artificial sources of light is that natural sources are produced by the sun while artificial light sources illuminate using energy from other sources and include incandescent bulbs.
Natural sources : sun, firefly Artificial sources: oil lamps, tube lights
A primary light source is one that actually produces light, such as a light bulb or the sun. A secondary light source in one that ONLY reflects the light produced by a primary light source. It doesn't produce light itself, such as a mirror or the moon.
Sources of cloud condensation nuclei can be both natural and human-caused. Natural sources of cloud condensation nuclei include volcanic dust, sea spray salt, and bateria Humans also release unnatural chemicals into the air from the burning of fossil fuels and from industrial sources
Renewable sources are the sources that naturally replenish themselves. This is not the case with natural gas. Forms of renewable energy are the sun and wind energy. There is a new source for both at all times.

biofuels
this are tyes of energy created by men
natural energy sources
they are both natural sources of energy
It is a natural source of heat energy
Americium is an artificial element, a natural source doesn't exist.
There are natural and artificial light sources. A few examples of natural light sources include the Sun, stars, and candles. A few examples of artificial light sources include light bulbs, lamp posts, and televisions.
one natural resource is the sun
Those are usually called "lamps" or "light bulbs".
nonrenewable energy sources are sources that are depleted sources as fossil fuels (wood, coal, natural gas, and oil)
