Fire is created through quantum reactions with the air. The air excites the molecules and they emit photons, which are what we see when we look at flames.Continue Reading
Fire has been used for around 1 million years for cooking food in a controlled manner and for lighting. Candle flames burn at about 1000 degrees Celsius but the color of the flame depends on the substance being burned. Calcium provides a red flame; sodium delivers a yellow flame and barium gives a greenish flame.
Fire requires heat, oxygen and and fuel to burn. Though wildfires can be quite dangerous in many circumstances, controlled burning is used for burning down brush in forests to stimulate ecological growth.Learn more about Earth Science
Moving air is called wind. Winds are caused by differences in air pressure but can be modified by the Coriolis effect and friction. The movement of winds is generally horizontal, but it can take on a vertical component in a thunderstorm.Full Answer >
Wind energy is created when moving air causes a wind turbine to rotate, powering a motor that generates electricity. The energy of the wind itself derives from differential heating of the air by the sun and the rotation of the Earth, combined with landscape features which shape the air flow. In this way, wind power is an indirect form of solar power.Full Answer >
Non-living things in the desert are water, air, energy, substrate and chemical constituents, also known as nutrients. The non-living elements combined with the living organisms make up the desert ecosystem.Full Answer >
Rainbows form when water in the air reflects and refracts sunlight and disperses the normally white sunlight into colored light. White light is composed of colored light that bends at different angles when reflected and refracted, separating the white light into the distinct colors of a rainbow.Full Answer >
