1 Without its atmosphere, Earth would be a very different planet. 2  Gases in the atmosphere allow plants to photosynthesize and animals and plants to engage in respiration. 3  Water vapor, which is an atmospheric gas, is an essential part of the water cycle. 4  All weather takes place in the atmosphere.
Energy transformation can also be explained in terms of potential energy, the stored energy of a system, which can be converted into kinetic energy, the energy of movement. For example, a roller coaster sitting at the top of a hill is said to have potential energy.
Because the law of conservation of energy states that energy is always conserved in the universe and simply changes from one form to another, many energy transformations are taking place constantly. Examples of Energy Transformations: 1. A toaster transforms electrical energy into thermal energy. 2. A blender transforms electrical energy into mechanical energy. 3. The sun transforms nuclear energy into ultraviolet, infrared, and gamma energy all forms of electromagnetic energy. 4.
