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.
In physics, energy is a property of objects which can be transferred to other objects or converted into different forms, but cannot be created or destroyed.ll of the many forms of energy are convertible to other kinds of energy, and obey the law of conservation of energy which says that energy can be neither created nor be destroyed; however, it can change from one form to another.
