Law of conservation of energy express that energy can neither be created nor destroyed; it can only be transformed or transferred from one form to another. In this case, The Sun is a source of energy that controls the circulation of the atmosphere. The Sun emits energy in the form of electromagnetic radiation, where a part is intercepted by the Earth-atmosphere system and converted into other forms of energy, such as heat and kinetic energy.
Solar energy is distributed on Earth, and responsible by the oceanic winds, that transport the heat from the tropics to the poles, to achieve an energy balance. These causes reside in the movements of the Earth in relation to the Sun, and also in variations in the surface of the Earth.
Well I actually thought it was an option for students to make up their own mind on when they want to go to college. Some students receive scholarship of a subject they passed with high Honor's, so they probably go away to college right away. Some students have good paying jobs so they don't want to go off to college right away.
