The ultimate goal of science is to understand the natural world in terms of scientific theories, which are only concepts. The word 'theory' refers to a speculative idea. A theory can't claim the truth or fact- they are simply reasons. I'll briefly answer your questions. How is Light created?... Light is energy. At the atomic level, light are photons which are a quantum of the electromagnetic field. Photons are produced whenever charged particles are accelerated.This light is produced (in our solar system) from the sun. The sun is a massive ball of burning gases, hence this produces energy and photons are emitted, as a reaction product. How are trees created?... from DNA at conception, sexually reproduce either via assissted pollination or self-pollination. How is dirt created? dirt is the by-product of erosion and weathering through the geohydrological cycle. To put simply-dirt is eroded rock. Rock comes from the lithosphere, where it's chemical properties, shape form, type, and composition is determined by plate tectonics. If evaporation happens everyday, why are there clouds sometimes in some areas and not there at other times?? Because moisture in the atmosphere is continuously imbalanced. Warm air massess and cool air masses are always moving and interacting. This happens by warm/cold fronts, orographic lift, and by convection caused by diurnal heating. why does the sea stop at the sand (no matter how rough the sea is)? the sea stops at the sand because that is the global sea level. It rises and lowers due to tides. It also changes due to global climate conditions ie. glaciation/melting process (otherwise known as global cooling/warming). how are clouds created?... Clouds are a mass of condensation droplets or ice crystals suspended in the atmosphere. The air is cooled to its saturation point. This happens when the air comes in contact with a cold surface or a surface that is cooling by radiation, or the air is cooled by adiabatic expansion (rising). Also the air stays the same temperature but absorbs more water vapour into it until it reaches saturation.
