Some isotopes, however, decay slowly, and several of these are used as geologic clocks. Dating rocks by these radioactive timekeepers is simple in theory, but the laboratory procedures are complex. <span>All methods rely on the fact that certain elements (particularly uranium and potassium) contain a number of different isotopes whose half-life is exactly known and therefore the relative concentrations of these isotopes within a rock or mineral can measure the age.</span>
The biggest difference is the cause. The solar wind is a constant flow of particles from the sun's corona due to their high energy gained from the sun's interior, it's like being boiled off. CME's and flares are the result of “explosive” releases of energy from the sun's magnetic field. Solar flares and solar winds originate within the sun's atmosphere, but differ greatly from one another. Satellites on Earth and in outer space allow a look at solar flares, but you cannot see solar winds directly. However, the effects of solar winds reaching Earth appear to the naked eye when the aurora borealis and aurora australis electrify the night sky.
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy!
The answer is "Groundwater"
