Detailed explanation-1: -The solar wind is created by the outward expansion of plasma (a collection of charged particles) from the Sun’s corona (outermost atmosphere). This plasma is continually heated to the point that the Sun’s gravity can’t hold it down. It then travels along the Sun’s magnetic field lines that extend radially outward.
Detailed explanation-2: -Solar flares are a sudden explosion of energy caused by tangling, crossing or reorganizing of magnetic field lines near sunspots. The surface of the Sun is a very busy place. It has electrically charged gases that generate areas of powerful magnetic forces. These areas are called magnetic fields.
Detailed explanation-3: -No, the solar wind and solar flares are not the same phenomena. As I said above, a solar flare is just an enhancement of electromagnetic radiation in the UV to -ray range (mostly UV and x-rays). The solar wind is the constant flow of thermal particles from the sun’s upper atmosphere.
Detailed explanation-4: -They do disturb the Earth’s ionosphere, however, which in turn disturbs radio communications. Along with energetic ultraviolet radiation, they heat the Earth’s outer atmosphere, causing it to expand.
