I came here to study <a href=" http://newdaypost.com/politics ">viagra cialis levitra uk</a> Below the surface of the sun, the charged material, the plasma, is flowing. Magnetic loops emerge from this flow and set up areas of positive magnetic poles lying next to negative ones. The loops arc up over the sun from one polarity to the other. As the sun's material continues to flow under the surface, the positive and negative poles slip past each other – not unlike tectonic plates on Earth slipping past each other – though on the sun, of course, the material is a hot gas, not hard rock. This causes the arcs above to grow, twist sideways and become more unstable. The very act of that slippage, or shear, puts more energy into the system, coiled and waiting to spring, like twisting up a rubber band before letting it loose. Eventually the magnetic field lines in the arcs buckle inward, touch and reconnect, while giving off a bright flash as the energy releases, sending radiation and energetic particles out into space. |
