Sunspots occur where the sun's magnetic field loops up out of the solar surface and cool it slightly, making that section less bright. These disturbances in the sun's magnetic field make the sunspot about 2700°F (1500°C) cooler than the surrounding area.

They are caused by intense magnetic activity, which inhibits convection(a mode of heat transfer) by an effect comparable to the eddy current brake, forming areas of reduced surface temperature.

Alpha wins by a mile in terms of momentum . An Alpha particle is two protons plus two neutrons. A Beta particle is just a fast electron and Gamma is a high energy photon. As an Alpha particle is charge 2+ it is very easily stopped by just about any matter.

the alpha is massive compared to the beta and gamma, and the beta is more massive than the gamma, so more momentum is transfered from the heavier particles to atoms encountered along the path. Gamma is seen as the fastest and most highly penetrating, but alpha is the most strongly ionising.

Alpha particles usually have most momentum. But its a very poor question - see below. _________________________________ For particles with mass, momentum = mass x velocity. Gamma photons have no mass but for technical reason they have momentum - usually this is very small. The mass of an alpha particle (2 protons + 2 neutrons) is about 8000 times the mass of a beta particle (electron). For this reason alpha particles usually have most momentum. But a very fast beta particle could have more momentum than a very slow alpha particle. And a very hight energy gamma photon could have more momentum than a slow beta particle. So the question can't actually be answered definitively.

Sunspots are cooler regions on the service and look black for this reason.
