Answer to Question 1

The Sun's differential rotation wraps its magnetic field lines around the equator as it turns. The north-south orientation of the field lines becomes oriented east-west. Convection further mixes the field pattern, until the field lines are tangled and kinked like a garden hose. Occasionally, the field lines burst out of the surface, forming a sunspot pair in the east-west direction.
