10.3 The Sun-Earth Connection
Solar Activity Solar weather include sunspots, solar flares and solar
All solar activities are related to magnetic fields: electric currents in the
Sun act like magnets, pushing on charged particles.
Sunspots Regions with strong magnetic fields
Sunspots are regions kept cooler than other parts of the Sun’s surface by
strong magnetic fields.
Magnetic Field Lines Drawing lines represent the directions in which compass
needles would point
Lines closer together indicates a stronger magnetic field.
Charged particles spiral along magnetic field lines.
Solar Prominences Loops of bright gas connect sunspot pairs
Loops connecting sunspots trace magnetic field
