answer the question.
At high latitudes, one might look into the night sky and see dazzling curtains of colorful
light. This brilliant sight, known as an aurora, is the result of solar winds. Solar winds
occur when the outer layers of the sun boil off due to the intense heat, emitting streams
of magnetically charged particles into the surrounding space.
Some of these solar wind particles end up traveling in Earth's direction. If unimpeded,
these partides would have deleterious effects on human health, increasing the risk of
heart failure and other health problems. But Earth's magnetic poles-located near the
geographic North and South Poles-create a magnetic field that protects the planet from
the solar wind partides. Some of these particles, however, do manage to break free and
end up colliding with oxygen and nitrogen in Earth's atmosphere. The collisions release
energy, thus creating the aurora's stunning display.
