How The Sun Helps/Harms
Without the Sun, nothing would be able to
live on Earth. It provides us with light and heat
so we don’t freeze to death, and so plants can
grow. The light from the Sun can also be used to
make solar energy.
If in sunlight for too long, you can get
sunburns, and possibly skin cancer or
heatstroke. Heat waves and droughts can also
be caused by the Sun.
Apollo and Helios
 In Ancient Greece, both Apollo and Helios were
thought to be the Sun God.
 The Greeks believed that every day, the Sun god
would drive the Sun Chariot across the sky, which
was what caused Sunrise, daytime, and Sunset
 In one myth, Helios let Phaethon, his son, drive the
Sun Chariot for a day, but Phaethon lost control of the
horses. Zeus, not wanting the chariot to get to close
to Earth and cause damage, hit Phaethon with a
lightning bolt, which killed him.
 The Sun God was thought to be able to see
everything that happens on Earth. In the myth of
Persephone, Demeter, trying to find her daughter,
asked Helios if he knew what happened to her. Helios
was able to tell her that Hades had kidnapped her.
