The Strange Northern Lights If you find yourself in (1)
Norway or other northern places at
night, you might be lucky enough to see
the aurora borealis, or northern lights.
Seeing (2)
lights is an amazing
experience. Sometimes they look like
(3) _ band of green colour
across (4)
sky, and at other
times they look like (5)
curtains of purple, red and green.
What causes them? Energy from
(6)
sun stirs up atoms high
up in (7)
atmosphere. The
Earth is like (8)
large magnet
and it traps (9)
atoms. These
atoms then release their energy, and this
produces light, Exactly (10)
same thing happens in the far south,
where (11)
lights are known
as (12)
aurora australis.​
