The Northern Lights

People who live north of the equator might be lucky enough to see the Northern Lights. These natural ‘lights’, which appear in some northern areas of (1) the Earth, often appear as wide green or red lines across the sky. But how (2) are they created?

When tiny particles escape from the Sun and meet solar winds, a (3) number of these particles mix with gases which surround the Earth. This produces an interesting light show in the sky.

You are more likely to see the Northern Lights (4) if you live in a northern country like Iceland or Canada. However, during times of increased solar activity, (5) it is sometimes possible to see the lights in countries further south, though the colours may not be (6) as bright as they usually are.
