-Why are they light?

Answer 1

- During spring

   -They get plenty of water

Answer 2

The dark bands are formed in the driest time of the year. They are dark because there are more rings closer together which makes them appear dark. When there is lots of water in the whatever climate you live, the trees grow quickly and have a larger whiter band because each layer is wider and appears lighter.
