AUTUMN
By Jack Walker and Alex Snow.
When it begins
• It begins around the 23 of September.
Why does it get colder
• The earth axis* is tilted by 23.5d. The earth moves round the sun. The suns rays are further away from the earth in autumn.
• *The axis is the line that connects the north pole to the south pole.
Why do fruit ripen in autumn?
• It ripens because it is the end of the sunshine.
Why do the leaves change colour
Because the chlorophyll* goes away.
• *Chlorophyll is what makes leaves green.
Why some leaves are green and some are brown
• The brown leaves are made from the wastes. The red leaves are made from the glucose still trapped in the leaves.
