Days are longer in the summer than in the winter because:
What is earth's axis is tilted more toward the sun?

What is a low pressure area?
The part of the airplane that causes it to descend.
What are the elevators?
Decaying trees will do this.
What is add nutrients to the soil?
Using a ball to represent the moon, and yourself to represent Earth, you hold the ball straight out in front of you between you and a light source. The phase of the moon you would be representing.
What is a new moon?
Opening the top flap on a hot air balloon allows the balloon to do this.
