How does the tilt of Earth’s axis affect the seasons?
When your hemisphere is tilted towards the sun, you experience more intense sunlight for longer periods.
When your hemisphere is tilted away from the sun, you experience less intense sunlight for shorter periods.
This causes the seasons.

Mrs. Gibson was driving a boat. Lighthouse lights are very bright. When Mrs. Gibson was far away from land, she could still see the lighthouse, but it appeared small.
How is this similar to the stars in the sky at night time?
The farther Mrs. Gibson got from the lighthouse, the smaller the light got. This is true for the stars too. They are so far away that they seem small. They would seem to get larger the closer we get.
Which tool would we use to collect data about Mars from outer space?
Space probe, satellite, or telescope
Space probe
Which planet has the longest revolution around the sun? Why?
