Reasons for the seasons

The reason we have seasons on our planet is because...

• we are closer to the sun during the winter and further during the winter.

• the tilt of Earth's axis allows for more direct sunlight in the summer and less direct sunlight in the winter.

• seasonal wind patterns carry warmer winds during the summer and colder winds during the winter.

• the Earth's orbit becomes more like an oval to give us different seasons.

As the angle of light decreased (when you started to angle the flashlight closer to the paper) what can be inferred about the temperature?

Which of the following best describes the tilt of the earth during the spring and fall equinoxes?
