Answer 1

The change in tilt determines at what angle the sun hits certain parts of the Earth. The more direct the sun rays, meaning the sun is higher in the sky shinning straight down, the more effective it becomes at heating the area. The more indirect, meaning that the sun shines at an angle, the less effective.

You can test this yourself with a powerful flashlight using a traditional incandescent bulb. If you hold it directly above your skin shining down, it will feel warm. If you shine it at an angle, you might not feel anything.
