  1. The Sun becomes hotter
  2. Earth stops radiating heat
  3. Light is concentrated over less area ✔

Why: A high Sun angle spreads the same incoming beam over a smaller surface area. Summer also provides more daylight time, so heating continues longer each day.

Huh, didn't know that: A low winter Sun spreads the same sunlight over a larger patch of ground, so each square meter gets less energy.
