1. Due to the difference in temperatures, the Sun emits mostly visible radiation and the Earth emits mostly infrared radiation.
   
   
2. When water substance freezes and condenses, latent heat is released. This causes the temperature of the environment to go up.
   
   
3. The fact that the Earth is spherical is the main reason why the Sun heats the tropical regions more than the polar regions, which requires a poleward heat transport by the atmosphere and oceans.
   
   
4. The fact that the Earth is tilted is why the daily insolation changes throughout the year for any location on Earth (except the Equator).
