1.    Sunlight is a mixture of ultraviolet, visible, and infrared light.  The incoming sunlight represents energy transport in the form of electromagnetic radiation.

2.    The ground absorbs the incoming sunlight and warms.  Energy is transported by conduction into a thin layer of air in contact with the ground.  It is only a thin layer because air is a poor conductor of energy.

3.    Warm rising air illustrates energy transport by convection (free convection in this case).

4.    Rising air cools.  If the air is moist and is cooled enough (to the dew point temperature) a cloud can form.  Water vapor condenses to form small droplets of water.  This phase change will release latent heat energy into the surrounding air.
