Substances on Earth's surface absorb light energy from the sun. This
energy causes particles to move, which leads to increases in their thermal
energy, then increases in their temperature. Warmed substances on Earth's
surface transfer thermal energy to air molecules that collide with the
surface by conduction. These rising warm air molecules then create a
convection current in the air. This explains...
