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...

how conduction leads to convections at earth's surface
how convection leads to conduction at earth's surface

how thermal energy is transferred from substances on Earth's surface to the surrounding air

which of those 2 possible answers!!!

Oh, I apologize for the confusion. The correct answer is:

how conduction leads to convection at Earth's surface.
