Clouds float because condensed moisture, descending by gravity, meets warmer temperatures rising from the land. That moisture then changes into vapor and ascends back into the air.
But natural explanations are not the final answers.
Clouds float because God in His wisdom reveal “the wondrous works of Him who is perfect in knowledge” (Job 37:16).
God makes the clouds float through the air.
He does so to call us to wonder and adoration.
