How is the presence of clouds between the sky and the earth understood, given that they are within the atmosphere, which is considered part of the earth based on the interpretation of the verse, "Say, 'Travel through the land'"?

The clouds are within the atmosphere, positioned between the heaven and the earth, and perceptibly separate from the earth despite their proximity to it. The atmosphere acts as a ceiling for the earth, and the earth floats in space like a ship, with its atmosphere serving as its ceiling. It revolves around the sun at tremendous speed without us feeling it, due to the strength of its gravity and atmospheric pressure.
