When the sky is blue, does it mean that the sky is actually free of cloud cover, or simply that the cloud is too rarified to be visible?

Well, sometimes there can be clouds very high up that are so thin and spread out that the sky just looks like a lighter blue than it might. However, clouds themselves don't exist all the time... certain conditions, including seeds of some sort (usually dust) on which water can begin condensing. That's one reason you see clouds form behind planes, because their exhaust provides the seeds on which water can condense.

the belief of a threat cloud is extremely imprecise, and an older thought from whilst human beings have been first suffering to understand quantum mechanics. interior the final 2 an prolonged time, experiments with entanglement have reported that debris have not got a different region, and stay related to distant debris. The older double slit test additionally shows this. it would desire to be extra clever and cutting-area to take the view there are possibly no longer such issues as debris, basically wave applications and measurements. wherein case, if one integrates the sq. of the wave function over a community, this provides the threat that an electron would be recent in that section.

well it depends what you call a cloud... but i suppose clouds are always there as the hydrological cycle it always taking place... so id say the cloud is too rarified to be visible

Water vapour is always there.
Cloud is a term used to describe the visible gathering of water vapour. So no, clouds aren't always there. Remember a cloud isn't a substance, it's a name we give to something we can see. Different things there.

At some place at all times there is cloud cover over the earth.

neither. clouds are formed by water droplets in the atmosphere at differing heights, based on temperature and amount of water availble to form a cloud. lower/higher amount of water, fewer or/and thicker clouds.

no not all the time at times the clouds are very clear
