what puffy clouds that can be found at middle altitudes
Cumulus clouds are layered but puffy clouds that occur at middle and lower elevations. They are typically associated with fair weather, but can develop into larger storm clouds if conditions become more unstable.
Higher elevations are colder than lower elevations because the air pressure decreases with altitude, causing the air to expand and cool. This results in lower temperatures at higher elevations.
No, it is greater at the lower elevations.
Stratus
Mountains are colder than lower elevations because as altitude increases, the air pressure decreases, causing the air to expand and cool. This results in lower temperatures in mountainous regions compared to lower elevations.
Lower elevations have denser air than higher elevations because air molecules are squeezed closer together by the weight of the air above, creating higher air pressure. This higher pressure at lower elevations results in denser air that contains more molecules per unit volume compared to the lower pressure and thinner air found at higher elevations.
a lower 'height' than whatever its referring to.
The air is thinner than air in lower elevations.
At higher elevations the boiling point is lower.
The thin, wispy clouds you saw are Cirrus clouds and they are very high in the atmosphere and made of ice crystals. They normally indicate a change in the weather, and it is usually bad weather. This means that the low layered cloud you saw was either a stratus or cumulonimbus cloud which are both storm clouds. Cirrus clouds don't always predict storms, but that was probably what was happening.
No
Stratus Clouds form a layer or 'sheet' across the sky and tend to be much lower in the atmosphere
