Which type of cloud is described as being in the form of patches and not close to the ground?

The type of cloud described as being in the form of patches and not close to the ground is known as cirrus clouds. Cirrus clouds are high-altitude clouds that appear wispy and thin, often resembling strands of hair or feathery plumes. They are composed of ice crystals and typically signify fair weather, although they can also indicate that a change in the weather may be on the way.

Unlike the other cloud types, cirrus clouds are not dense or low-lying, which distinguishes them from cumulus, nimbus, and stratus clouds. Cumulus clouds are typically fluffy and can form in cotton-like clumps, often associated with good weather or convection. Nimbus clouds are characterized by their rain-bearing capability and are typically thick and dark. Stratus clouds are low-level clouds that often cover the sky in uniform layers and can bring overcast conditions.

The characteristics of cirrus clouds make them unique from these other types, which is why they fit the description provided in the question.
