No, there is not a thick layer of hummus in dry deserts. Hummus is a food product made from cooked, mashed chickpeas, tahini, olive oil, lemon juice, and other ingredients. It is not naturally occurring in deserts. Instead, dry deserts usually consist of sandy or rocky terrain with minimal organic matter. The term "humus," on the other hand, refers to the rich, organic component of soil formed by the decomposition of plant and animal matter over time.
