According to the author, what is the one feature all deserts have in common? A) large quantities of oil just below the surface B less than 10 inches of precipitation per year (C) cycles of extreme drought and monsoons (D) gradual slopes and very steep valleys

Regardless of their location or climate, all deserts share the hallmark of receiving less than 10 inches of precipitation annually. This defining characteristic leads to the sparse vegetation and arid conditions that we often associate with these vast landscapes, making them unique ecosystems.

For example, communities in deserts often rely on innovative water conservation techniques to thrive in such conditions!
