What causes thunderstorms? Thunderstorms form when an air mass becomes so unstable that it overturns (convects) violently. Unstable means that the air in the lowest layers is unusually warm and humid, or that the upper layers are unusually cool, or oftentimes, both.
Aloe is the name of a plant genus that contains more than 300 species. Most of the aloe species are native to Africa, Madagascar and the Arabian Peninsula. In addition to the familiar cactus-like plant called aloe vera that many people use to soothe sunburns and other skin ailments, this genus has plants that range from grassy succulents to large trees.
The most commonly known aloes is aloe vera (Aloe barbadensis). Although hardy in U.S. Department of Agriculture plant hardiness zones 10 through 12, it is normally grown indoors. As a houseplant, it thrives in well-drained potting soil, tolerates some shade, but does best in full sun.
