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.
What Kind of Soil Do Aloe Vera Plants Need? Aloe vera is grown both for its medicinal properties and as an ornamental. Aloe vera plants (Aloe vera or Aloe barbadensis) are originally native to arid parts of northern Africa. They do best in warm, sandy environments and must be grown indoors in much of the United States.
