In an average year the climate in a tropical rain forest is very humid because of all the rainfall. A tropical rainforest gets about 150 cm of rain per year. It gets lots of rain because it is very hot and wet in rain forests. The hotter the air, the more water vapor it can hold.
Across America, the Russet Burbank has a declining market share, but is still no small potatoes. In 2008, Idaho potato farmers planted 57 percent of their total acres with Russet Burbanks, while the variety accounted for 41 percent across the eight biggest potato-producing states.
Where does the potato come from ? The potato (Solanum tuberosum) of the family Solanaceae (nightshade family) is one of the most widely used vegetables in Western temperate climates. The plant is probably native to the Andes, where it was cultivated by the Incas.
