The document describes several different climates around the world. It discusses tropical rainforest climates, which are characterized by dense plant growth and heavy rainfall. Savanna climates have a wet and dry season, with warm temperatures and almost no rainfall during the dry season. Tropical deserts have extreme lack of moisture due to trade winds being unable to bring in moisture from the sea. Steppe climates have slightly more moisture than deserts and support low grasses and shrubs. Polar climates have little precipitation and slanting sunlight that provides little heat. Tundra climates consist of mosses and small shrubs, with precipitation occurring mostly during short summers. Icecap climates are found near the poles
