A park-like landscape of grasslands with scattered trees that can survive dry spells. Vegetation depends on elevation, since temperatures drop as altitude increases. Vast grasslands cover regions that get more rain than deserts but too little to support forests Materials or substances such as minerals, forests, water, and fertile land that occur in nature and can be used for economic gain Steady hot temperatures and moist air support the rich ecosystems known as tropical rain forests group of plants and animals that depend on each other and their environment for survival coniferous trees are trees that produce cones to carry seeds. They also have needles. These features protect trees through the cold, dry winters of subarctic climates. dry semiarid areas and deserts with some rain support animals and low-lying desert plants. Shrubs and other low plants in Mediterranean climates have to hold water from winter rains to survive hot, dry summers a covering of ice over a large area, especially on the polar region of a planet. Moist temperate climates support thick forests of deciduous trees
