How Climate Affects Vegetation Unit 2, Section 4
Climate and Vegetation • Each climate has its own type of natural vegetation because different plants require different amounts of water, sunlight and temperatures to survive. • There are 5 broad types of climate: Tropical, Dry, Temperate Marine, Temperate Continental, and Polar. A huge western red cedar needs lots of water but can survive in cooler climates. A cactus needs little water but warm temperatures to survive.
Earth’s Climate Regions • Tropical Climates: 2 main types, both are hot. One type has rain all year, the other has wet and dry seasons. • Dry Climates: 2 main types, arid (dry) and semiarid (semidry). Hot summers and mild winters. • Temperate Continental Climates: 2 main types, humid and subarctic. Humid has moderate to hot summers but cold winters. Subarctic is drier with cool summers and cold winters. • Temperate Marine Climates: 3 main types all have mild winters. Marine west coast and humid subtropical are very wet, mediterranean is drier. • Polar Climates: 2 main types, both are cold all year round. Tundra have short cool summers, ice caps are bitterly cold all year.
Earth’s Vegetation Regions • Tropical Rainforest: lots of sunlight, heat and rain allow for thousands of different species of plants. The uppermost layer of branches is called the canopy. • Tropical Savanna: grassland areas with scattered trees found in areas with dry seasons.
Desert: little or no vegetation at all. Scattered plants absorb scarce water before it evaporates. • Desert Scrub: low desert vegetation that needs little water. Some plants flower only when it rains so seeds have a better chance to survive. • Mediterranean Vegetation: grasses, shrubs, low trees. Must hold moisture rainy season to survive the dry season.
Temperate Grasslands: mix of tall grasses and other plants that is sometimes called prairie. • Deciduous Forest: trees that loose their leaves in the fall. • Coniferous and Mixed Forest: Coniferous trees produce cones and generally have needles to help trees in drier climates.
Tundra: mosses, grasses, and low shrubs that bloom during brief, cool summers. • Highland: vegetation depends on the elevation, since temperatures drop as elevation rises. • Ice Cap and Pack Ice: No vegetation grows here.
