Section 3: Climate and Vegetation Patterns Big Idea: All the world’s climates support a variety of ecosystems. Write the bold vocab words and definition. Get out another piece of paper and title it 3.3 notes.
Read to Discover How do the two tropical climates differ? What conditions are common in dry climates? What climates are found in the middle latitudes? What characterizes high-latitude and highland climates?
Tropical Humid Climate Close to equator Warm temperatures Rainfall all year Receives Sun’s rays directly all year Rising warm air Rain forests Monsoons Tropical Wet and Dry Climates North &south of tropical humid Caused by seasonal change in this area Alternating wet &dry seasons Savannas Tropical Climates Ecosystems- community of plants, animals and non-living things in an area. Vary around the world.
Arid climate (desert)-dry, low rainfall – Generally centered about 30 degrees north & south of equator – Subtropical high-pressure zone causes sinking dry air, with little rain. – Winters may be very cold, summers very hot. – Hardy plants & animals Semiarid climate- btw humid & arid areas/ more moisture than the Arid climate. Dry Climate Areas-Arid & Semiarid
Middle latitudes – found between the tropical and the high polar regions. Mediterranean—Long, dry summers & mild winters; scrub woodland vegetation Humid Subtropical—Hot, humid summers & mild winters; temperate forests Marine West Coast—Mild all year; may support dense forests Humid Continental—Variable, with four seasons; enough rain to support forests Middle-Latitude Climates
Subarctic—Long, cold winters and short, warm summers; vast evergreen forests Tundra—Long winters, with permafrost; low shrubs, lichens, mosses, ferns Ice Cap—Polar climates; few land plants or animals Highland—Varies by elevation, with low elevations relatively mild & high elevations similar to ice cap High-Latitude and Highland Climates
