1 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.

2 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?

3 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.

4 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

5 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

6 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
