1 Climate and Terrestrial Biodiversity
G. Tyler Miller’s Living in the Environment 14th Edition Chapter 6

2 Key Concepts Factors influencing weather Factors influencing climate
Effect of climate on distribution of biomes Characteristics of major biome types

3 Weather: A Brief Introduction
Warm front Cold front Jet Streams Weather extremes Fig. 6-2 p. 102

4 Atmospheric Pressure High Pressure, Low Pressure

5 Climate Temperature Precipitation Fig. 6-5 p. 105

6 What Determines the different climates that occur?
The Amount of Incoming Solar Radiation (Insolation) per unit of land Air Circulation Water Circulation Fig. 6-5 p. 105

7 Factors Influencing Air Patterns
Uneven heating of earth’s surface Earth’s Tilt and resulting seasons Earths Rotation Properties of air water, and land Fig. 6-5 p. 105

23 Figure 6-16 Page 111 Tropic of Cancer Equator Tropic of Capricorn
Semidesert, arid grassland Arctic tundra (polar grasslands) Desert Boreal forest (taiga), evergreen coniferous forest (e.g., montane coniferous forest) Tropical rain forest, tropical evergreen forest Mountains (complex zonation) Temperate deciduous forest Tropical deciduous forest Ice Temperate grassland Tropical scrub forest Dry woodlands and shrublands (chaparral) Tropical savanna, thorn forest

24 Biomes: Climate and Life on Land
Relationship between latitude and altitude Desert Biomes Grassland, Tundra and Chaparral Biomes Forest Biomes Mountain Biomes

25 Biomes: Latitude and Altitude
Refer to Fig p. 112 Fig p. 112

26 Desert Biomes Tropical deserts Temperate deserts Cold deserts
Refer to Fig p. 114

27 Grassland, Tundra, and Chaparral Biomes
Tropical grasslands and Savannas Temperate grasslands Polar grasslands (Arctic tundra) Permafrost Alpine tundra Chaparral Refer to Figs. 6-23, 6-24, and 6-25 pp

28 Forest Biomes Tropical rainforest Temperate deciduous forest
Evergreen coniferous forest (boreal forest) Temperate rain forest Refer to Figs. 6-29, 6-30, 6-31, and 6-32 pp

29 Mountain Biomes Mimic latitude Islands of biodiversity
