5 Desert General Geographic region: Typically near 30oN and 30oS latitudeNear interior of continents30% of Earths surfaceClimate information:Evaporation exceeds precipitationTropical desert: hot and dry year roundTemperate desert: cooler in winter; more vegetation; more precipitation than tropicalCold desert: cold winters/hot summers
6 DesertGeneral fauna:Lizards, snakes, kangaroo rat, roadrunner, jack rabbitMost animals are small, active during cool parts of day and night, wastes contain little waterGeneral flora:Cactus, yucca, agave3 adaptations: no leaves, store water, open stomata only at night.Lifecycles: bloom, seed, and die quickly
7 Desert Environmental concerns: Deserts are expanding (desertification) Storage of toxic wastesTesting for nuclear weaponsPictures:
8 Grasslands General Geographic region: Continent interiors Climate information:Enough precipitation to support grasses and shrubs, but fewer treesCan be tropical, temperate, or polar
9 Grasslands General fauna: Hoofed herbivores, grazing animals Giraffe, elephant, warthog, gazelle, tigerGeneral flora:Mostly grasses with deep roots, fewer trees that are drought tolerantPlants must be able to re-grow after frequent fires
15 Deciduous Forest General Geographic region: Further from equator Between 30o and 60o N and S latitudeClimate information:Significant change in temperatures during seasons.Precipitation fairly evenly spread over year.Warm summers, cold winters
16 Deciduous Forest General fauna: Many top predators have been extirpated (wolves, cougars, bear)Deer, raccoons, squirrel, (our area animals)General flora:Trees drop leaves in winterFewer tree species than TRForests, but more ground level plant life
17 Deciduous Forest Environmental concerns: Loss of biodiversity Large predators removedDeforestizationPictures:
18 Taiga (Boreal Forest) General Geographic region: Found in the north Just south of the arctic tundraClimate information:Winters are long, dry, and very cold.Winter sunlight is 6-8 hours a day.Mild summers with 19 hours of sunlight a day.
19 Taiga (Boreal Forest) General fauna: Moose, wolves, rabbits, bear, eaglesGeneral flora:Coniferous trees, some wildflowers and grasses
21 Mountains General Geographic region: Frequently on continent edges; where tectonic plates collide25% of Earth’s surfaceClimate information:Varies depending on elevation.Higher elevation = colderLeeward side of mountains gets less precipitation
22 Mountains General fauna: Big horn sheep, mountain goats, taiga animals at lower elevationsGeneral flora:Little flora at high elevation, lichen, conifers as you go down in elevation
