GEO 206 Exam 2 with complete solutions

Af Tropical rainforest climate Narrow temperature range because of high sun angle. High precipitation rates due to influence of ITCZ Dense rainforest vegetation Am Tropical monsoon climate Distinct wet and dry season related to air flow in the low latitudes. Located on the eastern side of landmasses where trade winds bring humid air seasonally and also SE Asia and SW India Rainforest vegetation. 0:49 / 0:54 6 Ways to Show Appreciation for Your Child's Teacher Aw Tropical savanna climate Located poleward of Af Has distinct wet and dry seasons related to dominance of ITCZ and STH Vegetation is mix of grass and trees called savanna BWk Cold midlatitude desert climate In the Gobi Desert (china), smallest climate group Dry because of cold ocean currents, low rainfall levels Typical desert vegetation BWh Hot low-latitude desert climate Found in the center and eastern sides of STH (15 to 30 latitude in SH and NH) Hot because of little clouds and high sun angle, very little rainfall Vegetation is sparse Cfb Marine west-coast climates Located on the west coast of continents (btwn 35 to 60 latitude N and S) Wider temperature range that's cooler, receive a lot of rainfall Vegetation is needle-leaf trees Dfa Humid continental hot-summer climates Located in central and eastern parts of NA and Eurasia Moist with a lot of rainfall each month. temperature ranges from warm summers to cold winters Influenced by the midlatitude jet stream Tropical Rainforest Biome Located in the equatorial region Associated with small with Af zone and small areas of Am - limited dry season. Wide array of vegetation, trees experience no seasonal leaf fall because of the constant high temps and moisture (evergreen) Consists of four vertical layers: emergent layer, canopy, understory, and the ground layer Tropical Deciduous Forest Biome In Africa, South America, India and SE Asia. Dry tropical areas with distinct dry seasons in Am and Aw Temperature varies but is always above 64F Wet areas dominated by deciduous forest, the trees drop their leaves in the dry season Less species diversity than the rainforest but has a great array of shrub species and smaller ground level plants Tropical scrub in areas with lower rainfall Midlatitude Coniferous Forest Biome West coast and mountains of NA, SE united states, and eastern Europe Needle-leaf evergreen trees Humid continental mild-summer climate with short growing seasons occurring at low latitudes and high elevations where temperature is cool - "temperate rainforest" SE coniferous forest is hot and humid, high biodiversity Hot and Dry Desert Biome Located in the subtropical region, centered on 30 latitude associated with BWh Mojave, Kalahari, Sahara and Sonoran deserts are in this biome Low annual precipitation and high average temperature, moisture deficit Vegetation is xerophytic plants (cacti, shrubs, scattered grass) that are drought resistant...also drought evading plants Semi-Arid and Cold Desert Biome Western NA and central Asia associated with BWk Distinct seasonal temperature patterns with hot, dry summers and cold winters Vegetation is sparse plants that have glossy leaves that give them a higher albedo helping to reflect radiation Alfisols Form by podzolization (occurs in cool, humid environments resulting in elevation of iron, aluminum and organic acids) which create a well-developed E and B horizon Have a distinct O horizon and A horizon Occur in warmer regions where the litter consists of deciduous leaves Distinct light E horizon Ultisols Form in warm, moist, subtropic
