Apes Ch.5 Flashcards
Coriolis effect
heated air masses rising above the equator and moving north and south to cooler areas are deflected to the west or east over different parts of the planet
Convection cells
convection cells
when hot and wet warm air rises, cools, and releases moisture as precipitation and heat
Rain shadow
low precipitation on the far side of a mountain when prevailing winds flow up and over a high mountain
Windward
side of a mountain range where air rises, cools, and releases moisture
Leeward
side of a mountain range where air descends, warms, and releases little moistur
Monsoon
periods of heavy rain experienced on continents lying north and south of warm oceans
Microclimate
the climate of a small, specific place within an area as contrasted with the climate of the entire area
Biomes
large terrestrial regions characterized by similar climate, soil, plants, and animals, regardless of where they are found in the world. determined by precipitation, temperature and soil type.
Tundra
northern biome that has no trees and is characterized by permafrost
Chaparral
temperate shrub lands. has a moderate climate but its dense thickets of spiny shrubs are subject to periodic fives
Temperate grassland
covers vast expanses of plains and gently rolling hills in the interiors of north and south america, Europe, and asia
Permafrost
underground soil in which water stays frozen for more than 2 consecutive years
without wind
tropics would b hot and everywhere else would freeze
wind
transport nutrients from one place to another.
phosphates/iron blows from sahara desert to across the atlantic. builds soil in bahamas and supplies nutrient for brazil rainforest.
dust/iron from gobi desert to pacific ocean- stimulates growth of phytoplankton.
bad news- wind
dust form sahara have increased bc of drought climate change overgrazing vehicles speeding over sand break desert crust
wind transports viruses, pesticides, toxic metal
reddish soil/pesticides from Afica blows to US, erodes farmland. pollutes air
fungi in this dust degrade coral reefs in florida keys.
red tide
iron rich dust from africa- enhance productivity of algae=algal blooms (red tides) in florida. ppl eat shellfish contaminated by toxin produce in red tide n become paralyzed/ dead
pollution and dust from asia
blow across pacific n degrade air over western US. contribute to smog in west coast
volcanic eruption
particles ride the wind, circle globe n temporary change temperature.
mt pinatubo cooled earth for 3 yrs. ash adds trace minerals to soil
weather
area’s temp, precipitation, humidity, wind speed, clouud cover
conditions of lower atmosphere
climate
region’s general pattern
determined by average temp n precip
related factors: latitude n elevation
Factor contributing to a local climate
Amount of solar radiation, earth rotation n orbit Air circulation Distribution of land n seas Ocean circulation Elevation
Factors determine global air circulation pattern
Uneven heating of the earth’s surface by the sun
Seasonal changes in temp n precipitation
Rotation of earth on axis-coriolis effect
Properties of air, water, land
Prevailing winds
Major surface winds that blow continuously n distribute air, moisture, dust over earth
Properties of air, water, land
Ocean evaporates n transfers heat from the oceans to the atmosphere
convection cells
6, 3 north, 3 south.
warm,wet ar rises n cools n sink
ocean also affects climates
ocean absorbs heat from air exp.: warm tropical areas
warm/cold ocean currents is interrupted by continents so they flow circularly clockwise (north) and counterclockwise (south).
ocean current redistribute heat from sun from one place to another. distribute nutrients n dissolved oxygen
ex of ocean current affect climate. gulf stream
transport more water than all rivers, plays lesser role in climate than air.
greenhouse gas
plays a role in avg temp-climate. absorbs radiation n heats the atmosphere. water vapor is in largest cncentration
land’s effect in climate
heat is released more slowly by water than land. diff creates land n sea breeze.water moderate climate in nearby land
microclimates
created by cities. bricks, concrete, building materials absorb heat n block wind flow.
large amt heat/pollutants. cities have more haze/smog, higher temp, litle wind
