The flashcards below were created by user shockwave on FreezingBlue Flashcards. What would you like to do?


  1. The _________ ________ is the name given the convection current that operates to the immediate north and south of the equator.
    The Hadley Cell
  2. NAME THE 3 Global Atmospheric Circulations
    • POLAR 
    • FERREL 60-30
    • HADLEY 30-0 (EQUATOR)

  3. The Ferrel Cell is generally considered to be the weakest of the cells.
    • The Ferrel Cell.
    • While the classical conception of the cell has it acting as a ‘ball bearing’ between the Hadley Cell and the Polar Cell, some studies have shown it to be much smaller in intensity.

  4. The _____ _____  themselves are centres of _________ pressure where air descends.
    The poles cells themselves are centres of high pressure where air descends.

    • This means that there is little heat transfer from lower latitudes towards the poles and therefore the majority of the energy received is from the sun.
    • Trade winds in Polar Regions are the same as those close to the tropics; they are easterlies due to Coriolis force.
  5. T OR F 
    Global atmospheric circulation is largely due to unequal surface heating and the resulting convection cells have a major impact on regional climates.
    TRUE
  6. Low pressure areas can either be caused by
    2 THINGS
    • 1. solar radiation
    • 2. turbulence generated by the rotation of the Earth.
  7. In a general sense, wind is the flow of air from an area of _______ pressure to an area of  _______ pressure.
    HIGH TO LOW
  8. The observed effect of the Coriolis force, especially the deflection of an object moving above the earth, _________ in the northern hemisphere and _________ in the southern hemisphere.
    • rightward in the northern  
    • leftward in the southern 

    • FYI
    • IT DOES NOT EXIST AT THE EQUATOR. 
    • MAX AT THE POLES.
  9. THE CORRELIS EFFECT INCREASES WHEN YOU INCREASE THE _________.
    SPEED. 

    THE FASTER THE FLOW OF AIR THE STRONG THE EFFECT. 

  10. WHY DOES STORMS AND WATER SPIN?
  11. WHY DO HURICANES HAVE "EYES"
    THE CENTER IS A LOW PRESSURE SYSTEM, BUT THE CORRELIS EFFECT MAINTAINS IT BY DEFLECTING THE WINDS. COUNTERCLOCKWISE IN THE NORTH. CLOCKWISE IN THE SOUTH.

  12. DEFINE Rain Shadow Effect
    —The Earth’s surface affects climate.

  13. WHAT IS THE BIOMERE ON THE EQUATOR?
    TROPICAL FORREST.

  14. Biomes Based on Elevation OF LAUNCHATIDUE
  15. —Similar characteristics can arise in distant biomes through _______ __________.
    —
    Convergent Evolution

    • ex: cacti in North America and euphorbs in African deserts appear similar
    • but are from different evolutionary lineages
  16. Temperate Rain Forest IN THE USA
    RED WOOD FOREST OF THE WEST COAST.

    • —Found in scattered coastal temperate areas that have ample rainfall or moisture from
    • dense ocean fogs.
  17. DEFINE SAVANNAH
    • —Equatorial and subequatorial
    • regions

    • —Warm temperatures year round with
    • wet and dry seasons

    —Precipitation is seasonal

    —Temperature averages (24–29°C) but is more seasonally variable than in the tropics

  18. Chaparral
    —Occurs in mid-latitude coastal regions on several continents

    —Summer is hot (30°C+); fall, winter, and spring are cool (10–12°C)

    • —Close to sea provides a slightly longer winter rainy season than nearby temperate
    • deserts.

  19. Temperate Grasslands
    Found on many continents

    Precipitation is highly seasonal

    Winters are cold (often below –10C) and dry; summers are hot (often near 30C) and dry

  20. LARGEST BIOMERE
    Boreal forests, or taiga, represent the largest terrestial biome.

  21. Deciduous VS Coniferous WHATS THE DIFFERENCE?
    • Deciduous = TRESS WITH LEAVES 
    • 750 to 1,500 mm of rain per year

    • Coniferous = EVERGREEN COLDER CLIMATE
    • 300 to 900 millimeters of rain per year
  22. TUNDRA
    • —Covers expansive areas of the
    • Arctic; alpine tundra exists on high mountaintops at all latitudes

    • —Precipitation is low in arctic
    • tundra and higher in alpine tundra
  23. how are aquatic biomes classififed?
    • Pelagic  (EUPHOTIC) Zone: (2 parts):
    • Photic Zone has sufficient light for photosynthesis; most animals live here

    • —Aphotic Zone receives little light; extensive
    • with little life 
    • Abyssal Zone  (LOWER PART OF APHOTIC)
    • with a depth of 2,000 to 6,000 m

    —Benthic Zone

    —Detritus
  24. 3 BASIC LAYERS OF THE OCEAN
    • EUPHOTIC 0-200
    • BATHYAL 200-1500
    • ABYSSAL 1500 - THE BOTTOM

  25. —Oligotrophic Lakes
    Nutrient-poor and generally oxygen-rich

    Small supply of plant nutrients

    Generally deep with steep banks; fed by glaciers and mountain streams with little sediment; crystal clear
  26. —Eutrophic Lakes
    —Nutrient-rich and often depleted of oxygen if ice covered in winter

    —Rooted and floating aquatic plants live in shallow and well-lighted  area close to shore

    —Water is too deep  to support rooted aquatic plants; small drifting animals called zooplankton grazeon the phytoplankton

    —Invertebrates live in the benthic zone; Fishes live in all zones with sufficient oxygen
  27. 3 ZONES OF THE WETLANDS
    • SOURCE ZONE 
    • TRANSITION ZONE 
    • FLOODPLANE ZONE 

  28. NAME A TYPE OF COASTAL WETLAND AND WHY IT IS IMPORTANT
    MANGROVE FORREST. 

    Found along 70% of gently sloping sandy and silt coastlines in the tropics and sub-tropics.

    • —Maintain water quality by filtering toxic pollutants, excess plant nutrients, sediments
    • and absorb other pollutants

    —Provide food, habitats and nursery sites

    • —Reduce storm damage and coast erosion by absorbing waves and storing excess water
    • produced by storms and tsunamis
  29. deciduous TREES
    HARDWOOD. THINK LEAVES. 
  30. HERE IS A MAP OF THE TEMPERATURES AND RAIN FOR DIFFERENT BIOMES. 

    FREE NO QUESTION, JUST A PRETTY GRAPH.
  31. 3 CLOUD LAYERS
    • CIRRO HIGH
    • ALTO MIDDLE 
    • STRATO LOW 

    CUMMULONIMBUS THINDER STORMS
