The _________ ________ is the name given the convection current that operates to the immediate north and south of the equator.
The Hadley Cell
NAME THE 3 Global Atmospheric Circulations
- FERREL 60-30
- HADLEY 30-0 (EQUATOR)
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.
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.
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.
Low pressure areas can either be caused by
- 1. solar radiation
- 2. turbulence generated by the rotation of the Earth.
In a general sense, wind is the flow of air from an area of _______ pressure to an area of _______ pressure.
HIGH TO LOW
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
- IT DOES NOT EXIST AT THE EQUATOR.
- MAX AT THE POLES.
THE CORRELIS EFFECT INCREASES WHEN YOU INCREASE THE _________.
THE FASTER THE FLOW OF AIR THE STRONG THE EFFECT.
WHY DOES STORMS AND WATER SPIN?
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.
DEFINE Rain Shadow Effect
The Earth’s surface affects climate.
WHAT IS THE BIOMERE ON THE EQUATOR?
Biomes Based on Elevation OF LAUNCHATIDUE
Similar characteristics can arise in distant biomes through _______ __________.
- ex: cacti in North America and euphorbs in African deserts appear similar
- but are from different evolutionary lineages
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.
- Equatorial and subequatorial
- 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
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
Found on many continents
Precipitation is highly seasonal
Winters are cold (often below –10C) and dry; summers are hot (often near 30C) and dry
Boreal forests, or taiga, represent the largest terrestial biome.
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
- 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
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
3 BASIC LAYERS OF THE OCEAN
- EUPHOTIC 0-200
- BATHYAL 200-1500
- ABYSSAL 1500 - THE BOTTOM
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
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
3 ZONES OF THE WETLANDS
- SOURCE ZONE
- TRANSITION ZONE
- FLOODPLANE ZONE
NAME A TYPE OF COASTAL WETLAND AND WHY IT IS IMPORTANT
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
