Climate and weather
Climatic conditions
How much of the earth do people occupy
Factors that influence climate
Factors that influence climate
Latitude of a place
Factors affecting climate. Latitude or distance from the equator. Temperatures drop the further an area is from the equator due to the curvature of the earth. In areas closer to the poles, sunlight has a larger area of atmosphere to pass through and the sun is at a lower angle in the sky.
reason for higher downpour at equator
factors that influence climate
Altitude above sea level
Altitude or height above sea level
Locations at a higher altitude have colder temperatures. Temperature usually decreases by 1°C for every 100 metres in altitude.
factors that influence climate
influence of ocean currents/oceans

climate
we look at temperature and rainfall
hot, mild, cold climates
hemispheres and climate
wet and dry areas
vegetation - 5 main biomes
interaction between plants, animals, soil and climate within a demarcated area
develops into an ecological system = ecosystem -a election of plants and animals in their own environment
fauna
flora
which biome covers the largest area
which biome covers the smallest area
tropical rainforests = tropical,deciduous,coniferous
dominated by large tree species
dense canopy
grow so close that sunlight doesn't penetrate ground
temperate rain forests= deciduous forests
lungs of our planet = tropical rain forests
most of worlds rain forests occur along the equator
biggest rain forests occur in central and south America, central and west Africa and south east Asia
world's areas with high annual rainfall are same as location of world's tropical rain forests
effect of densely populated areas on natural forests
forest biomes = 3 types
Coniferous
Deciduous
Rain
Coniferous biome
rain forest biome
tropical forest
effects of deforestation = the clearing of forest land
for example by logging= cutting down of trees to use their wood
also from mining, farming, road building
why are tropical rain forests so important?
Coniferous forests
short summers
long cold winters
up sides of mountains
tall narrow trees
shrubs and herbs grow close to ground
half frozen forests
animals hibernate, migrate or store food for winter
trees have cones instead of flowers
needle like leaves protects against cold climate
needles grow downwards snow slides off
Coniferous forests
coniferous forests
how do the following survive cold climate:
coniferous tree
spruce tree
great grey owl
moose
coniferous forests:
why are there few farms in coniferous forest areas
what two things would people do to earn money
why are these dangerous for the environment
deforestation
what is the worst effect? explain your answer
from the list place each plant/animal into a specific biome and say how it is suited to that climate:
Liana vines
Macaw parrot
Camel
Barrel Cactus
Moose
Spruce trees
Macaw parrot
Camel
moose
migrate
hot desert biome
area of land where very little rain falls and where temperatures are high
hot deserts:
Sahara - North Africa
Kalahari - Southern Africa
Australian - Australia
Mojave - North America
Arabian - Middle East
That - India and Pakistan
Atacama - South America
Climate
temperatures usually between 20-25 degrees celcius
can be as high as 50 degrees
nights can be very cold
hot deserts have little or no rainfall for many months
natural vegetation in hot desert
wildlife in hot desert
plants in semi deserts and deserts
semi desert / desert climate
people living in deserts = nomadic = move from place to place in search of water and grazing for animals
oasis
discuss how if you are living in a hot desert you get:
water
food
shelter
Savannah Biome - tropical grasslands
transitional region between wet tropical rain forests and dry desert/semi desert regions
Savannah Grasslands
Savannah grasslands
temperate grasslands = grasslands biome
temperate grasslands
vegetation
temperate grasslands
tundra and ice fields biome
tundra and ice fields biome
tundra and ice fields biome
Ice deserts/ polar deserts
answer the following:
has one season throughout the year
word for vegetation
layer above the understory
not suitable for farming
grassland found in South Africa
answer the following:
10m long roots
hooved animals
tropical grassland
desert vegetation
clearing of forest land
19% of land surface
uninhabitable
what people trade
raw materials
manufactured goods
primary products =
name the two raw materials pictured
name places in SA where these are mined
suggest uses for these raw materials
imports
exports
trade
South Africa and trade
SA exports and imports
SA trades with North America, Asia- China, most countries in Europe and the middle east
factories
secondary products
skills
manufactured goods
skills and services
fair trade vs unfair trade -
when poor countries get low prices for their raw materials this causes other problems
when trade is fair people are able to earn enough money to live and improve their lives
exploitation
examples of exploitation are
Answer the following:
Trade takes place when people ________ goods
Exports leave a country, __________enter a country
____________ are resources that have not yet changed
People use ____________ to make manufactured goods
two important South african primary products are ___________
people who do not make things provide ________, such as nurses and teachers
poor countries sell their exports at ______ and buy their imports at high prices
name two countries that are important trading partners of South Africa
National symbols
symbol=a picture or item that stands for something else or that has a special meaning
motto = phrase or sentence describing what an organisation or country aims for or believes in
MOTTO
IKE E: /XARRA //KE
