Transcript of What is the relationship between climate and the types of vegetation throughout the world?
• What is the relationship between climate and the types of vegetation throughout the world?
What are the major patterns of vegetation found on
Earth?
Are similar vegetation patterns found in different parts of the
world?
What animals are associated with the different vegetation
patterns?
What type of adaptations are selected for in different biomes?
Do climates change over time?
What influences the climate of a particular region?
What influences the climate of a particular region?
1. Altitude - altitude, temperature2. Latitude – sun’s radiation is less direct as
you move N or S from equator Proximity to large body of water (moderates
temperature)Proximity to mountainsAlbedo (albedo = reflection = temperatureHumidity
Temperature and Precipitation Patterns
Humidity: Amount of water vapour in air (reported as % water that air can hold at a specific temperature).
Humidity as temperature Humidex = combines temperature and precipitation to give an indication of what the air “feels like” to people
HUMIDEX CHART
Temperature and Precipitation Patterns
When air cools, thermal energy is removed from water vapor in the air, changes from gas to liquid (Hvap)
The temperature when water vapor in air condenses is called DEW POINT.
PrecipitationRain (mm), snow (cm) 1 cm snow = 10 mm
rain
Biomes
Major geographic regions with similar environmental conditions
Examples????
Taiga (boreal), desert, tropical rainforest, grasslands, fresh water, oceans, temperate deciduous, tundra…..
EcosystemA community of living organisms
that interact with each other and with the non-living (abiotic), physical environment.
Examples?
HabitatWhere an animal or plant lives (home)
Examples?
Match animal to its habitat
Adaptations3 types
1) physiological – occurs inside organism
Examples?
Cold blooded vs. warm blooded
Cold-blooded vs. warm- bloodedGizzard in bird, 4 stomachs in cows
(digestion)Venom (snakes)
Blue-ringed octopus
Poison dart frog
Black widow spider
2. Structural Adaptations
Physical features on outside
Examples?
Claws, teeth, camouflage, spines and thorns on cactus and plants
3. Behavioral Adaptations
What an organism does
Examples?
Migration, hibernation, nocturnal behaviors, mating behaviors and dances, broken wing behavior in birds
