weather |
an area's temperature,precipitation,humidity, wind speed, cloud cover, and other physical conditions |
|
Definition of climate and 4 factors that affect it |
region's general pattern of weather conditions over a long time (years,decades,centuries) 4 main factors- Temperature & Precipitation, Latitude & Elevation |
|
What are the four factors of global air circulation? |
Uneven heating,temperature & precipitation, rotation of the earth, prop. of air, water, and land |
|
Wind |
provides nutrients transports pollen, drives ocean currents, controls temperature |
|
High pressure & Low pressure |
High=Good,sunny weather Low= Rainy |
|
Global warming |
Global warming is needed for life, but humans have accelerated it. Without it, it would be too cold. |
|
biomes |
regions characterized by climate,soil,plants,and animals |
|
Tropical Rainforest |
hot,humid,a lot of rain,broadleaf evergreen plants,trees w/ shallow roots & bases,ground level=little vegetation,vines |
|
Taiga |
coniferous evergreen trees,plant diversity is low,low amounts of rain,very cold,cold winters,wet summers |
|
Arctic Tundra |
little rain,very cold,low growing plants,tall plants lose too much heat,permafrost |
|
Grassland |
seasonal drought, grazing herbivores, occasional fires,low average rain, average temperatures,enough rain to support grass but not trees |
|
Desert |
rain is low,little vegetation,during day=hot,during night=cold,plants & animals store water,beat the heat & every drop of water counts |
|
Chaparral |
moderate climate,periodic fires,average precipitation,thin/not very fertile soil,dense low growing evergreen shrubs & trees,long warm dry summers,found in coastal areas |
|
mountain biome |
snow peaks that reflect solar radiation and gradually release water,biodiverse,regulate climate |
|
Savannas |
tropical grassland,scattered trees,enormous herds of large animals,warm year round,wet & dry seasons,birth place of mankind |
|
niche specialization |
minimizes competition among herbivores in the savanna Ex: giraffes feed at the top of the tree,elephants feed at the bottom |
|
inland/coastal wetland |
inland=freshwater, coastal= salt water |
|
ocean life zone |
buoyancy,prevents life from drying out & becoming too hot and cold, medium for eggs & larvae, no need to conserve,filter UV rays, dilutes & disperses pollutants,biodiverse b/c of depth,few habitats,difficult to count organisms,less common for endemicism,plants are microscopic,smaller herbivores than on land,foodwebs more complicated,high reproduction,short life cycles,species separated from parents at birth,difficult to monitor |
|
ocean layers |
1. surface (euphotic zone) 2.middle (bathyal zone) 3.bottom (abyssal zone) |
|
factors that determine # of organisms & types |
temperature,sunlight,dissolved oxygen, nutrients |
|
coastal zone |
10% of earth's ocean area, but contains 90% of marine species.High PPP,warm,nutrient-rich,shallow,from high tide to gently sloping. |
|
Why are coastal wetlands and estuaries the most productive
|
All of the nutrients flow into it. |
