CLIMATE
• the prevailing weather conditions in an area
• made up off 4 abiotic factors -temperature, water, sunlight , and wind

Climate
these factors have influence on the distribution of organisms.
Macroclimate- weather patterns on global, regional and local level
Microclimate-very fine patterns like ones organisms will find under log

Global Climate patterns
Earths global climate is influenced by planets movement and solar energy-Sun warms land oceans and causes cycles of air movement and evaporation, causing variations in latitudinal climate

Regional, Local , and Seasonal effects on climate
• There are regional and local variations that cause climate "patchiness" in biosphere
• -mountains, bodies of water ,seasons

Ocean currents also influence climate along coasts of continents by heating or cooling air masses which meet the land.
-coastal regions tend to me more moist then inland
Bodies of water

Bodies of water
-proximity to water doesn’t always moderate climate though.
- in places like southern California it just absorbs the heat and causes hot weather inland.

MOUNTAINS
Mountains effect amount of sunlight reaching area as well as temperature and rainfall
-those with more exposure tend to be drought resistant
-air temp declines 6˚ Celsius with every 1000 m

Seasonality
• Seasonal changes in wind patterns produce variations in ocean currents
• Turnover- brings oxygenated water from a lakes surface to the bottom and nutrient rich water from the bottom to the surface in spring and autumn.

Seasonality
Earth has a tilt of 23.5˚ it causes seasons.
This causes the tropics to have the longest annual exposure to the sun and least change in seasonal climate.

MICROCLIMATE Forest trees effect micro climate -Things like logs shield animals such as
salamanders, worms and insects from temperature.

LONG TERM CLIMATE CHANGE
• Changing temperature in the future can change the plants and animals living in certain regions• -some animals wont
survive in the changing temperatures ,can cause extinction and species will have smaller concentrations
