Biomes

Biomes

broad type of reigion that vary in latitude and elevation

Most important charactertistics of biomes

temperature and precipation

How many biomes are there?

10

Name the 10 Biomes

tropical forest, tropical grassland, tropical decidous forest, warm forest, cold desert, prairie, temperate deciduous forest, boreal forest, tunda, polar

vertical zonation

typical elevation profile; types of trees; vegetation that changes rapidly from warm and dry to cold and wet; according to height on the desert floor

Why is the United States not the greatest on life expectancy?  

The environment is too polluted and damaged and it is affected due to the systems political, judicial, and cultural, and otherwise that have allowed environmental damage

surface area per unit volume

The smaller something is the more surface area per unit volume; the larger something is the less surface area per unit there is

Deserts

barren, biologically impoverished; sparse but diverse vegetation; warm, dry, high-pressure climate, at 30 DEGREES NORTH AND SOUTH OF THE EQUATOR; in NA, Central Aisa, Africa, AUS, SA (Chile); extreme heat and cold; thick, water storing stems & leaves, salt tolerance; Rain Shadow effects; vulnerable to overgrazing

Tropical Moist forests

what varies in biomes

elevation, latitude, resiliency, and biological productivity

IMPORTANT QUESTION: why is the United State’s life expectancy not the highest?

The political, judicial, and cultural systems that take the most hold on the US have damaged and polluted the environment with years of no substantial environmental protections until the Clean Air and Water Act and the EPA were created

ERAS

toolmaking, agricultural revolution, industrial revolution, technological revolution

Birth Dearth

Falling fertility rates as well as fewer babies; an effect of polluted environment and cultural/societal changes in modernized/industrialized countries

Rain shadow

primarly moisture towards the east of the mountains; any lack of moisture is due to the precipitation unable to get over the mountain; THEY FORM DESERTS

Hardley Cells

spaces of energy transfer between the individual wind patterns within the trade winds
