Unit 2.B

Decay occurs at slow rates Poor nutrient soil Warm temps throughout the year, lots of rain Climbing or flying animals Deforestation, overhunting, and farming

Even rainfall all year Warm/hot summers but cool/cold everytime else High nutrients bc of falling leaves Most altered biome

Regular rainfall throughout year Very cold winters High soil acidity and poor nutrients Low plant diversity Migratory birds

Long, wet winters but short drier winters Clay and sandy soils High nutrient soils Migrating animals or hibernation Climate change

Prolonged dry season Hot summer, warm winters Low minerals, high aluminum levels Grasses die during dry season and return during wet

Hot summers, cool winters Extremely nutrient rich Grasses die in winter, flowers are fast growing to complete life cycle b4 winter

Very cold Organic matter is slow to decompose Permafrost prevents snow/ice from permeating ground Migrating mammals Too cold for much human activity

Dry summers, wet winters Not very fertile Seeds require burning Deep roots Animals adapted to dry conditions

Rare precipitation Slow nutrient cycle due to little bacterial activity Takes decades to recover from disturbances Nocturnal animals Off-road vehicles, mining, oil drilling

Rain that has touched the ground

Areas of land where all the storm water washes to the same location

Emitted by a single, large output of pollution.

Emitted by a large number of small sources.

Addition of nutrients into a body of water

Anthropogenic input of nutrients

Areas of water with so little oxygen that so many things die or can’t live. Low dissolved oxygen levels

How see-through water is

The amount of oxygen required by organisms in a water amount.

Traditional storm water management systems catch and move stormwater runoff towards a discharge point

Stormwater management approach that attempts to mimic the natural hydrologic cycle Uses runoff on the site where it falls

Low density development around cities and towns

Concentrated heat from cars, factories, light, AC, dark roofs, etc. In cities

Collection of principles that address the negative impact of sprawl and encourage municipalities to manage growth and development better

Thin, fibrous silicate material used as insulator
