Presentation Transcript

Three types of plate

boundaries

divergent

convergent

transverse


Curves the global wind

patterns

Coriolus Effect


Soil layer where

organic material

is found

OHorizon


They eat dead material

and their waste

enriches the soil

Detrivores


Layer of air where jets

fly

Stratosphere


Layer of air where weather

occurs

Troposphere


Top 3 gases in

atmosphere

nitrogen, oxygen, water vapor


What happens to air at the

equator?

Warm moist air rises up and

out cools and descendes 30o

north and south of equator


Movement of heat in

liquids or gases

convection



How do volcanoes affect

weather?

Ash and microparticles causes

global cooling due to blocking

sunlight from reaching Earth


Convection circuit 0-30o

north and south

Hadley cell


Convection circuit 30-60o north or south of equator

Ferrell cell


Describe La Nada in the Pacific

Warm air rises up on Asian side

heads towards Americas, descends

and returns towards Asia causing

upwelling of nutrients in Pacific

side of Americas


Describe El Nino

There is a reversal and warm

air and ocean water moves

towards the Americas from

Asia


Effects of El Nino

Harsh winter in north and

drought in southern

areas


Water absorbed by

soil in the water cycle

infiltration


General water cycle pattern

Evaporation off water,

condensation, and precipitation


The nitrogen cycle letters

and what each stands for

NNAAD

nitrogen fixation

nitrification

ammonification

assimilation

denitrification


What is assimilation?

Roots take up nitrates


What is denitrification?

Nitrogen returning to

atmosphere


Major two sources of sulfur

in the atmosphere?

Coal burning power plants

and volcanoes


Acid rain gas

Sulfur dioxide


Odd thing about the

phosphorus cycle

Little or no

atmospheric

component


The biotic and abiotic factors

of an area interacting together

ecosystem


Two names for organisms

that make their own

food energy

producers

autotrophs


A species whose health

shows the health of its

environment

indicator species


All the species in one

area interacting with

each other?

community


A group of one type of

species

population


Non-living components

of the environment or

system

abiotic factors


Niche

How an organism lives


Increase in organic material

per unit of time

Productivity


The number of species in

an ecosystem is

species richness


The maximum amount or

population that a habitat

can hold is

carrying capacity


A species that eats an

animal that eats a plant is a

secondary consumer


This law explains why

energy is lost at each trophic

level

2nd law of thermodynamics


Form of energy lost

at each trophic level

Heat



First species to return to

a destroyed habitat…

Pioneer

species


Biome whose primary

vegetation is evergreens

Arboreal forest

or

Taiga


The plants that move in following

a degradation of an ecosystem

secondary

succession



A species critical to the success

of an ecosystem

keystone

species


A species that creates or

improves and ecosystem

foundation

species


Trees that lose their

leaves in winter

Deciduous trees


Weight of organic matter

produced by plants

biomass


Biome with nutrient rich

soil

grasslands or wetlands


Biome soil low in

nutrients

Rainforest


Photosynthesis

sunlight and carbon dioxide

makes sugar and oxygen


Importance of predators

- limit populations

- keep genetic strength of

prey by killing old or ill


Relationship that helps

one and doesn’t effect

another

commensalism


Relationship that helps

both

mutualism




How to estimate population

by tag and recapture?

total # in second collection x # in 1st collection

# marked in 2nd collection


How to calculate population

growth?

births – deaths + imm – emmx 100

current pop


Population doubling time

70 = yrs to double

% growth rate


What are GMOs?

Genetically modified

organisms


What is monoculture (3)?

When a farmer grows one crop

or when a country’s economy

depends on one crop or when

only one variety of a crop is

grown


What is the major cause

of the Gulf of Mexico’s

hypoxia?

nitrates

from

fertilizers


What is the weakness of

economic growth?

Limited

resources


What is sustainable growth?

Depends on services and

uses the 3Rs
