Environmental Changes & Ocean Systems

Front 1

ENVIRONMENTAL EFFECTS

Back 1

changes that occur in the environment naturally or by humans that force organisms to adapt or become extinct

Front 2

ENVIRONMENTAL EFFECTS cause

Back 2

habitat loss

Front 3

SHORT TERM CHANGES IN ENVIRONMENT

occur:

Back 3

quickly and affects organism's immediately.

( fast but still takes days, months or years to happen.)

Front 4

NATURAL SHORT TERM CHANGES

Back 4

are caused by drought, flooding, blizzards, forest fires, *earthquakes, hurricanes, volcanic eruption, seasonal changes and tornadoes

Front 5

SHORT TIME CHANGES CAUSED BY HUMANS

Back 5

are smog, *pollution, *oil spills, agriculture,

* deforestation, over fishing, over hunting,

urbanization and energy

Front 6

LONG TERM CHANGES IN ENVIRONMENT

occur:

Back 6

slowly and allows organisms to adapt to the changes and affects for generations; genetic variations

(time to happen-hundred, thousands, millions of years)

Front 7

NATURAL LONG TERM CHANGES

Back 7

are caused by *earthquakes, plate movement, mountain building and temperature

Front 8

LONG TERM CHANGES CAUSED BY HUMANS ARE:

Back 8

global warming, * deforestation, * pollution,

*oil spills and radioactive toxic waste

Front 9

OCEANS help:

Back 9

regulate Earth's heat flow- which affects

weather patterns, water cycle and carbon cycle.

Front 10

EARTH'S HEAT FLOW helps:

Back 10

prevent global warming

Front 11

OCEANS provide:

Back 11

humans with both living and non-living

resources.

Front 12

LIVING RESOURCES from the OCEAN are:

Back 12

minerals, fuel, and water for use as/in food, detergents, shampoos, cosmetics, paints, ice cream and medicine.

Front 13

NON-LIVING RESOURCES from the OCEAN are:

Back 13

minerals, fuel (oil & natural gas),

water (desalination-removal of salt for fresh

water) for transportation and recreation

( boating,diving,surfing)

Front 14

HUMAN DEPENDENCE ON OCEAN HAS

Back 14

BOTH:

positive effects- artificial reefs

and

negative effects- over fishing, pollution

runoff- from household sewage and agriculture waste, oil drilling, and floating garbage.

Front 15

AGRICULTURAL WASTE IN OCEAN CAUSES:

Back 15

dead zones caused pesticides and mercury

deposits & global warming caused by coal burning factories.

Front 16

GLOBAL WARMING

Back 16

happens when ICE CAPS melt which causes sea levels to rise and more frequent hurricanes

Front 17

OIL DRILLING CAN:

Back 17

have leaks or oil spills that hurt or kill off ocean life

Front 18

OVER FISHING

Back 18

is the removal of fish faster than they can

reproduce- there are less or none

Front 19

FLOATING GARBAGE causes:

Back 19

premature deaths when ocean life feeds on the trash

Front 20

ARTIFICIAL REEFS

Back 20

are made by humans sinking old ships or oil rigs which allow coral to build and then attract ocean life,

Front 21

DEFORESTATION

Back 21

when humans cut down and clear all the trees in an area- kills plants and animals, and causes soil erosion.

Front 22

SURFACE RUNOFF

Back 22

when water flows over land and ends up in streams and other bodies of water

Front 23

ALGAL BLOOM

Back 23

when fertilizer enters water it causes large amounts of algae to grow and use up most of the available oxygen causing organisms to die.
