Environmental Idol Period 11 by Mrs. Sandoval https://padlet.com/csando27/f8pkhgc0f8fv Honors World History en-us 2017-05-16 11:23:46 UTC 2017-05-25 11:17:21 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Apple.png Acid rain (rachel,Rosario,Kristina) https://padlet.com/csando27/f8pkhgc0f8fv/wish/172650229 Define: includes acid rain, snow, fog, hail, dust
-rainfall turned very acidic
-due to atmospheric pollution
-due to burning coal and fossil fuels-- waste gases from chemicals in fossil fuels combine with atmosphere's water to make acids

Causes: caused by a chemical reaction when sulfur dioxide and nitrogen oxides are released into the air. These substances mix with water and oxygen to fall down again as acid rain.

Effects: -affects lakes, streams, wetlands by making the water acidic
-water absorbs the aluminum from the soil
-harms organisms living in the water
-the rain removes minerals and nutrients from soil, harming plants and their consumers]]> 2017-05-18 17:40:05 UTC https://padlet.com/csando27/f8pkhgc0f8fv/wish/172650229 Acid Rain- Bill, Nick, Chris https://padlet.com/csando27/f8pkhgc0f8fv/wish/173211360 DEFINITION:
Acid rain is any form of precipitation with a lower than neutral pH of 7 due to high concentrations of acid-forming chemicals.

CAUSES:
Acid rain is caused by a chemical reaction when acidic compounds such as sulfur and nitrogen oxide are released into the atmosphere and interact.
Sources of such chemicals are most commonly factories or volcanic activity.

EFFECTS:
Acid rain leaves behind acidic compounds which are absorbed into the soil and water which is detrimental to aquatic, animal, and plant life. Additionally, when inhaled by humans it can cause lung and heart damage though it most likely will only lead to short term illness. It can also erode natural features and man-made structures.

The action of clearing a wide area of trees. Clearing forests. Intentional destruction of trees and other vegetations.

CAUSES:
- logging
- creating agricultural expansion
- livestock ranching 
- infrastructure expansion
- overpopulation

EFFECTS:
The effect is that there is a loss of habitat for millions of species. Drives climate change. More greenhouse gases entering the atmosphere and promotes global warming.

CAUSES: "the greenhouse effect" human overuse of greenhouse gases  (carbon dioxide, water vapor, etc.) and they are absorbed into the lower atmosphere to keep the sun and it's heat in the atmosphere, increasing temperatures.
EFFECTS: 
•Hotter heat waves 
•ocean temperature increase
•ice caps melt, sea level rises
•stronger storms
•extinctions (polar bears, coral reefs, etc) ]]> 2017-05-23 17:32:52 UTC https://padlet.com/csando27/f8pkhgc0f8fv/wish/173454701 Endangered species https://padlet.com/csando27/f8pkhgc0f8fv/wish/173455270 Definition:
a species of animal or plant that is seriously at risk of extinction.

Causes:
-loss of habitat 
-climate change
-human activity 
-human development
-loss of genetic variation 


Effects:
-imbalances in the food chain
-if one species goes extinct then the other species that rely on it will go extinct also

- a colorless unstable toxic gas with a pungent odor and powerful oxidizing properties
- formed from oxygen by electrical discharges or UV light

Causes:
- Occurs when chlorofluorocarbons (CFCs) are formerly found in aerosol spray cans and refrigerants, which are then released into the atmosphere
- From several chemical reactions, these gases cause the ozone molecules to break down 
- This reduces ozone's ultraviolet radiation-absorbing capacity

Effects:
- Ozone can damage the lungs when inhaled
- Skin disease will increase
- Plants will die

-the introduction of a poisonous or harmful substance into an environment

Causes: 
-excessive trash
-chemical spills 
-toxic waste
-pesticides

Effects:
-air, water, and land is contaminated 
-cancer
-death
-skin rashes 
-developmental problems in young children]]> 2017-05-25 00:58:58 UTC https://padlet.com/csando27/f8pkhgc0f8fv/wish/173738116 Ozone https://padlet.com/csando27/f8pkhgc0f8fv/wish/173796225 Definition:
a layer in the earth's stratosphere at an altitude of about 6.2 miles (10 km) containing a high concentration of ozone, which absorbs most of the ultraviolet radiation reaching the earth from the sun.
 
Causes:
Gases like chlorofluorocarbons, coming from aerosol cans, refrigerators and air conditioners, and chlorine have chemical reactions with the layer. Single molecules of any of these substances can decompose thousands of ozone molecules.
 
Effects:
This take away from the protection of the sun’s intensity meaning the sun will be more scorching hot on the earth. We only receive 1% of the sun’s rays meaning that if the ozone layer gets completely diminished, it will be unsurvivable. This will increase climate, and things like skin cancer and sunburn.
