What is the definition of an environment?
All of the living and nonliving things that surround you
What is an ecosystem?
A specified area in our environment containing living and nonliving things
What is the Greenhouse Effect?
A natural process that warms the Earth by trapping the sun’s heat
Are greenhouse gases good or bad?
A lot of greenhouse gases are a bad thing, but a few of them are good because they allow for the Greenhouse Effect to happen
What cause Greenhouse Gases to build up?
Fossil fuels such as oil, coal and natural gas being burned and they release Carbon Dioxide
What are examples of Greenhouse Gases?
Methane Carbon Dioxide Ammonia Sulfur Dioxide
What is the Ozone Layer?
The thin layer of gases in the stratosphere that is made up of the ozone gas
What is the chemical symbol for the Ozone Gas?
Is the Ozone layer man-made or naturally occurring?
What is the purpose of the Ozone Layer?
The Ozone Layer filters out the harmful UV Rays as they reach our atmosphere, but let through the warmth and visible light
Could life on Earth exist without the Ozone layer?
Is the Earth getting warmer or colder because of the increasing amount of Greenhouse Gas?
The Earth is getting warmer
What is water pollution?
Water being contaminated with harmful substances as a consequence of human activities.
What are three sources of water pollution?
1. Factory Dumping 2. Oil Spills 3. Garbage 4. Fertilizers 5. Sewage and waste water
What are two effects of water pollution?
1. Death of aquatic animals and plants 2. Disruptions of food chains 3. Diseases 4. Destruction of ecosystems
What is waste?
Anything that we throw away or get rid of that doesn’t get used
What are some things that create waste?
O Paper O Food scraps O Yard Waste O Glass O Metal O Plastic O Clothing O Wood O Packaging O Electronics
Where does the garbage we create go?
Trash is put into a dump or a landfill
What is a landfill?
A place where trash is left in one spot on top of the ground or in deep holes in the earth, which are filled with trash
Why is plastic such a problem?
On 8% gets recycled and the rest ends up in the garbage and doesn’t decompose
What is a natural resource?
Resource that come from the earth, but are not always found close to home
What is a renewable resource?
Resources that will not disappear as we use them
What is an example renewable resource?
1. Wind 2. Solar Energy 3. Hydro Energy
What is a nonrenewable resource?
Resources that cannot replace themselves once they are gone
What is an example of a nonrenewable resource?
1. Oil/Petroleum (gas, diesel, propane) 2. Natural Gas 3. Coal 4. Uranium
Why do we need to conserve our natural resources?
We protect animals and their habitats We provide a future for generations of people to come
Why does it mean to reduce something?
To make something smaller or use less of resulting in a smaller amount of waster
Why does it mean to reuse something?
We can reuse materials in original form instead of throwing them away Or Pass those materials onto someone who can use them
Why does it mean to recycle something?
Materials can be remade into the same kind of object or into something new
What is a habitat?
The natural home or environment of an animal, plant or organism
Why are we losing habitats?
1. Global warming 2. Deforestation 3. Cutting down habitats for farmland 4. Water pollution
Why is a food chain?
The order in which organisms or living things depend on one another for food
What is a producer?
Organisms that produce their own food
What is an example producer?
What is a consumer?
Anything that eats plants and animals
What is are the three types of consumers?
Herbivores Carnivores Omnivores
What is an herbivore?
An animal that consumes only plants
What is an omnivore?
An animal that consumes both plants and animals
What is an carnivore?
Consumes only meat
What happens if something in a food chain disappears?
It causes problems for all of the other animals on the food chain
What is a food web?
A food web is a group of food chains within an ecosystem
Notes: Geology Chapter 3
THE HUMAN IMPACT ON ECOSYSTEMS Pollution and Overpopulation can seriously damage the health of an ecosystem (the living and non-living factors in an area).
HUMAN CAUSES OF ENVIRONMENTAL CHANGE Biology EOCT Review.
Human Impact on Ecosystems
Overpopulation ~7 billion people Many natural resources are nonrenewable More people means: –1) More forests removed –2) More resources consumed –3)
AND SOLUTIONS! Environmental Issues. The environment is all connected! (p.87) Environmental issues fall into three general categories: 1. Human population.
Aim: How is the earth's atmosphere similar to a greenhouse?
Living It Up What do living things need to survive?
Biomes and Conservation
Conservation and Pollution
Environmental Health BEFORE THE BELL: Get out your journal and writing utensil…

< BackNext >PreviewMain Section 1 Environmental Problems Warm Up 10/19 What is the difference between a renewable resource and a nonrenewable resource?
Pollution. Smog smog – mixture of chemicals that forms a haze in the air (Nitrogen Oxides etc) smoke from cars and factories release the chemicals.
Saving the World… One problem at a time. Pollution -harmful substances, natural or man-made, in the environment -landfills, garbage, etc. -chemicals,
Natural Resources How are resources used? What are the effects of using natural resources?
