Question 1

Smog

Accepted Answer

A haze that forms when exhaust is trapped near Earth's surface

Question 2

Groundwater

Accepted Answer

Pollution that is  most concerning because it is a major source of drinking water.

Question 3

Population

Accepted Answer

Too many people using limited resources.

Question 4

Runoff

Accepted Answer

It often carries chemicals, oil, and sedimemt from roads and land surfaces.

Question 5

decrease in oxygen produced

Accepted Answer

A problem that occurs from deforestation.

Question 6

CFC's chlorofluorocarbons

Accepted Answer

harmful man-made gases that contain chlorine, fluorine, and carbon

Question 7

Pollution

Accepted Answer

pollution has many adverse influences on air, water and land.

Question 8

Atmospheric Changes

Accepted Answer

Greenhouse gases due to the burning of the fossil fuels depleting the ozone layer.

Question 9

Endangered Species

Accepted Answer

species are threatened by extinction due to habitat destruction.

Question 10

Invasive Species

Accepted Answer

non-native plants, animals, or pathogens that spread rapidly and cause significant economic, environmental, or health problems

Question 11

Overpopulation

Accepted Answer

Too many people in a particular area
-Pollution
-Greater use of FINITE resources
-Loss of Biodiversity
-Overuse of Land

Question 12

Biodiversity

Accepted Answer

The variety of plant and animal species living in an environment.

Question 13

Acid Precipitation

Accepted Answer

Result of burning fossil to make power.
Rain mixes with toxic gases (sulfer dioxide (SO2 ) and nitrogen oxide (NO) in the air.
Acidification of lakes and streams killing fish, frogs and coral.
Damage to tree leaves at higher elevations due to acid fog.

Question 14

Methane

Accepted Answer

A strong greenhouse gas produced by cattle, sheep, landfills, farming anf fossil fuel extraction.

Question 15

Ozone

Accepted Answer

A gas in the atmosphere that helps block harmful UV rays and is also a greenhouse gas.

Question 16

Human Impact on Biodiversity

Accepted Answer

loss most often due to human activities:
Harvesting
Poaching (hunting)
Deforestation
Pollution
Oil Spills
Mining

Question 17

Habitat Destruction

Accepted Answer

Caused by:
Deforestation
Oil Spills
Mining
Draining Wetlands
National Work Projects
Animals displaced - Less biodiversity means less stability

Question 18

Farming

Accepted Answer

Use of fertilizer and pesticides runoff into waterways.

Question 19

Acid rain

Accepted Answer

Precipitation with a low pH

Question 20

Overharvesting

Accepted Answer

the unsustainable removal of natural resources—such as fish, timber, or wildlife—at rates faster than they can naturally regenerate. Also known as overexploitation

Question 21

Invasive Species

Accepted Answer

The release of a non native species into a new environment.
Non native species quickly overpopulate due to lack of natural predators. (apply to animals and plants). Out compete native plants and animal.

Question 22

Land and Soil contamination

Accepted Answer

Created by humans polluting land and soil with waste and toxic chemicals,  these toxins are passed along to the food webs/chains.

Question 23

Global Warming

Accepted Answer

Burning of fossil fuels (gasoline, coal and oil) increasing CO2 pollution in the air, potentially increasing the earth's temperature.

Question 24

Carbon Dioxide CO2

Accepted Answer

Greenhouse gas released by burning fossil fuels and cutting down forests.

Question 25

Ozone Depletion

Accepted Answer

use of CFCs (chlorofluorocarbons)  that lowers ozone by breaking up O3
- Found in aerosol cans, refrigerator and air conditioner emissions
- CFCs create a hole in the ozone layer
- Ozone layer prevents UV radiation from reaching the earth.

Question 26

Effects of UV Radiation

Accepted Answer

Increase in Mutations
Increase in cancer
Destroys aquatic producers disrupting food chain
