Impact on Land
The contamination of the environment with substances harmful to life
Pollution
Area of permeable sediment or rock that holds significant amounts of water
Aquifer
Rain or snow that has a lower pH than that of normal rainwater
Acid precipitation
Compare and contrast global warming and climate change
Climate change = long term warming and cooling of areas. Also includes changes to precipitation and wind.
Global warming - only includes the rise in Earth's average surface temperature
Planting trees to replace trees that have been removed
Reforestation
An addition to a river or waterway that changes the overall flow
Dam
The contamination of air by harmful substances including gases and smoke
Air pollution
Give an example of a natural and man-made cause of carbon dioxide
Natural: volcanic eruptions, forest fires, cellular respiration
Man made: burning of fossil fuels, factory pollution, cars
The cutting of large areas of forests for human activity
Deforestation
Describe the effect of excess sediment washing into oceans and other waterways
Excess sediment can clog the filtering structures of marine filter feeders. It can also block sunlight from reaching normal depths. (Other responses possible)
When nitrogen and carbon compounds in the air react with sunlight
Photochemical smog
The loss of color in corals that occurs when corals are stressed
Coral bleaching
The development of land for houses and other buildings near a city
Urbanization
Describe the effects of excess nutrients on water ways.
Excess nutrients in the water could lead to algal blooms. Algal blooms can block out light and harm photosynthetic organisms underwater.
A mix of both solid and liquid particles in the air
Describe one way humans will have to adapt to climate change.
Agriculture (change planting dates, change livestock and/or crops)
Health (Develop heat-health plans, increase climate-related disease programs)
Infrastructure (Relocate at risk communities, expand climate monitoring systems)
The process of restoring land disturbed by mining
Reclamation
Give an example of an organism harmed by plastic waste. Describe how the organisms comes into contact with the waste.
The albatross chicks fed plastic. Fish eat plastics. Humans eat fish.
Several possible responses.
These are released from old refrigerators and air conditioners. They react with sunlight to destroy ozone molecules.
CFCs
Describe the greenhouse effect.
Natural process that occurs when certain gases in the atmosphere absorb and reradiate thermal energy from the Sun.
