We rely on fossil fuels for electricity and transportation.
True
False
Adding carbon dioxide to atmosphere has what effect on the globe?
It decreases atmospheric temperatures
It increases atmospheric temperatures
It has no impact
Which of these are causes of air pollution?
Cars
Fertilizer
Leaving Electric devices on/plugged in (phones, lights, clothes dryer)
How does fertilizer get from fields to lakes and rivers?
Tractors might tip over and spill it.
Animals carry it.
Run off during rain storms carry it.
How does air pollution affect humans negatively?
Tiny particles in the air clog our lungs and make it hard to breath and get oxygen (O2) to our heart. Some will die.
Air Pollution adds gasses to the atmosphere that thickens the blanket around the planet and increases the global temperature.
Air Pollution leads to higher temperatures which leads to melting glaciers which adds water to the oceans.
Air Pollution leads to higher temperatures which leads to more evaporation which means more water vapor in the air which leads to more sever storms.
Farms are great! But they do impact the ecosystem. Which of these are negative impacts of poor farming techniques?
Habitat Loss for wild animals
Fertilizer runoff leading to Eutrophication in lakes and rivers
More food for wild animals
More food for humans
Soil Erosion
Which of these would have an effect on the populations in a forest? (pick 3)
Building a shopping center
Drought (low rainfall for a long time)
Forest fire
A rainy day
Warm sunny days
If the Prairie Dog population decreased which populations would be affected?
With fewer prairie dogs the grass would grow better.
With few prairie dogs there would be less food for the Coyotes
With fewer prairie dogs and coyotes there would be less food for the vultures.
The other populations would feel little affect.
Extra carbon in the atmosphere could...
Lower the temperature around the globe
Act like a blanket for the planet and raise the temperature.
Disappear
Cause the water and nitrogen to disappear.
Which of these wouldn't happen to the water cycle as a result of rising temperatures.
More water could evaporate causing some places to become drier.
People would have to run the A/C more which would add more Carbon to the atmosphere, which would cause more melting ice.
Glaciers and Sea Ice melt, raising ocean levels.
People will plant more gardens.
Eutrophication (too much Algae and Phytoplankton in the water due to too much fertilizer runoff) can lead to...
lower oxygen levels
higher oxygen levels
cleaner water
more aquatic life
A Population's size is determined by the amount of resources. The population can't get grow larger than the resource that is in the shortest supply. This resource that is in short supply is called the ...
Natural Resources
Population Limiter
Limiting Resource
Limiting Factor
This is a Silt Fence. Which of these could it help prevent?
Erosion leading to sediment build up in a lake
Deforestation and habitat loss
Climate change and melting ice caps
Spray fertilizer causing air pollution
What is an effect of deforestation?
decrease in biodiversity
decrease in rainwater runoff
decrease in carbon dioxide in the atmosphere
decrease in the amount of water on earth
How are surface mining and peat harvesting similar in the way they affect an ecosystem?
both increase air pollution, causing acid rain
both flood the area with water, decreasing soil erosion
both release carbon dioxide, decreasing global temperatures
both remove vegetation in the area, destroying habitats
