What is the primary gas in the atmosphere causing climate change.
Carbon Dioxide/CO2
Identify a natural resource not used for energy
Any minerals
Which renewable energy source will always emit greenhouse gases?
Biomass
Identify 1 pro and 1 con for using fossil fuels for energy.
Pros: Cheap, abundant (for now), efficient
Cons: Releases greenhouse gases, potential to pollute air/water/land
Each person in the United States generates an average of 2.0 kg of solid waste per day. Much of it is buried in this.
Landfills
Describe the greenhouse effect
Greenhouse gases in our atmosphere trap heat from the sun causing the global temperatures to rise.
Identify 2 human activities that affect the availability of natural resources
Mining
Agriculture
Urban Development
Deforestation
Overconsumption
Which renewable energy source is the most efficient?
Geothermal Energy
What does it mean for a fossil fuel to be clean? Which is the cleanest?
It produces the least amount of pollution
Natural Gas
What are the chemicals that can cause runoff and dead zones called? They can be applied to farm fields to control weeds, insects, and fungi.
Pesticides
Identify some solutions to climate change
Drive less
Switch to renewable energy
Conserve water
Population control
Are natural resources evenly distributed around Earth? Why or why not?
NO!
Reasons can include:
Tectonic plate movement
Uneven heating from the sun
Geography
Weather/Climate
Explain how the generator and turbine model works.
Water is typically heated to produce steam the steam spins a turbine and the rotational movement of the turbine generates electricity
How does nuclear energy work?
An atom of uranium is split which releases energy to heat water that produces steam then spins a turbine
Identify all the reasons for the increased growth of the human population in the last few hundred years.
better healthcare (hospitals, medicines, vaccines)
cleaner water
better sanitation
higher life expectancy
birth rate > death rate
Identify 3 consequences of climate change
Rising sea levels and coastal flooding
Changed rain patterns resulting in droughts and crop failures
Increase in insect diseases in regions
Increase in extreme weather
