What is one of the dangers of fracking?
Ground fires can be ignited
Contaminating drinking water
Takes up large areas of land on the surface of the Earth
It is a highly explosive process that can blow up houses

What are some similarities between renewable resources?
They create a lot of pollution
They produce electricity cheaper than fossil fuels
Clean no pollution
Are a highly explosive and dangerous energy source
What are some similarities between nonrenewable resources?
They are unreliable energy sources
They produce electricity cheaper than most renewable sources
Clean no pollution
Are a safe alternative when dealing with global warming
What are some positive and negative qualities of Coal?
Provides many jobs but creates pollution; acid runoff, and mine collapse
Almost all emissions are water vapor but location of plants and waste disposal are a problem
Are a safe alternative when dealing with global warming
No pollution but Weather dependent
What are some positives and negatives when dealing with solar energy?
Provides many jobs but crates pollution; acid runoff, and mine collapse
Almost all emissions are water vapor but location of plants and waste disposal are a problem
Are a safe alternative when dealing with global warming
No pollution but Weather dependent
What happens at oil refiners?
Oil is fracked into different materials
Impurities are added to the oil
Oil is heated and at various temperatures can be separated into usable products
Biomass chemicals are burned to produce energy
Why can fossil fuels be thought of as stored solar energy?
The Sun is always shinning
Fossil fuels start out as plants and plants need sunlight to grow
The Sun created fossil fuels when it created the planets
100's of millions of years ago there was no energy other than the Sun
What type of coal has the highest percentage of carbon and gives off the most energy (for the same amount)?
Peat
Lignite
Bituminous
Anthracite
Thoroughly trace the flow of energy from the Sun through the food you eat to a glowing light bulb. Please think of the lab section 6 with the hand generator, and this should be put in your own words.
The Sun provides energy to plants, which is then transferred to animals when they eat the plants. Humans consume these plants and animals, converting the energy into mechanical energy using a hand generator, which finally powers a light bulb.
The Sun's energy is directly converted into electricity by solar panels, which then powers a light bulb.
The Sun's energy is stored in fossil fuels, which are burned to generate electricity for a light bulb.
The Sun's energy is used by wind turbines to generate electricity, which powers a light bulb.
