Unit 5: Transfer of Info & Energy (I.6E, I.6F, I.6G)

Why do sound waves travel faster through liquids than through gases (like air)

• The particles in liquids are closer together than in air

• The particles in liquids are farther apart than in air

• The sound waves are magnified in liquids

• The sound waves are minimized in liquids

Renewable energy sources are globally equitable. This means...

• Renewable energy sources are implemented to all regions and countries around the world

• Renewable sources bring in a lot of money to all countries and regions globally

• Some countries and regions around the world have a lot more access to renewable energy sources than others

• All countries and regions around the world have access to a fair and proportionate share of renewable energy sources

Which statement summarizes the chart?

• UV rays are more effectively blocked by lead and concrete than Gamma Rays

• All wave types travel through different types of mediums the same way

• Gamma Rays are more effectively blocked by Air and Glass than UV rays

• Both wave types are unable to travel through a vacuum

Why might countries choose to use natural gas despite it's serious environmental disadvantages?

• Natural gas is cleaner than other fossil fuels, energy-dense, and affordable.
• Natural gas produces more carbon emissions than oil.
• Natural gas is more expensive than coal.
• Natural gas is the only available energy source.

Most nonrenewable sources are found below Earth's surface. Is this an advantage or disadvantage and why?

• Advantage: Because they are deep below the surface, they can't be easily stolen

• Advantage: Because they are deep below the surface, they are easier to extract

• Disadvantage: Because they are underground, more people must be employed to extract them

• Disadvantage: Extracting these resources may cause habitat destruction, dangerous work conditions, and pollution
