a. solar
b. wind
c. nuclear
d. fossil fuels

1. which of the following is not a renewable energy resource?

a. coal
b. wind
c. solar
d. hydroelectric

1. fossil fuels are classified as non - renewable because they

a. are too expensive to extract.
b. cannot be burned efficiently.
c. take millions of years to form.
d. are found in many countries.

1. which type of fuel runs nuclear fission reactions?

a. iron
b. thorium
c. uranium
d. hydrogen

1. greenhouse gases impact our world by

a. making driving more difficult
b. trapping heat in the atmosphere
c. making earthquakes more common
d. helping planes fly safely in the stratosphere

1. matching

place the correct letter in the correct blank.
a. solar b can be used in rural, windy areas
b. wind a depends on availability of sunlight
c. nuclear d produces carbon dioxide emissions when burned
d. fossil fuels c produces large amounts of energy without greenhouse gas emissions
short answer

1. in your opinion, which energy source has the greatest potential to reduce carbon dioxide, i.e. co₂ emissions? and what are the advantages and disadvantages of that energy source? be specific!

Explanation:

1. Solar and wind are carbon - free energy sources, while fossil fuels are not.
2. Coal is a non - renewable energy resource, unlike wind, solar, and hydroelectric.
3. Fossil fuels take millions of years to form, making them non - renewable.
4. Uranium is used in nuclear fission reactions.
5. Greenhouse gases trap heat in the atmosphere.
6. Wind can be used in rural, windy areas; solar depends on sunlight availability; fossil fuels produce CO₂ emissions when burned; nuclear produces large amounts of energy without greenhouse gas emissions.
7. For the short - answer, common low - carbon energy sources and their pros and cons could be considered. For example, solar energy: Advantage - renewable and clean; Disadvantage - intermittent and high initial cost.

Answer:

1. D. fossil fuels
2. A. coal
3. C. take millions of years to form
4. C. uranium
5. B. trapping heat in the atmosphere
6. B. Wind; A. Solar; D. Fossil fuels; C. Nuclear
7. Answers may vary. For example, solar energy: Advantage - renewable, clean, abundant. Disadvantage - intermittent (depends on sunlight), high initial cost for installation of panels.
