4. Which is a positive aspect of fossil fuels?
They provide energy for cars, trains, and heat.
5. Which fossil fuel is considered the most abundant in the United States?

It produces less pollutants than fossil fuels.
9. (this one shows a graph.) Which has been the primary source of energy in the most recent century?
petroleum, natural gas, and coal
10. (also shows a graph) Which renewable resource has been used for the longest time?
hydroelectric power
11. Use the scenario to answer the question.
Edwin buys a water bottle, reuses it twice, and then recycles it. Eleanor buys a water bottle, reuses it twelve times, and then throws it away.
Which energy cost would apply to Edwin, but not to Eleanor?
the cost of processing the bottle after it was no longer used
12. Your class goes on a field trip to observe drilling machinery. The geologists at the drill site show you displays of drilled rocks to compare different types of drills and methods. The drilled holes in one rock display are significantly larger than the holes drilled in the display next to it. Given this information, which statement is correct?
The rock display with larger holes shows petroleum drilling, which is deep underground.
(the last 3 questions are all written responses. These are mine, but make sure to change them up as much as you can. Read it, then change it. I don't want you guys to get into any type of trouble 😊)
13. Ocean waves are a source of energy. In 1–2 sentences, make and justify a claim about whether ocean waves are a renewable or nonrenewable resource:
Ocean waves are a renewable resource since they are created continually by natural forces such as wind and tides, and their energy may be harvested without depleting the resource or affecting the ecosystem. Ocean waves will continue to be a source of energy as long as there is wind and the moon continues to orbit the earth.
14. In three to five sentences, explain the effects of acid rain on the environment:
Acid rain, which is generated by the emissions of sulfur dioxide and nitrogen oxide gases, can have serious environmental consequences. Acid rain may harm and destroy plants and soil, resulting in lower food yields and a loss of biodiversity. It may also cause acidification of lakes and rivers, making aquatic life harder to sustain.
15. Larger companies often need many workers who do different steps in the transportation process, instead of each member doing all steps in the process they do a single step before handing it to another worker to do the next step. Imagine that you are the head of a large company that wants to retrieve raw materials. In three to five sentences, describe three different jobs your company may need and explain the purpose of those jobs:
As the owner of a large company that retrieves raw materials, my company may require the following three jobs:
Mine inspector: A mine surveyor's task is to measure and map the mining site, which includes all tunnels, shafts, and mining regions. The information gathered is utilized for mine planning and excavation design, as well as to ensure the safety of personnel and equipment.
Heavy equipment operator: This position necessitates the ability to operate heavy machinery such as excavators, bulldozers, and dump trucks. They are in charge of transporting enormous amounts of material from the mining site to processing sites or transportation vehicles.
Mineral processing engineer: After extracting the raw material, it must be treated in order to eliminate undesired components and concentrate the precious mineral. A mineral processing engineer creates the process flow and equipment needed to extract minerals from raw ore. They also make certain that the process is optimized for optimum recovery and efficiency while reducing waste and environmental impact.
I just did the test, but your questions might be a little different than mine. If you do not trust me thats alright, but my answer are correct. thank you!
