What is Energy from Earth’s hot interior?
Geothermal Energy
Looking at Map A in the Map Slides. What are the areas in red telling us?
The regions in red are the hottest-known geothermal regions.
Though many oil fields are found on land, there are also vast pools of oil located underwater. There are several issues related to offshore drilling and a number of oil rigs designed to address these issues. These types of rigs include the following:
• fixed platform rigs
• floating production systems
• drill ships
• spar platform rigs
If a large offshore oil field is found, what should the engineering team do before choosing the best rig to use?
2. analyze the advantages and disadvantages of each type of rig
What is a liquid that formed millions of years ago from the burial of marine organisms; can be used as a source of energy?
Petroleum
Scientists can calculate the average soil loss (A) with the formula A = R x K x LS x C x P
If...
R = 18.60
K = 0.320
LS = 0.55
C = 1
P = 1
Then what is the average soil loss rounded to the thousandths?
A = 18.60 x 0.320 x 0.55 x 1 x 1 = 3.274
What is the use of natural resources in a way that ensures their availability to future generations of humans?
Sustainable
Looking at Map B in the Map Slides. What does the key represent?
About 25 percent of the United States’ drinking water comes from groundwater sources. However, groundwater supplies are often nonrenewable resources. This can be due to several factors. Which one of the factors below is due to human influences on groundwater?
2. Pumping of the water.
What is the transfer of energy between objects that are touching; causes energy to move from the warmer object to the cooler object?
Conduction
Look at Table A in the map slides. One of the criteria for a construction project is that average soil loss be less than 3.0 tons of soil per acre per year. Based on the data the scientist collected, which of the possible building sites meets this criterion?
2. Site 2
What is a natural resource that is used up faster than it is replenished, or exists in a limited supply.
Nonrenewable Resource
Looking at Map C in the Map Slides. What does the key represent?
The Major Copper Ore Deposits.
Hank drives by an enormous copper mine while on a road trip. He knows that globally, people are using more and more copper every year. He wonders what the effects of mining are for different living things.
Which of the following is NOT likely to be true about the copper mine Hank saw?
1. Many different kinds of species live near the copper mine.
What is a rock that contains a large amount of valuable elements; can be mined for a profit?
Ore
The engineering team can reduce soil loss by covering the bare soil at the construction site. One of the cheapest and easiest soil covers is straw mulch. Straw mulch has a soil covering value of 0.28. Using this value in the formula, calculate the new average soil loss for each site.
Round to the nearest thousandth place.
Example: Site 1
18.60 x 0.320 x 0.55 x 0.28 x 1 = A = 0.917
Site 2: A= 0.094
Site 3: A= 1.131
Site 4: A= 5.388
What is a mixture of rock and mineral particles, living and once-living matter, water, and air?
Soil
Looking at Map D in the Map Slides. What is one region where would you expect there to be minimal soil fertility?
North Africa, Parts of Australia, Southwestern US, Regions of the Middle East, South South America.
Wood can be a renewable resource that is used for a variety of items. Although forests may be renewable, those that are planted as replacements can take a long time to grow sufficiently to replace those that are cut down. Which of the following solutions could be employed to ensure that a forest is more likely to be a renewable resource?
4. Trees that are cut down are replaced by fast growing trees that can be harvested sooner.
What is the transfer of energy caused by the circulation of matter due to differences in density?
Convection
Looking at the new averages for soil loss, would adding straw mulch allow all the possible building sites to meet the criterion of 3.0 average soil loss?
Site 1: A= 0.917
Site 2: A= 0.094
Site 3: A= 1.131
Site 4: A= 5.388
No, site 4 still has an average soil loss of >3.0.
What is a natural resource that is replenished faster than it is used up, or exists in such great supply that it cannot be depleted.
Renewable Resource
Looking at Map E in the Map Slides. Where would you want to put an aquifer to generate electricity?
Most natural resources take a long time to be replaced and are, therefore, considered nonrenewable. However, the time frame that it takes nature to replenish a natural resource varies depending on the resource. Think about how each of the resources listed below are formed, and organize them on the time scale line from shortest to longest time to replenishment.
A petroleum
B geothermal energy
C soil
D wood
D/C, B/A
What is a useful source of material or energy that comes from nature.
Natural Resource
Suppose that the engineers had to building on Site 4 but soil needed to needed to meet the 3.0 criterion. To meet the criterion, the team must use a soil covering practice. The team had the following four soil coverings to choose from:
• fiber mat: 0.24
• coconut fiber: 0.12
• straw mulch: 0.28
• wood fiber: 0.22
Which of these soil coverages would allow site 4 to meet the average soil loss criterion?
1. fiber mat
2. wood fiber
3. straw mulch
4. coconut fiber
4. coconut fiber
