Non-Renewable Sources
What is a nonrenewable source of energy? (Definition)
A source of energy that is being used up faster than it is being produced.
Which of these resources is renewable? Iron, coal, sun, natural gas.
What is sun
What is one of the disadvantages of nuclear energy.
1. Radioactive waste
2. Can lead to leukemia and other cancers and diseases
A city determines the average amount of electricity used by its residents over a year. Which term is used for this specific calculation?
what is per capita consumption
How can a city decrease its per capita consumption of water?
A. It can find a new source of water for the city.
B. It can encourage each citizen to use less water.
C. It can increase the total amount of water available.
D. It can limit the number of new people moving into the city.
What is B. It can encourage each citizen to use less water.
What are the three resources of nonrenewable energy?
Coal, oil, natural gas
Name two renewable sources of energy that are weather based.
Solar, wind
What are 2 sources of biomass?
1. Forestry residue
2. Agicultural residue
3. Sewage
4. Industrial residues
5. Animal residues
6. Solid waste
What has happened to the size of the human population over time?
What is gradually increased until 1880 and then exponentially grew in the last 200 years.
Explain why the industrial revolution was such an important time for the evolution of the economy in the US.
Give 2 disadvantages to using nonrenewable sources of energy.
1. It pollutes
2. It's running out
What are some advantages of using solar power?
- Cheap when set up
- Clean energy
- Efficient
Nuclear energy is created by _
Separating the nucleus of a stable element in a process called fission.
Most cases is Uranium.
In 2016, Japan’s estimated birthrate was 8 births per 1,000 people. The estimated death rate was 10 deaths per 1,000 people. There were not very many people moving into or out of the country. What most likely happened to Japan’s population size in 2016?
What is decreased
A town’s population size has been slowly increasing for the past five years. The town’s total electricity use has also slowly increased, until last year when it decreased slightly. Explain what could have caused the decrease in the town’s total electricity use.
explanation of a factor causing a decrease in resource use in spite of increase in population size (e.g., Individual people used less electricity, causing the per capita consumption to go down or engineering improvements by the city resulted in more efficient energy use.)
Explain how fossil fuels are made.
Dead plants and animals that have been covered with sand and soil so the decaying process is delayed. Then pressure from the bottom of the ocean or the earth turns this decay into coal and oil.
The use of a turbine to turn a generator.
What are two advantages of fossil fuels?
1. Do not rely on weather
2. Relatively cheap to extract and transport
3. Efficient
4. Do not rely on location
Which factor is most likely to cause a decline in a population’s growth rate?
A. increase in birthrate
B. decrease in death rate
C. improvements in medical care
D. high immigration out of the area
What is D. high immigration out of the area
A variety of factors can cause a population’s growth rate to increase or decrease over time.
1. Describe two factors that can cause a population’s growth rate to change.
2. Explain what could cause a population’s size to stay the same.
Sample Answer:
⦁ Increase in birth rate or improvements in agriculture, technology, or public health lead to increase in growth rate, while increase in death rate or immigration out of population leads to decrease in growth rate.
⦁ Birth rate and death rate are equal with no immigration into or out of the population.
To receive full credit, students must describe two factors that can cause population growth rate to change, and explain how a population’s size could remain constant.
Humans use renewable and nonrenewable energy to do work.
1. How do humans use energy resources?
2. Describe two sources of renewable energy.
Sample Answer:
⦁ Humans use energy resources to produce heat, generate electricity, etc.
⦁ Energy resources are powered by the sun or by the movement of wind or water.
To receive full credit, students must explain how humans use natural resources and describe the sources of renewable energy.
Nuclear energy is considered clean energy and it uses uranium, but it is not entirely renewable. Can you explain why?
There is limited amount of uranium, but the amount used for a nuclear plant is so little that it is possible to continue using nuclear power plants for a long time.
Would it make sense to set up solar cells in countries that are further up north? Such as Greenland?
What renewable energy should they consider?
No, they should consider using wind or water enery sources.
In general, how are natural resources and population size related?
A. Natural resource use decreases as population size increases.
B. The rate of natural resource use stays the same as population size increases.
C. As population size increases, more natural resources become available for use.
D. Population size grows faster in places where more natural resources are available.
What is D. Population size grows faster in places where more natural resources are available.
What percentage of the world is made up of desert and mountains?
57%
