Mod G Unit 2 Lesson 2 - Distribution of Natural Resources

What is the main reason oil deposits are found in some areas but not others?

• Oil forms very quickly and as a result can only form in certain areas.

• Humans depleted the resource in the areas where oil is not found.

• Oil seeped through the rocks and moved to different areas from where it was formed.

• The environment necessary for the oil to form was found only on certain parts of Earth’s surface

The sentences below contain one advantage statement and one disadvantage statement. Both statements must be true and must make valid points.

Which statements best DEBATE the advantages and disadvantages of using renewable energy sources, such as hydropower, solar energy, or geothermal resources?

• Solar energy is extremely inexpensive to harvest.

  Solar energy is available everywhere on the planet.

• Geothermal energy produces enormous amounts of pollution.

  The technology required to collect thermal energy is inexpensive.

• Geothermal energy is more renewable than solar energy.

  Hydropower can change flowing water from a renewable energy resource to a nonrenewable resource.

• Hydropower requires the construction of dams that change the ecology of the river.

  Hydropower will be available as long as the river continues to flow.

Sometimes a renewable resource can be considered nonrenewable because it is used up faster than it can be replenished. Which description is an example of this?

• solar energy being used to provide electricity to a home

• water in streams replaced by rainfall from the atmosphere

• forests being cut down at a quicker rate than they can grow

• coal supply dwindling because it takes millions of years to form

Oil is a limited resource on Earth. In many places, oil is too expensive to obtain using current technological means. Which trade-off best describes this scenario?

• a trade-off between societal practices and the cost of getting oil

• a trade-off between environmental concerns and the need for oil

• a trade-off between the need for oil and the cost of getting the oil

• a trade-off between two types of technology used for getting the oil

Coal is a natural resource. Why is coal considered nonrenewable?

• Coal will never run out.

• No new coal is being produced on Earth.

• Coal is used to produce energy and not materials.

• Coal is being used faster than it is being produced.

The diamonds on Earth formed billions of years ago in Earth’s mantle. The diamonds were brought to the surface by volcanic eruptions. Over time, the volcanic rocks eroded and the diamonds were deposited in sediments. What can you infer about the geologic processes that shaped Russia and Africa from the table?

• Russia has more active volcanoes than Africa does.

• Both Russia and Africa only recently formed as continents.

• Both Russia and Africa had volcanic eruptions in the past.

• More weathering and erosion happens in Russia than in Africa.
