Bell Question 1. Which alternative energy source uses the energy from the Earth’s interior (core) for power? 2. Which alternative energy source uses the sun’s light for power? 3. Which type of fossil fuel is made of compressed plant remains, and is solid in form?

Nonrenewable vs. Renewable Resources

GOAL To be able to distinguish between renewable and nonrenewable resources.

REVIEW What are fossil fuels composed of? (How are they created?)

REVIEW What are the three types of fossil fuels?

REVIEW Compare the benefits and consequences of using fossil fuels

REVIEW Determine which alternative energy source holds the most promise for use in the future. Support your opinion with a fact.

REVIEW Differentiate between hydroelectric and tidal power

REVIEW Differentiate between hydrogen and nuclear energy

Pair Activity Nonrenewable resources include –Oil –Coal –Natural Gas See if you can come up with atleast 3 more resources that the Earth provides us with (either renewable or nonrenewable)

Nonrenewable Resources When they are used up, they cannot be replaced by nature

Nonrenewable Resources Nonrenewable Resource Examples 1. Fossil Fuels –Coal –Oil –Natural Gas

Nonrenewable Resources Nonrenewable Resource Examples 2. Minerals- mined, dug out of rocks and soil –(Metals, gemstones)

Renewable Resources Resources that are continuously replaced by nature

Renewable Resources Renewable Resource Examples 1. Land –USES: Soil Area for cities, farms, forests Produces food

Renewable Resources Renewable Resource Examples 1. Land- Problems –A. Dry

Renewable Resources Renewable Resource Examples 1. Land- Problems –B. Overgrowing crops

Renewable Resources Renewable Resource Examples 1. Land- Problems –C. Erosion

Renewable Resources Renewable Resource Examples 1. Land- Problems –D. Desertification

Soil Degradation

Renewable Resources Renewable Resource Examples 2. Water –USES: for drinking, cooking, bathing, cleaning

Renewable Resources Renewable Resource Examples 2. Water –USES: Water cycle purifies

Renewable Resources Renewable Resource Examples 2. Water –PROBLEMS: Limited amount of freshwater 97% in oceans

Renewable Resources Renewable Resource Examples 3. Animal Resources –USES: Provides food and other products

Renewable Resources Renewable Resource Examples 3. Animal Resources –PROBLEM: using too much

Natural Resources Use your earth science book to answer the questions pertaining to the renewable and nonrenewable resources of the planet.

Use your earth science book to answer the questions pertaining to the Earth’s resources. 1. What is solar energy and what its advantages and disadvantages? 2. Describe the process of nuclear power? 3. What are 3 obstacles in developing wind power? 4. What is hydroelectric power and how does the process work? 5. Is geothermal energy renewable or nonrenewable and how is it used? 6. How is tidal power harnessed and where is most useful and least useful? Natural Resources:
