Step 1:I'll solve this problem step by step, classifying each energy source as renewable or nonrenewable:
Step 2:: Understand the Definitions
- Renewable energy: Energy sources that can be naturally replenished within a human timescale - Nonrenewable energy: Energy sources that cannot be quickly replaced once consumed
Step 3:: Analyze Coal (Option A)
- Classification: $$\text{Nonrenewable Energy}
- Coal is formed from compressed plant matter over millions of years - It is a fossil fuel that takes an extremely long time to regenerate
Step 4:: Analyze Burning Plant Waste (Option B)
- Classification: $$\text{Renewable Energy}
- Plant waste can be regrown relatively quickly - Biomass can be replanted and regrown within a human lifetime
Step 5:: Analyze Water Springs Inside the Earth (Option C)
- Classification: $$\text{Renewable Energy}
- Geothermal energy from water springs is naturally replenished by Earth's heat - The water cycle and geological processes continuously regenerate this energy source
Step 6:: Analyze Natural Gas (Option D)
- Classification: $$\text{Nonrenewable Energy}
- Natural gas is a fossil fuel formed over millions of years - It is extracted from underground deposits and cannot be quickly replaced
Final Answer
A. Coal - Nonrenewable B. Burning Plant Waste - Renewable C. Water Springs Inside the Earth - Renewable D. Natural Gas - Nonrenewable
