What is the difference between renewable and nonrenewable resources?

Back

Renewable resources can be replenished naturally over time (e.g., sunlight, wind), while nonrenewable resources exist in finite amounts and cannot be replaced once used (e.g., coal, oil).

What is coal?

Back

Coal is a fossil fuel formed from the remains of ancient plants that have been subjected to heat and pressure over millions of years.

Front

Why is coal considered a nonrenewable resource?

Back

Coal is considered nonrenewable because it takes millions of years to form, and the rate of consumption by humans far exceeds the rate at which new coal can be formed.

What is solar energy?

Back

Solar energy is energy harnessed from the sun's rays, which can be converted into electricity or heat.

Front

What is wind energy?

Back

Wind energy is the energy obtained from the movement of air, which can be converted into electricity using wind turbines.

Front

What is geothermal energy?

Back

Geothermal energy is heat energy generated and stored in the Earth, which can be used for heating and electricity generation.

Front

What is hydroelectric power?

Back

Hydroelectric power is electricity generated by using the energy of flowing water, typically from rivers or dams.

Front

What is the role of turbines in energy generation?

Back

Turbines convert kinetic energy from wind, water, or steam into mechanical energy, which is then converted into electrical energy.

Front

What is the significance of sunlight in renewable energy?

Back

Sunlight is a crucial renewable energy source that can be harnessed for solar power, providing a sustainable and clean energy option.
