Question

short answer (2 - 3 sentences each): 1. what are fossil fuels, and why are they considered nonrenewable? 2. list two examples of renewable resources and explain how each one produces energy.

Explanation:

1. Fossil fuels are formed from decomposed plants and animals over millions of years. They are non - renewable because their formation takes an extremely long time compared to the rate at which they are consumed.
2. Solar energy: Solar panels convert sunlight into electricity through the photovoltaic effect. Wind energy: Wind turbines capture the kinetic energy of wind and convert it into electrical energy as the blades rotate and drive a generator.

Answer:

1. Fossil fuels are energy - rich substances formed from ancient organic matter. They are non - renewable due to their long - term formation process relative to consumption.
2. Solar energy: Sunlight is converted to electricity by solar panels via the photovoltaic effect. Wind energy: Wind turbines transform wind's kinetic energy into electrical energy as blades rotate a generator.
