Fossil fuels are non-renewable resources, while solar energy, wind energy, and hydropower are renewable resources.

Multiple choice

What was the main source of power for early mechanical clocks?

  1. Gravity

  2. Electricity

  3. Steam

  4. Wind
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Early mechanical clocks relied on gravity as their primary source of power. A weight was attached to a rope or chain, and as the weight descended, it drove the clock's mechanism.

Multiple choice
