Question

How are coal and oil similar?

Both coal and oil are renewable resources.
Both coal and oil must be mined from underground.
Both coal and oil are used to make natural gas.
Both coal and oil are gases.

Answer 1

The correct statement regarding the similarities between coal and oil is:

**Both coal and oil must be mined from underground.**

However, it's important to clarify a few other points:

- Both coal and oil are **non-renewable** fossil fuels, not renewable resources.
- Oil is not mined; it is extracted through drilling. Coal is mined from underground or surface mines.
- Natural gas is a separate fossil fuel that can be derived from oil but is not made directly from coal or oil.
- Coal is a solid, while oil is a liquid, so they are not both gases.

Overall, the mining aspect is the main similarity in the context provided.
