How do you form a zero conditional clause?

A zero conditional clause is formed by using the present simple tense in both the if-clause and the main clause. It is used to talk about general truths, scientific facts, and situations that are always true. The structure of a zero conditional clause is as follows:

If + present simple tense, main clause + present simple tense.

For example:
- If you heat water to 100 degrees Celsius, it boils.
- If it rains, the ground gets wet.

In these examples, the if-clause states a condition that is always true, and the main clause describes the result or consequence of that condition.
