Answer:
Exist in fixed amounts
Cannot be replaced in a short time
Are used faster than they are replaced
Explanation:
Non renewable resources, as the name suggests, cannot be renewed. They are finite resources, meaning they run out. They exist in fixed amounts, which means they are limited. These types of resources can be replaced but it takes a long time. For examples, crude oil. Crude oil is produced by the natural geological occurences but it takes millions to billions of years to be produced. So eventually, we are going to run out of it because people use it up in a significantly lesser time.
