Where is almost all of Earth’s surface water found? Explain?
Almost all of Earth’s surface water is found in the oceans. Ocean
water is salty and it is not safe to drink. Therefore, most of the
surface water on Earth is too salty for people or animals to drink.
What is water reclamation? Describe it.

homes and offices, so the water can be used again for such
things as watering lawns or washing cars.
