Question

Earth acts as a natural filter for water,how?please try to understand my question please​

Answer 1

Answer:

In nature, water is filtered through layers of soil, sand, rock, and other natural materials like leaves. Surfaces where water can penetrate are called permeable surfaces. Impervious surfaces, like rooftops and paved roadways, are surfaces where water cannot penetrate.

Answer 2

Answer:

The different layers of earth's crust acts as the layers used in filters to purify water. For example the earth contains porous rock that are permeable and lets the water through it while retaining the other particles. Apart from this the earth is rich in minerals hence it does keep the water full of useful minerals.
