Dirt or soil is very complex, consisting of multiple layers and a variety of living and nonliving oranic material.Kicked around, overlooked, dirt has been given a bad name. However, dirt is just as important to our lives as air, water and sunshine.

We use it to grow our food, shelter us, it acts as a filter to all the toxins we use, it even helps regulate the climate.

Soil is the other "black gold." It takes tens of thousands of years to make about 6 inches of top soil.

So what do you know about dirt?
