why is the dirt brown?

Answer 1

There is no such thing as dirt. Dirt is actualy ground up rock mixed with various amount of organis material...the color of the dirt reflects the color of its orginal parent material. So dirt is not only brown ...its red (around here almost all dirt is red clay), its white (have you ever seen beach sand), the black (look at the gumbo mud dirt in a river bottom). Dirt is the color of the material it came from

Answer 2

Some dirt is brown-some dirt is black-some dirt is red-some dirt is sandy. Is all your dirt just plain old brown? After reading I am I said I should be in Oklahoma. Where i dug deep in the front the clay was yellow and pure white. To get grass to grow there i had to move grass and more dirt in other parts of the yard a little at a time. It grows there now!

Answer 3

Dirt is brown because it reflects those colors of the spectrum in sun or artificial light.

With no light present, it is black.

When I pull my red truck into the garage, close the door and turn off the light, it is a black truck.

I thought perhaps this is a trick question, because dirt comes in all colors; ie, Iowa=black, Oklahoma=red, Texas coast=tan, etc,etc...

Answer 4

Not all dirt is. Some is pure white, some yellow, some is red and some is black. It depends on where in the world you are and the composition of the minerals which provide pigment for it.

Answer 5

It depends on the type of nutrients and chemicals that are in the soil. Red soil has a lot of iron in it. White soil has a lot of calcium. Sand is made up of silicate. Soils rich in organic matter are dark so brown and black soils have higher amounts of organic matter in them than lighter coloured soils.
