Colours of Soil

e soil samples taken from di erent places

have di erent colours. Even their look and

feel are di erent from one another. e colour

and nature of soil depend not only on the
place, but also the depth under the ground,
from where it is taken. Water also a ects the

colour of soil. Wet soil is usually darker than
dry soil. You can know about the weather of a

place by squeezing some soil of that place in
your hands. If soil crumbles between your ngers, then the weather has probably

been dry. If soil is wet and sticky, then it might have rained in the recent past.

Wet and sticky soil is called mud.
