When you go around your school,
have you noticed the school
gardener working in the garden,
always taking care of the soil?
Have you ever wondered why does
he take so much care of the soil?
What will happen, if the soil is
just left like that?
Do you think, it will produce healthy plants?

SOIL

Soil is present all around us. Have you ever wondered, where it comes from?

Actually, soil comes from broken pieces of rocks, dead leaves, tree branches, dead
animals and insects. It takes hundreds of years to turn some rocks into soil.

Formation of Soil

e changes taking place in the

weather help in the formation

of soil. When the weather gets
hot, rocks get bigger. When the

weather turns cold, rocks get
smaller.
