Understanding Soil Profile Video Lecture - Class 7

what a soil profile a vertical section
cutting through the soil showing the
different layers of the Solent is called
a soil profile soil profile can be seen
by looking at the sides of a recently
dug trench or while digging a well or a
foundation of a building soil has three
different layers top soil subsoil and
substratum cap soil it is the most
useful part of the soil it is dark in
color because it is rich in minerals and
humans plant roots also grow in the
topsoil many living things like insects
worms bacteria and rodents live in the
topsoil
it contains the decayed remains of dead
plants and animals which forms humors
humans makes the topsoil very fertile
subsoil the layer of soil just below the
topsoil is called subsoil it is lighter
in color and has little humors it is
leader of slightly bigger rock particles
which makes it harder and more compact
it contains very little living organisms
substratum the layer of soil just below
the subsoil is called the substratum it
mainly consists of partially broken or
weathered rocks these rocks keep
breaking from the bedrock which is just
preload substratum
it is this bedrock that has produced
soil over a long period of time there
are some important climatic factors
which affect the soil profile and bring
changes inside
