It's about the land pollution that's happening now and before.

2. Define the conceptual terms soil,
land and minerals; and
Identify activities that causes
land pollution and their effect on
the environment.

3. Minerals are elements or
compounds which are solid,
inorganic, and naturally
occurring. They are often
combined with other substances.
Appropriate amounts of
nitrogen, phosphorus, and
potassium are components of
fertile soil.

4. Prof. Ernesto Serote described the
land as:
a natural resource
an economic good
a property
a territory

5. Soil is the material that makes
up the topmost part of the
crust.
The pedosphere is the thin
outermost layer of the Earth
made up of soil.

6. IMPORTANCE OF SOIL
Many ecosystems depend largely
on the soil.
It provides the nutrients which are
vital for plant growth.
It also allows water, air, and
energy to flow through it,
providing other resources which
are critical for the survival of
species.

7. HOW DO SOILS FORM?
WEATHERING
It is the breaking
down or dissolving
of rocks and
minerals on
Earth’s surface.

8. HOW DO SOILS FORM?
Soil is formed from
accumulated sediments,
weathered rocks, and
decaying organic matter.

9. Soil can be characterized by
its profile, texture, color,
consistency, and acidity.

10. It is described
according to
its physical
and chemical
properties.
SOIL HORIZONS

11. Gritty – contains much sand
Smooth – contains more silt
Sticky – contains more clay
SOIL TEXTURE

12. Sand particles – measures up to 2
mm
Clay particles – particles are
smaller than 0.002 mm
Silt particles – particles measure
between 0.05 to 0.002 mm

13. Loam contains a good proportion
of these three soil types.
Particles that are bigger than 2
mm are no longer considered as
soil materials - classified as stone
or gravel.

14. The kind of elements or minerals
which are present in the soil gives
its characteristic color.

15. The ease or difficulty of breaking
the soil apart gives its consistency.
loose – cannot hold a single soil
structure
firm or extremely firm – if you
cannot break it apart by bare
hands.

16. It influences the kind of plants
which can grow in it.
The acidity of the soil is
affected by the water it
absorbs, natural and man-
made processes.

17. Land pollution is
the destruction and
contamination of
the land through
the direct and
indirect actions of
humans.
The pollution
results in changes to
the land, such as

18. Mining

19. The mining
process can lead
to the creation of
large open spaces
beneath the
surface of the
earth that can
lead to soil
erosion.

20. The use of
harmful
pesticides and
insecticides in
farming to
protect crops -
these chemicals
can cause the
land to become
barren.

21. The garbage
found at
landfills is
filled with
toxins that
eventually
seep into the
earth.

22. Litter makes it difficult for
plants and other producers in
the food web to create
nutrients.
Animals can die if they
mistakenly eat plastic.

23. A massive landfill
at Payatas,
Quezon City was
the site of a land
pollution tragedy
in 2000.
Heavy rains
caused a trash
landslide, killing
218 people.

24. The chemical improperly disposed
of on the land could end up in the
ground water. The process is known
as leaching. It can occur on farms,
industrial sites, and landfills.

25. Effects of Land Pollution to Human
Some of the potential consequences
include birth defects, the development
of breathing disorders, skin diseases,
and cancer.
Land pollution has also been linked to
developmental deficits in children -
child’s cognitive development.
