Learning Competency
At the end of this lesson, the given enabling competency
should be met by the students.
Recognize that soil, water, rocks, coal, and other fossil
fuels are Earth materials that people use as resources.
Learning Objectives
At the end of this lesson, the learner should be able to
do the following:
● Identify the different natural resources that sustain
life on Earth.
● Explain how the natural resources sustain life.
The Philippines is
rich in natural
resources because
of its strategic
location and it
being a tropical
country.

● Natural resources are
materials or substances
such as minerals, forests,
water, and fertile lands that
occur in nature and can be
used for economic gain.
The Philippines has rich natural
resources like extensive coastlines.

Earth’s Natural Resources
● Water
○ It is a major resource that
every organism needs in
order to survive.
○ Earth’s surface is mainly
composed of water (71%).
■ 97% saltwater
■ 3% freshwater
The distribution of water in the
Earth’s hydrosphere

Earth’s Natural Resources
● Water
○ Freshwater is mostly
inaccessible as ice and
little remains as
groundwater.
○ Saltwater serves as a
sanctuary for different
marine life and provides a
wide variety of seafood.
Fishing is one of our staple
sources of livelihood.

Earth’s Natural Resources
● Water
○ Water can be used
for consumption
and for irrigation in
agriculture.
Providing crops with water is
referred to as irrigation.

● Soil
○ It is usually the
topmost layer of
Earth.
○ It provides minerals
and physical support
for plants.
Soil is needed by plants for
their growth.
Learn about It
Earth’s Natural Resources
● Soil
○ Soil comes from the
weathered parts of rocks,
which are transported and
deposited elsewhere.
○ Weathering is the
breaking down of rocks
into smaller particles.
Erosion of rocks

Earth’s Natural Resources
● Soil
○ The process of soil formation involves the interaction of
five factors:
■ parent material
■ living organisms
■ climate through wind speeds or temperature
■ topography
■ time

Earth’s Natural Resources
● Minerals
○ Minerals are solid
elements that
naturally occur
underground.
○ They may look like
ordinary rocks or
magnificent crystals.
Philippines is one of the biggest sources
of gold (left), copper (right), nickel, iron,
and manganese.

Earth’s Natural Resources
● Minerals
○ Metallic minerals are
those with a high
specific gravity and
metallic luster.
○ Nonmetallic minerals
are those that lack
metallic properties.
Talc (left) and marble crystals (right)
are examples of nonmetallic minerals.

● Life Forms
○ These are the different
living organisms that
inhabit an environment.
○ The two broad categories
of life forms are flora
(plants) and fauna
(animals).
Tarsier (left) and Philippine
pitcher plant (right) are examples
of endemic species in the
Philippines.

● Energy
○ Fossil fuels come from
the remains of plants
and animals that lived
millions of years ago.
● coal
● natural gas
Lignite, a type of coal found in
nature
Learn about It
Earth’s Natural Resources
● Energy
○ Fossil fuels
■ Coal is a black rock formed
from plant remains.
■ Natural gas is a naturally
occurring gas mixture
consisting of methane.
Petroleum in gas stations is
an example of a natural gas.

Earth’s Natural Resources
● Energy
○ Geothermal energy is
energy harnessed from
volcanic vents and hot
springs.
○ The Philippines is regarded
as the third top producer of
geothermal energy.

● Energy
○ Hydroelectric power
plants harness energy
from the flowing water
from dams, rivers, and
waterfalls.
Ambuklao dam in Benguet is the major
hydroelectric power plant in the
country.

Earth’s Natural Resources
● Energy
○ Biofuel is an energy
resource from agriculture
in the form of produce or
wastes like animal
excrements, microalgae,
and the unused parts of
crops, such as corn,
wheat, and potatoes.
Dried corn husks can be used to
produce biofuel.

Earth’s Natural Resources
● Energy
○ Nuclear energy is harnessed
when an atom is split (nuclear
fission) or when atoms collide
(nuclear fusion).
○ It can provide the most energy
among all energy resources.

● Energy
○ The Philippines almost had
a nuclear power plant but
construction was halted
due to the following:
■ location: near a dormant
volcano
■ quality: unsuitable
construction materials

Key Points
● Materials coming from the environment used to sustain life are called natural
resources.
● Life forms are the different living organisms interacting with each other. The
two broad categories of life forms are flora (plants) and fauna (animals).
● The energy resources of the Philippines mostly come from geothermal
energy, hydroelectric energy, and fossil fuel combustion.
● Resources that can be replaced in a short period of time are called renewable
resources. Nonrenewable resources are those which cannot be replaced or
replenished immediately.
Check Your Understanding
Identify the natural resource described in each of the
following statements.
1. This particular energy resource is harnessed when an atom is split (nuclear
fission) or when atoms collide (nuclear fusion).
2. These rock-like resources are natural elements occurring underground.
3. This resource is the result of weathering, transport, and deposition of rocks.
4. This is a major resource needed by all organisms for their growth,
development and survival. This is particularly important in the process of
photosynthesis.
5. This involves all the flora and fauna found within the country.
