CHAPTER 5 : NATURAL RESOURCES Flashcards
___ are components that exist in the world
without the input of humans. These are diverse ranging from
renewable to nonrenewable, living to nonliving, as well as
tangible to intangible resources
Natural resources
Natural resources are essential to our ___ and that of all other
living organisms.
survival
What causes the high demand for natural resources around the world
rapid depletion
We need natural resources for our ___,
___, ___, and ___.
survival, growth, development, progress
What are the things that can be transformed to produce benefits (Chan, 2016)
materials, water, energy, minerals, and others
classification of natural resources
renewable and
nonrenewable resources
solar energy, air, wind, water, tides, flowing, soil, and plants are classification of what resources
renewable
fossil fuels, non metallic minerals, and metallic minerals are components of what classification of resources
nonrenewable
•Can be used repeatedly and does not run out
because it
is naturally replaced
•resource that can replenish itself at a similar
rate to its
use by people.
Renewable Natural Resources
•are those whose exploitation eventually reaches a
level beyond which regeneration will become
impossible.
•Such is the case with the clear-cutting of tropical
forests (OECD, 2001a).
Conditionally renewable resources
Since earth formed, the ___ has produced
energy in the form of heat and light. It is
considered unlimited
sun
Radiation from the sun is converted into
electricity with the use of ___
photovoltaic cells
Major solar farms in the Philippines can be
found in ___, ___, ___, and ___
Cavite, Pampanga, Ilocos Norte, and
Cagayan de Oro
It generates electricity by turning wind turbines
that can supply power and it can even be stored in
the power grid.
Wind Energy
Since earth formed, the sun has produced
energy in the form of heat and light. It is
considered unlimited
Solar energy
What is the country’s oldest wind
farm and the first power-generating wind farm in
Southeast Asia
The Bangui Wind Farm in Ilocos Norte at the north-
west tip of Luzon island
The mechanical energy creates energy that can
be captured and turned into ___.
electricity
Water is
constantly renewed by the
water cycle
___ is one of the oldest renewable
resources and has been used for thousands of
years
Hydropower
___use the flow of rivers
and streams to turn a turbine to power a
generator, releasing electricity.
Hydroelectric power plants
It comes from the heat generated deep within
Earth’s core.
Geothermal Energy
___ can be found at tectonic
plate boundaries near volcanic activity or deep
underground.
Geothermal reservoirs
Geothermal energy can be harnessed by ___ to pump hot
water or steam to a power plant.
drilling wells
Geothermal energy is used for
heating and
electricity
•It refers to organic material from plants or animals including wood, sewage, and ethanol
(which comes from corn or other plants).
•This organic material has absorbed energy from
the Sun. This energy is, in turn, released as heat
energy when burned.
Biomass
A natural substance that is not replenished with
the speed at which it is consumed.
Non-Renewable Resources
It was formed within the Earth from
decomposing plants and other organisms,
buried beneath layers of sediment and
rock, over millions of years to become
carbon-rich deposits.
Fossil fuels
Fossil fuels are forms of stored ___
solar energy
When fossil fuels are burned, they release
carbon dioxide and other greenhouse gases
the primary contributors to
global warming and climate change (Nunez,
2019).
carbon dioxide and other greenhouse gases
___ is a liquid fossil fuel.
Oil
___ is a black or brownish rock.
Coal
We burn coal to
create ___
energy
How many land resources are available to us
10%
How many of natural gas are available to us
15%
How many animal resources are available to us
25%
How many forest resources are available to us
30%
How many wind energy are available to us
15%
How many solar energy are available to us
5%
___ are naturally occurring inorganic
substances found under varying conditions
and in different types of geological
environments.
Minerals
Minerals have a crystalline structure and come
with a definite ___
chemical composition.
Minerals are divided into two types, namely:
___ and ___ minerals.
metallic and nonmetallic
•are composed of one or more metallic elements;
•obtained from ores
Metallic minerals
•do not contain any metal elements instead they consist
of chemical elements that usually don’t feature the
properties or characteristics of metals. (BYJU’s, n.d.)
•procured from industrial rocks and minerals
Nonmetallic minerals
Examples of metallic minerals
Copper, tin, iron, manganese, gold,
etc.
Examples of nonmetallic minerals
Carbon, gypsum, potash, precious
stones, boron, sulfur, mica, quartz, dolomite,
diamond etc.
