ENVIRONMENT

representative of physical components of the earth where in man is an important factor affecting the environment.

ENVIRONMENT

surrounding external conditions influencing development or growth of people, animal, and plants

PHYSICAL

ELEMENTS OF ENVIRONMENT

are as space, landforms, water bodies, climate soils, rocks and minerals.

determine the variable character of the human habitat, its opportunities as well as limitations.

BIOLOGICAL

ELEMENTS OF ENVIRONMENT

such as plants, animals, microorganisms and men constitute the biosphere

CULTURAL

ELEMENTS OF ENVIRONMENT

economic, social, and political elements are essentially manmade features, which make cultural milliue.

ATMOSPHERE

SCOPE

- sustain life on earth

- save earth from environment of outer space

- absorbs cosmic rays and electromagnetic radiation from the sun

- transmit only uv rays,near infrared radiation and radio waves

- composed of N, O, Ar, and CO2

HYDROSPHERE

SCOPE

- 97% of earth's water supplies is in the ocean

- 2% locked in polar icecaps and glaciers

- 1% human consumption

LITHOSPHERE

SCOPE

- outer mantle of the solid earth

- consists of minerals occurring in earth's crusts and soil

ex: minerals,organic matters,air, and water

SCIENCE

Systematized body of knowledge based on nature and facts of life.

a strategy for understanding and explaining the social and natural world that emphasizes the use of statements that can be examined to see whether they are wrong.

NATURAL

SOCIAL

FORMAL

BRANCHES OF SCIENCE

ENVIRONMENTAL SCIENCE

The science of Environment studies is a multi-disciplinary science because it comprises various branches of studies like chemistry, physics, medical science, life science, agriculture, public health, sanitary engineering etc.

It is the science of physical phenomena in the environment. It studies of the sources, reactions, transport, effect, and fate of physical and biological species in the air, water and soil and the effect of from human activity upon these.

ENVIRONMENTALISM

A heterogeneous worldwide social and political movement, which champions the preservation, sustainable management, and restoration of the natural environment in an endeavor to fulfill human wants, including spiritual and social needs, as well as for its own sake.

OBJECTIVES OF ENVIRONMENTALISM

Nature Worship,

A commitment to maintain the health of the natural system,

Identification of humanity as part of and not detached to the ecosystem.

BARRY COMMONER

THE PROPER USE OF SCIENCE IS NOT TO CONQUER NATURE BUT TO LIVE IN IT.

STEPS OF SCIENTIFIC METHOD

OBSERVATION

FORMULATION OF HYPOTHESIS

HYPOTHESIS TESTING

DATA GATHERING

DATA INTERPRETATION

CONCLUSION

MULTISPECTRAL SCANNER

A scanning system used to collect data over a variety of different wavelength ranges.

LANDSAT 4

Monitoring of Earth's environment for more than four decades, providing detailed imagery of some of our planet's most precious ecosystems such as forests, coastlines, glaciers, volcanoes, and oceans.

DIFFERENTIAL ABSORPTION LIDAR

Is used to detect concentrations of gases within a transect in the atmosphere. Lidar is an acronym for light detection and ranging, and the technique is used for measuring physical characteristics of the atmosphere.

LIDAR

LIGHT DETECTION AND RANGING

LASER FLUOROSENSOR

Airborne surveillance and monitoring of oil spills, and the exploration of marine petroleum resources.

GEOGRAPHIC INFORMATION SYSTEM

Is a computer system for capturing, storing, checking, and displaying data related to positions on Earth's surface, GIS can help individuals and organizations better understand spatial patterns and relationships.

NATURAL RESOURCES

Are materials from the Earth that are used to support life and meet people’s needs.

are the raw materials for making products that we use every day.

RENEWABLE AND NON-RENEWABLE

TWO TYPES OF NATURAL RESOURCES

RENEWABLE RESOURCES

Can be renewed or replenished in reasonable amount of time naturally. (Years or a human lifespan)

Generated from natural resources. (Sun, wind, rain, tides, vegetation).

SOLAR ENERGY

The sun’s light contains energy in the form of electromagnetic waves.

Usually, when light hits an object the energy turns into heat, like the warmth felt while sitting in the sun. But when light hits certain materials, like silicon, the energy turns into an electrical current instead, which can then be harnessed for power.

EINSTEIN’S PHOTOELECTRIC EFFECT

light can act like a particle, as well as a wave.

CALATAGAN SOLAR POWER PLANT IN BATANGAS

EXAMPLE OF SOLAR ENERGY

HYDROELECTRIC ENERGY

use falling water from a dam to turn the turbine of a generator. The generator then produces electricity.

ANGAT HYDROELECTRIC PLANT IN BULACAN

EXAMPLE OF HYDROELECTRIC ENERGY

GEOTHERMAL ENERGY

Deep inside the Earth lies hot water and steam that can be used to heat homes and businesses and generate electricity cleanly and efficiently. The steam is used to drive turbines of a generator and the generator produces electricity.

EARTH

GEO

HEAT

THERME

WIND ENERGY

The energy of the wind is transferred to the turbines of the generator and the generator produces electricity.

use the momentum of moving air to quietly turn large blades that are attached to the shaft of an efficient electric generator.

BIOMASS ENERGY

matter usually thought of as garbage. This matter includes things like leaves, tree branches, leftover crops, wood chips, and bark. It can even include animal manure and old tires.

SAN CARLOS BIOMASS POWER PLANT IN NEGROS ORIENTAL

EXAMPLE OF BIOMASS ENERGY

NON-RENEWABLE RESOURCES

Is one that has specific conditions that made them (like fossilized plant matter converting into coal) and can take many generations to reproduce.

Sometimes the conditions are not likely to occur again so they are limited in supply and once used cannot be re-generated within a short span of time.

NATURAL GAS, OIL, COAL

Non-renewable sources exist in the form of;

COAL ENERGY

the product of millions of years of pressure on organic matter from plants buried underground.

CRUDE OIL

referred to as Liquid Petroleum.

OIL ENERGY

It is used for gasoline, heating oil, and diesel fuel.

NATURAL GAS

Consumers use it as cooking fuel, to heat houses, and sometimes as vehicle fuel.

NUCLEAR ENERGY

makes use of Uranium-235, a radioactive chemical naturally found in the earth.

URANIUM 235

This radioactive substance undergoes decay and, in the process, releases a great deal of heat.

SUSTAINABILITY

the practice of using natural resources responsibly today, so they are available for future generations tomorrow.
