CHAPTER 2 : UNDERSTANDING THE NATURAL and MAN-MADE ENVIRONMENTS Flashcards
Sustainable
Development
Economy, Environment, Society
Responsible Human
Interaction with the Environment
learn, value, protect
different components of the
environment
lithosphere, hydrosphere,
atmosphere, and biosphere
Learn about the different components of the
environment, including the lithosphere, hydrosphere,
atmosphere, and biosphere. This includes understanding
the interactions between living and nonliving things.
Learn
Recognize the vital role of the environment in
sustaining life. Appreciate the interconnectedness of all living things and their dependence on natural resources.
Values
Practice sustainable resource management, minimizing
waste, and reducing pollution to protect the
environment for future generations. Support initiatives
promoting conservation and responsible use of natural
resources.

The Earth’s solid outer layer,
including rocks, soil, and
minerals. It provides a foundation
for life and contains valuable
resources such as minerals and
fossil fuels.
lithosphere
The top layer of the Earth’s
crust, composed of
weathered rocks, organic
matter, and microorganisms.
soil
The top layer of the Earth’s
crust, composed of
weathered rocks, organic
matter, and microorganisms.
soil
Naturally occurring solid
substances with a definite
chemical composition and
crystalline structure, found within
the lithosphere.
minerals
It encompasses all the water on Earth, including oceans,
lakes, rivers, groundwater, and ice. It is a critical component of the
environment, supporting all life, regulating climate, and providing a habitat
for a diverse array of organisms.
Hydrosphere
The layer of gases surrounding the Earth, primarily composed of nitrogen
and oxygen. It protects us from harmful radiation, moderates temperatures,
and allows for weather patterns.
Atmosphere
The parts of the Earth where life exists, including all living organisms,
plants, animals, and microorganisms. It encompasses all the interactions
between living things and their environments.
Biosphere
2 types of environment
Natural Environments
Man-made Environments
___ are untouched by
human activity, such as forests, deserts,
oceans, and mountains.
Natural Environments
___ environments are areas created
or significantly altered by humans, such as
cities, farms, and industrial parks.
Man-made Environments
___ are made up of cells,
require energy, grow and develop,
reproduce, and respond to stimuli.
Living things
scientific name of living things
Biotic
___ things are not made up of cells, do
not require energy, do not grow and develop, do not reproduce, and do not respond to stimuli.
Examples include water, light, soil, rocks, and
air.
Nonliving
scientific name for nonliving
Abiotic
characteristics of living things
Living things exist and are alive and are made of microscopic structures called cells.
characteristics of nonliving things
▪ Nonliving things are not alive.
▪ They do not possess life.
▪ They do not fall into any cycle of
birth, growth or death. They are
created and destroyed by external
forces.
