Earth Subsystem

Lesson 2: Earth’s Subsystem

Teresita B. Moreno [e-mail]

Competencies:

1. explain that the Earth consists of four subsystems,

across whose boundaries matter and energy flow

2. trace the flow of matter and energy in the subsystem
3.apply the 5 Rs in daily life and improve ways of

taking care Earth’s natural resources

Guide Questions:

1. What are the components

of the terrarium

2. Give the functions of each

components in the
terrarium that enable life
to sustain on it.

3. How can you compare

the terrarium to an Earth
system?

Pre-Assessment

Multiple Choice

What is the reason why the atmosphere is essential to life?

• It only provides blanket that covers the earths surface.

• It solely gives oxygen and carbon dioxide.

• It regulates the earth's temperature over a period time.

• It provides the gases essential to life and for organisms to perform bodily processes.

Multiple Choice

How is biosphere different from the other subsystems?

• It is dependent only on hydrophere and geosphere.

• It is composed of all living organisms.

• It is composed of soil, rocks and minerals.

• It provides air which supports respiratory processes of living organisms.

Multiple Choice

Why are subsystems interconnected to each other?

• They have the same composition and characteristics.

• They can alter the flow of energy in a minimal amount.

• They work together to influence the climate, trigger geological processes, and affect life all over the Earth.

• They are all compost of living things that influence the flow of matters.

Multiple Choice

What subsystem interacts when a rice plant draws water and nutrients from the soil?

• Atmosphere, Biosphere and Geosphere

• Biosphere, Hydrosphere and Geosphere

• Geosphere, Atmosphere and Biosphere

• Hydrosphere, Atmosphere and Geopshere

Multiple Choice

Analyze the ecological phenomena given below. Which of the given situations shows the interaction between hydropshere and atmosphere?

• Evaporating water

• Pouring rain

• Flowing stream

• Drinking water

Word Hunt

Identify words
associated to the
different Earht’s

subsystem

Draw

Identify words associated to the different Earth's subsystem.

Guide Questions:

1. How are the words associated to each other?

2. In which subsystem are the words

connected?

3.How can you say that the highlighted words

are related to subsystems?

Four Subsystems

THE EARTH SUBSYSTEMS

Biosphere

Hydrosphere

Geosphere

Atmosphere

Next

1. Atmosphere

atmos - gas
sphaira -
global or ball

The atmosphere is the thin
gaseous layer that envelopes
the lithosphere.

Atmosphere

The present atmosphere is composed of 78% nitrogen (N),
21% oxygen (O2), 0.9% argon, and trace amount of other
gases.

2. Geosphere

geo - ground
- rocks
- minerals

3. Hydropshere

hydro - water
3 phases (solid, liquid , gas)
cryosphere - frozen part

Dynamic mass of water that is
continuously on the move

Hydrosphere

4. Biosphere

It covers all ecosystems—from the soil to the
rainforest, from mangroves to coral reefs,
and from the plankton-rich ocean surface to the
deep sea.

What will happen if one of them is missing?

We are Connected!

“When one tugs at a
single thing in nature,
he finds it attached to
the rest of the world.”

below and give the
subsystem it
represents.
