B. Explore
The teacher will present a video clip on four sub-systems of Earth and then group the
learners into 4. Upon seeing the four sub-systems, ask them to present a role play on how to
preserve the beauty and the role of the sub-systems on Earth.
Group 1 – Atmosphere
Group 3 – Hydrosphere
Group 2 – Geosphere
Group 4 – Biosphere

C. Explain
First Sub-system: Atmosphere
The word atmosphere comes from the Greek roots atmos which means gas, and sphaira
which means globe or ball. The atmosphere makes up of all the gases on Earth. It
extends
outward about 10 000 km from the surface of the Earth.
Second Subsystem: Geosphere
The geosphere is considered that portion of the Earth system that includes the Earth's
interior, rocks and minerals, landforms and the processes that shape the Earth's surface. The Earth
itself is not a perfect sphere but an oblate spheroid, with a radius of 6,357 kilometers (km) from the
Earth's center to the North Pole and 6,378 km from the center to the Equator.
Third Subsystem: Hydrosphere
The hydrosphere is the sum of all water on Earth and the water cycle that distributes it
around the planet. Earth is unique in the solar system for its abundant surface waters. Our orbital
distance from the sun, in addition to our unique atmosphere, gives Earth the right temperature in
our middle-aged solar system to have water as a liquid, and lots of it. It's because of the hydrosphere
that life flourishes on Earth.
Fourth Subsystem: Biosphere
The biosphere contains the entirety of Earth’s living things. It is sometimes referred to as the
“zone of life”. From a geophysical standpoint, biosphere is the global ecological system integrating all
living things and their relationship including their interactions with the elements of the lithosphere,
hydrosphere and atmosphere. The biosphere is divided into biomes. Biomes are the world’s major
communities. They are classified according to the predominant vegetation characterized by
adaptations of organisms to that particular climate.

5. The Earth system is considered __________________.
a. a closed system
c. an isolated system
b. an open system
d. none of the above
VI. Assignment
Direction: In your own words, explain in 3-5 sentences how the reflected subsystems are interacting.
1. Water is necessary for the transport of nutrients and waste products in organisms like plants,
animals and human.
2. Typhoon forms when there is an LPA which intensify as it absorbs the water vapor in the Pacific
Ocean which in turn causes landslide and destruction of organisms.
3. Global warming heats up the Pacific Ocean causing the glaciers to melt and adding more water to
the ocean.
