7.  the condition that distinguishes
organisms from inorganic objects and dead
organisms, being manifested by growth
through metabolism, reproduction, and the
power of adaptation to environment through
changes originating internally.

Life on earth
➢ Inability to recognize the full
consequence of his or her actions; and
➢ Lack of appreciation of how truly
unique the Earth is.

15. Being in the Goldilocks Zone indicates that due to the
distance of Earth from the sun, the amount of heat and
solar energy received is just enough to make the
temperature of Earth neither too hot nor too cold. As we
all know, water evaporates if it is subjected to a very hot
temperature and gets freezes if subjected to a very cold
temperature. The capability of early Earth to
sustain liquid water dramatically
increased the possibility of life.

18. Unique Features of Earth that
are important for life
1. Surface liquid water
2. Atmospheric oxygen
3. Plate tectonics
4. Climate stability
•(5) Appropriate
distance from the Sun
•(6) Moderate global
temperature (15o C)
•(7) Minerals and
Energy resources

19. 1. Presence of Water
• Earth is the only planet covered
mainly with 75% surface water).
Water is essential for life. Almost
all living things need water in order
to survive.

20. 2. Atmospheric oxygen
• Earth’s atmospheric composition is suitable
for life to exist. The different gases present on
Earth with their corresponding percentage is
presented below:

22. 3. Plate Tectonics
• Earth has Nickel-Iron core, which produces
its magnetic field. Materials on Earth including
its water and atmospheric gasses are contained
inside because of magnetic field. Materials
also from the inside of the Earth is circulated to
its surface through volcanic activity, geosphere
movement like earthquake or through hot
spots and plate boundaries

27. Indeed Earth is a special
planet. It has unique
characteristics that enables
to sustain and support life
and make it habitable for
different life forms.

28. All of these characteristics such as the
right distance from the Sun, it is
protected from harmful solar radiation
by its magnetic field, it is kept warm by
an insulating atmosphere, and it has
the right chemical ingredients for life,
including water and carbon is natural
to Earth.

29. The processes that shape the Earth and
its environment constantly cycle elements
through the planet.
This cycling sustains life and leads to the
formation of the mineral and energy
resources that are the foundation of
modern technological society today.

30. Application
With the knowledge you have learned, how
would you maintain the different factors that
makes the Earth habitable?
Create a campaign ad (digital or
using available materials) on how to
sustain Earth as a habitable planet. Upload it on
social media or post it on areas within your
community so you educate others and convince
them to do the same.
