Discover the four major earth systems and it's interaction with one another.

1. Earth and
Earth’s
Systems

2. WHAT MAKES EARTH
SUITABLE FOR LIFE?
UNIQUENESS OF EARTH

3. EARTH’S UNIQUE
FEATURES
• right distance from
the Sun
• presence of an
atmosphere
• right amount of
gravity
• presence of
magnetosphere
• presence of
molecular oxygen
• presence of liquid
water
• generation of
internal heat
• energy from
lightning

4. RIGHT DISTANCE FROM THE SUN

5. PRESENCE OF AN ATMOSPHERE

6. RIGHT AMOUNT OF GRAVITY
• When gravity is
weak, Earth will
lose its
atmosphere.
• When gravity is
too strong, Earth
will be bombarded
with meteors.

8. PRESENCE OF MOLECULAR
OXYGEN

9. PRESENCE OF LIQUID WATER

10. GENERATION OF INTERNAL HEAT

11. ENERGY FROM LIGHTNING

12. Earth as a SYSTEM

13. A closed system is a system
in which there is only an
exchange of heat or energy
and no exchange of matter.
The Earth System is
essentially a
CLOSED SYSTEM.

14. The Earth receives energy
from the Sun and returns
some of this energy to space.
EARTH

15. • also known as GEOSCIENCE
• the study of the Earth and its processes,
encompassing its physical, chemical, and
biological systems
EARTH SCIENCE

16. • SCALE
• ENERGY
• CYCLES
MAJOR THEMES

17. • processes in the Earth system:
SCALE
• Length scale (microns to thousands of
kilometers)
• Time scales (milliseconds to millions of
years)

18. • External Source: SUN
• Internal Source:
ENERGY
• Radioactive decay
• Gravitational Energy

19. • Material in the Earth system is
continually recycled in numerous
overlapping cycles.
CYCLES

24. EARTH
SYSTEMS
Biosphere Hydrosphere
Geosphere Atmosphere

25. • It includes all life forms on
Earth
• 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.
Biosphere

26. • James Lovelock used the
“Daisy World Model” to
illustrate how the biosphere
is capable of regulating its
environment.
Biosphere
The Albedo Effect

27. • Dynamic mass of water
that is continuously on
the move
• About 70% of the Earth is
covered with liquid water
(hydrosphere) and much
of it is in the form of
ocean water
Hydrosphere

28. • Only 3% of Earth’s water
is fresh: two-thirds are in
the form of ice, and the
remaining one-third is
present in streams, lakes,
and groundwater.
Hydrosphere

30. • is the thin gaseous layer
that envelopes the
lithosphere
• The present atmosphere
is composed of: 78%
nitrogen (N), 21%
oxygen (O), 0.9% argon,
and trace amount of
other gases.
Atmosphere

31. One of the most important
processes by which the heat on
the Earth’s surface is
redistributed is through
atmospheric circulation.

32. • the solid Earth
• extends from the surface to
the center
Geosphere

35. Crust • It’s the light and
very thin layer
outer skin of the
Earth.
• The outermost
layer where energy
and mineral
resources are
derived.

37. Mantle
• Less dense layer
• Made up of silicate
rocks, mostly
made of the
elements silicon,
oxygen, iron and
magnesium.

38. Core
• Denser layer
• The Earth’s
magnetic field
strengthens the
idea that the
Earth’s outer core
is molten/liquid.

40. Using a sheet of Oslo paper, create a colorful and creative poster that
shows at least one real-world event demonstrating the interaction of
two or more of Earth’s systems (geosphere, hydrosphere, atmosphere,
and biosphere). Clearly label the parts of your drawing that represent
each Earth system, and make sure your illustration is neat, organized,
and scientifically accurate. Examples of events you may illustrate
include volcanic eruptions, typhoons, deforestation, or tsunamis. On
the back side of the Oslo paper, write a short explanation (minimum of
5 sentences) describing the event, identifying which Earth systems are
involved, and explaining how they interact.
