20. Remember these terms…
1. Atmosphere - The body of gases that surrounds our planet.
2. Biosphere – The sphere that includes all living organisms.
3. Geosphere – The solid, inorganic Earth, including Earth’s
surface and layers of its interior.
4. Hydrosphere - All of the water in the Earth system, including
water in the oceans, rivers, lakes, air, and below Earth’s surface.
5. Cryosphere - The places where water is in its solid form, frozen
into ice or snow.
6. System - A set of connected things or parts forming a complex
whole, in particular.

21. Activity 1: Frayer Model Construction
• In groups, construct a Frayer Model of the
Earth’s subsystems using the materials
provided.
• After 10 minutes, presentation of output will
follow.
• While the presentation is going on, members
should take down important terms for future
use.

22. Presentation of output…

23. Activity 2. Identifying relationships between and
among the subsystems.

24. • How is the
atmosphere related or
connected with the
hydrosphere?
• Is there a relationship
between the
geosphere and the
biosphere (trees)?
• Could you identify
some other
relationships that exist
between two
subsystems?
How do we identify
relationships?

25. • Geosphere:
The ground could
have been very
permeable,
preventing
moisture from
being retained in
the upper part of
the soil profile.

26. • Hydrosphere:
• The area could
have been
prone to fire
due to lack of
precipitation.

27. • Atmosphere:
• The fire could
have started
due to a
lightning strike.

28. • Biosphere:
• Dead wood,
leaves and
needles may
have enhanced
the ability of the
fire to start and
spread.

29. Relevance to Geosphere
1. Heat from the fire
causes rocks to crack
(therefore enhancing
weathering).
2. Soil erosion is also
enhanced by the removal
of vegetation.
3. Ash particles from the
fire alter the chemistry of
the soil.

30. Relevance to Atmosphere
1. Smoke and ash particles
are carried by wind to other
areas.
2. Increased precipitation
elsewhere is enhanced due to
the ash particles acting as
nucleation centers for water
droplets.
3. Gaseous pollutants such as
carbon dioxide (CO2) are
produced during the burning of
the vegetation and carried into
the air by the wind.

31. Relevance to Hydrosphere
1. Heat from the fire
further removes moisture
from the air, soil, and
vegetation through the
process of evaporation.
2. Increased siltation of
streams due to enhanced
erosion (particles are then
deposited as sediment).

32. Relevance to Biosphere
1. Immediate destruction of habitat in burn
area.
2. Smoke in the air may have coats the
lungs of animals, including people, and
affects their ability to breathe.
3. Ash particles in water clogs the gills of
fish and other aquatic organisms.
4. On the positive side, nutrients released
from ash from the fire can, on the long term,
benefit future plant communities.
5. Also, seeds of some plants may require
that their outer shells be burned before they
can germinate (so the forest fire benefits
these plants).

33. It’s your turn now.
• Identify the relationship that may exist between
and among the earth subsystems from the
following pictures/events.
• Write as many relationships as you can before
the time runs out.
• Each group shall be given a picture to focus
on.
• Presentation of output shall follow immediately.

34. Group 1
1. An erupting
volcano has an
effect on the
following:
Geosphere
Atmosphere
Hydrosphere
Biosphere

35. Group 2
2. A strong
typhoon has an
effect on the
following:
Geosphere
Atmosphere
Hydrosphere
Biosphere

36. Group 3
3. A tsunami
caused by a
strong earthquake
has an effect on
the following:
Geosphere
Atmosphere
Hydrosphere
Biosphere

37. Group 4
3. Grassfire
caused by
lightning has an
effect on the
following:
Geosphere
Atmosphere
Hydrosphere
Biosphere

38. Presentation of Output per Group…

39. To deepen your knowledge, do the next task in a
¼ sheet of paper!

40. Classify each of the words below with the right
sphere of the Earth.
1. Atmosphere: _________, _________
2. Biosphere: _________, _________,
_________
3. Geosphere: _________, _________
4. Hydrosphere: _________, _________,
_________
Stratosphere Mountain Alligator Lake Crust
Troposphere Sunflower Frog River Ocean

41. Assignment: “Connect the Spheres: Earth’s
Systems Interactions”
• Write down 5 observations from your
surroundings.
• Write the earth subsystems in a bond paper in a
way that one subsystem stays in one corner of the
paper.
• Circle the system the observation belongs with.
• Draw arrows to make connections between that
system/observation and the other systems. Make
as many as you can!
• Along each arrow, write details about what that
interaction is.
• An example is given on the next slide.

42. Example…
Observation: It rains every afternoon.
Hydrosphere Atmosphere
Geosphere Biosphere
Wets the land
Provides water
to living
organisms for
survival
More water reserves that
may evaporate during
daytime

43. That’s all for today…
