The document discusses the different spheres or layers of the Earth. It begins by describing the Earth and its color compared to other planets. It then discusses the four subsystems that make up Earth and flow of matter and energy between them. It identifies the layers of the Earth and differentiates between them. Finally, it discusses natural waters and the water cycle.

What is the Earth’s Atmosphere?

32. LAYERS OF THE ATMOSPHERE

34. Troubled = Troposphere
Super = Stratosphere
Man = Mesosphere
Tricked = Thermosphere
Ellen = Exosphere

35. TROPOSPHERE
◍Troposphere is where the weather forms;
commercial airplanes also fly on this layer. The
air is very unstable on this layer that’s why we
sometimes experience a bumpy ride which we
call turbulence. The highest peak in the world
which is the Mt. Everest also seats in this layer.

36. TROPOSPHERE
◍Consider to be the densest among the other
layers.
◍Most jets and planes would fly slightly above
the troposphere to avoid turbulent weather.
◍Tropopause – thin buffer zone reaching the
next layer above the troposphere

37. STRATOSPHERE
◍Stratosphere is where a spy jet flies because
the air is very stable. Ozone layer is also found
here.

38. STRATOSPHERE
◍The air in this layer has strong, steady
horizontal winds which is advantageous to long
distance flights.
◍Ozone layer - plays a very important role in
absorbing the ultraviolet radiation from the sun.
◍Stratopause- thin buffer zone exists before the
next layer above the stratosphere.

39. MESOSPHERE
◍Mesosphere is where meteors and
other rock fragments burn up.

40. MESOSPHERE
◍The temperature reaches minimum of -90°C
◍Considered to be the coldest layer.
◍Carbon dioxide tends to cool the layer by
radiating heat into space.
◍Important in protecting earth from planetary
debris
◍Mesopause – thin buffer zone above the
mesosphere

41. THERMOSPHERE
◍Thermosphere is where auroras are found.
Sun's energy is so strong at this level, that it
breaks apart molecules. So there ends up being
electrons floating around and molecules which
have lost or gained electrons that is why we
have radio signals because of this layer.

42. THERMOSPHERE
◍Hottest layer because of its absorption of
highly energetic solar heat.
◍Can rise higher, even reaching beyond 1000°C
◍Ionosphere- lower part of the thermosphere,
where particles of oxygen and nitrogen are
electrically charged by the solar wind.

43. THERMOSPHERE
◍Aurora- the specular display of colorful
lights in the sky
Aurora borealis or northern lights
- witnessed in the northern region
Aurora Australis or southern lights
-seen in the southern regions
Thermopause- serves as the buffer zone which
separates the thermosphere from space.

44. Aurora borealis or Northern lights
- Aurora displays occur
when charged particles from
the sun interact with gases
in the earth’s atmosphere.
Auroras are seen only in the
high latitudes of both
hemispheres because the
earth’s magnetic field draws
solar particles into the polar
regions

45. EXOSPHERE
◍Exosphere, the outermost layer and
extends through space. It is where the
satellites are stationed.

46. What do you think is the
basis for the division of
our atmosphere?
In what layers of the
atmosphere does the
temperature increase
with height?

47. In the troposphere, why do you
think temperature decrease as
altitude increases?
Why do you think the
temperature in the
stratosphere increases
with height?

48. In the mesosphere,
temperature decreases
as height increases, what
do you think causes this
temperature variation?
Temperature increases
with altitude in the
thermosphere. Give a
possible explanation.

49. What are the
relationship of altitude
and temperature
between each layer?

50. Layers of the Atmosphere Relationship between Altitude and
Temperature
Troposphere Inversely proportional
Stratosphere Directly proportional
Mesosphere Inversely proportional
Thermosphere Directly proportional
Exosphere Directly proportional

51. Atmosphere helps us in many ways:
Breathing comes naturally.
We need oxygen to keep our bodies working. A
radiation shield.
Security Blanket.
The atmosphere also keeps us warm.
Weathering the storm.
Closely related to temperature regulation, the
atmosphere also gives us weather.

52. Atmosphere helps us in many ways:
Look out below!
Another really important thing that the atmosphere
does is to protect us from objects coming toward the
earth from outer space.
Plant life.
The atmosphere is also very important for plants
because it contains a small amount of carbon
dioxide. Plants use the carbon dioxide (CO2) along
with sunshine to carry out a process called
photosynthesis.

53. Atmosphere helps us in many ways:
Let’s Talk.
One more thing the atmosphere does
is it allows us to talk to each other. If
you were talking to your friend and
there were no air between the two of
you, your friend would not be able to
hear a thing you said.

54. It is cooler in Baguio that in
Manila. Baguio is at a higher
altitude than Manila. Shouldn’t
it be warmer in Baguio since it
is a lot closer to the sun?

55. LAYERS OF THE ATMOSPHERE
Objective:
• to determine how the atmosphere
divided into different layers

56. Procedure:
1. Plot the average temp readings at various
altitudes in Earth’s atmosphere.
2. Label the different layers and the
separating boundaries between each
layers and locate the ozone layer
(troposphere, tropopause, stratosphere,
stratopause, mesosphere, mesopause,
thermosphere)
