1. EARTH SCIENCE
EARTH - IS THE ONLY PLANET IN THE UNIVERSE
KNOWN TO PROSSESS LIFE.IT HAS AIR THAT WE CAN
SAFELY BREATH IN, LAND WE GROW OUR CROPS AND
WHERE MANY PLANT AND ANIMAL,SPECIES, INHABIT
AND MOST IMPORTANTLY, WATER WHICH PROVIDES
WIDE ARRAY OF ESSENTIAL USES AND WHICH SERVES
AS HOME FOR AQUATIC LIFE

2. THE EARTH FOUR SUBSYSTEMS ➡

3. GEOSPHERE
The geosphere is the earth itself: the rocks, minerals, and
landforms of the surface and interior. Below the crust –
which varies in depth from about 5 km beneath the ocean
floor to up to 70 km below the land surface, temperatures
are high enough for deformation and a paste-like flow of
elements.

4. HYDROSPHEERE
The hydrosphere includes water that is on the surface
of the planet, underground, and in the air. A planet's
hydrosphere can be liquid, vapor, or ice.
On Earth, liquid water exists on the surface in the form
of oceans, lakes, and rivers. It also exists below ground
—as groundwater, in wells and aquifers.

5. ATMOSPHERE
atmosphere is a layer of gas or layers of gases that envelop
a planet, and is held in place by the gravity of the planetary
body. A planet retains an atmosphere when the gravity is
great and the temperature of the atmosphere is low.

6. THE FOUR LAYERS OF THE ATMOSPHERE

7. TROPOSPHERE
THE LOWEST LAYER OF THE ATMOSPHERE WHERE
WE LIVE AND WHERE WEATHER HAPPENS. IT IS
WHERE MOST OF THE WATER VAPOR PRESENT IN
THE ATMOSPHERE IS FOUND TEMPERATURE IN
THIS LAYER DECREASES AS THE ALTITUDE
INCREASES HOWEVER, TEMPERATURE STOP
DECREASING AT THE TROPOPAUSE.

8. STRATOSPHERE
WHERE TEMPERATURE INCREASES DUE TO THE
PRESENCE OF OZONE LAYER IS WARM BECAUSE IT
ABSORBS ULTRAVIOLET RAYS FROM THE SUN
WHICH PRODUCTS LIFE ON EARTH.

9. MESOSPHERE
THE LAYER ABOVE THE STRATOSPHERE WHERE
TEMPERATURE DECREASES WITH HEIGHT. IT
CONTAINS RATIOS OF NITROGEN AND OXYGEN
SIMILAR TO TROPOSPHERE, EXCEPT THE
CONCENTRATIONS IS 1000 TIMES LESS AND
THERE'S LITTLE WATER VAPOR, SO THE AIR IS
TOO THIN FOR WEATHER TO OCCUR.

10. THERMOSPHERE
THE UPPERMOST LAYER OF THE ATMOSPHERE
WHERE TEMPERATURE INCREASES WITH HEIGHT
BECAUSE IT IS BEING DIRECTLY HEATED BY THE
SUN.

11. BIOSPHERE
Biosphere is a global ecosystem made up of living
organisms (biota) and the nonliving (abiotic) factors
that provide them with energy and nutrients. The
biosphere is a narrow zone on the surface of the earth
where soil, water, and air combine to sustain life. Life
can only occur in this zone.
