E.Q.
HOW DOES EACH SYSTEM AFFECT HUMAN L IFE?
BIOSPHERE
The biosphere is the sphere that encompasses
all life on Earth, so it's quite clear what impact
it has on human life -- without the biosphere,
we would not be alive.
HYDROSPHERE
• The hydrosphere is the sphere that
encompasses all water on Earth.
• The hydrosphere is where we get the water cycle
(hydrologic cycle) from.
• Water can change states among liquid, vapor, and
ice (cryosphere) at various places in the water
cycle.
• Without the hydrosphere, we would all die from
dehydration.
GEOSPHERE
• The geosphere is the solid portion of the
earth.
• It supplies all of the raw materials that we
need to build up our bodies.
• This sphere also gives us something to walk
on.
• Without the geosphere, there wouldn’t even
be a planet since Earth itself is made up of a
mantle, and inner and outer core.
ATMOSPHERE
• The atmosphere protects us from dangerous radiation
from the sun.
• This sphere also keeps us warm.
• It gives us weather.
• It protects us from objects coming toward the earth
from outer space.
• It gives us air to breathe.
CONCLUSION
Overall, all 4 spheres need each other in
order for the Earth to work the way it
does. Without one sphere working
properly, the Earth suffers. We, as
humans, all need each sphere to be
working!
HOW DOES EARTH’S SYSTEMS AFFECT LIFE ON EARTH?
HOW DOES EARTH’S SYSTEMS AFFECT LIFE ON EARTH?
WHEN ONE OF EARTH’S SYSTEMS UNDERGOES A CHANGE OR EXPERIENCES A
CATASTROPHIC EVENT, IT AFFECTS ALL OTHER SYSTEMS OF THE EARTH.
Ex: When a volcano erupts it is an interaction of all of Earth‘s systems. Magma and ash from the geosphere devastates the wildlife and vegetation which is the biosphere. The volcano also releases large amounts of CO2 and ash into the atmosphere. If the volcano is near water, it affects the hydrosphere too.
EARTH’S SYSTEMS INTERACT WITH EACH OTHER DUE TO
THEIR INTERDEPENDENCE ON ONE ANOTHER.
The biosphere needs water from the hydrosphere, and oxygen from the atmosphere, to survive.
THE ATMOSPHERE RECEIVES
GASSES FROM THE BIOSPHERE
AND WATER FROM THE
HYDROSPHERE.
THE GEOSPHERE
GIVES MINERALS TO THE
BIOSPHERE, ATMOSPHERE,
AND THE HYDROSPHERE
. HUMANS, AS PART OF THE BIOSPHERE,
ALSO HARNESS FORCES OF THE
HYDROSPHERE (LIKE RIVERS) FOR POWER.
THE HYDROSPHERE, AND THE ATMOSPHERE SHAPE
THE GEOSPHERE THROUGH THE
WEATHERING OF ROCKS AND SOIL.
THE ATMOSPHERE IS WHERE WEATHER OCCURS. THE ATMOSPHERE DETERMINES THE CLIMATE FOR A REGION, WHICH AFFECTS THE BIOSPHERE BY DETERMINING WHERE PLANTS AND ANIMALS CAN LIVE, AND THE GEOSPHERE THROUGH WEATHERING.
MY EQ!
How does the Atmosphere
interact with all of the
other spheres?
INTRODUCTION
The subsystems of the Earth interact
with one another in
all things. Every process happens
from the smallest of sizes to the
largest of sizes, and on time scales
that range from milliseconds to
billions of years.
THE LAYERS, (WITH EMPHASIS ON : THE ATMOSPHERE)
Geosphere- consists of the core, mantle and
crust of the Earth.
Atmosphere- contains all of the Earth’s air and
is divided into troposphere, stratosphere,
mesosphere, thermosphere and ionosphere.
Hydrosphere- contains all of the solid, liquid
and gaseous water on Earth,
Biosphere- is the collection of all Earth’s life
forms.
Our atmosphere is a weird place.
LET’S TALK ABOUT IT!
OUR ATMOSPHERE
Obviously, everyone has to breathe. We need oxygen to
keep our bodies working. Just try holding your breath
for a few seconds and see what happens. People are
not the only ones who need oxygen; all kinds of
animals need it too. Without the atmosphere, we would
all quickly die. The atmosphere of Earth also protects
us and all living things on the earth from dangerous
radiation from the sun.
These are the 5 Layers of the Atmosphere! Well, only 4 are shown so far.. But, the Exosphere will be brought up in the last slide!
Here is the Troposphere!
Next, is the Stratosphere!
Here comes the Mesosphere!
Welcome to the Thermosphere!
EXOSPHEREAnd now, lastly is the Exosphere!
HOW DO THE DIFFERENT SYSTEMS OF THE EARTH INTERACT AND AFFECT ONE ANOTHER?
E.Q.
WHAT ARE EARTH SYSTEMS?
• Well, Earth is divided into 5 different systems. Cryosphere, Biosphere, Geosphere, Atmosphere, and Hydrosphere.
• Earth’s systems have a wide range of different climates and conditions!
• For example, the Cryosphere is very cold, and the Geosphere is quite rocky.
• All of these systems interact (Interaction) with one another.
• The biggest system is the Geosphere.
CRYOSPHERE
• The term “Cryosphere” comes from the Greek word,
“krios” which means cold.
• People who study the Cryosphere are called Snow
Hydrologists.
• Snow Hydrology is a branch of Hydrology, which
studies the composition, dispersion, and movement
of snow and ice.
HYDROSPHERE
• The hydrosphere includes all of Earth’s water.
• Oceans, seas, lakes, ponds, rivers and streams are all a part of the Hydrosphere.
• The hydrosphere covers about 70% of the surface of the Earth, and is the home for many plants and animals.
GEOSPHERE
• The Geosphere goes through many cycles which makes up our geosphere as we see it today.
• Cycles - a series of events that are regularly repeated in the same order.
• People who study the Geosphere are called Geodesiologists.
BIOSPHERE AND ATMOSPHERE• Both of these go together since the Biosphere
needs the Atmosphere. Not saying they don’t need the others, but without an Atmosphere there would be no ecosystem as we see it today.
• The term “biosphere” was coined by geologist Eduard Suess in 1875,
• People who study the atmosphere are known as Climatologists,
• Climatology - study of climate over long-term trends in global weather
• A Climatologist would most likely be the one studying the Atmosphere.
