Earth’s Spheres
And how they affect each other
Earth is divided into 4 main SPHERES
Biosphere -Thin layer of air, land,
and water where living things exist.
Includes all living things and their
relationships
Ranges from 10km above sea level
(used by birds in flight) to depths
of the ocean such as the Puerto
Rico trench, at more than 8
kilometres deep.
Geosphere
• All of the rocks, minerals
and ground found on
and in Earth
• Includes all mountains
on the surface, as well as
liquid rock in the mantle
below the surface as well
as minerals and metals
of the outer and inner
cores.
Hydrosphere
• Includes all of the rivers, lakes,
streams, oceans, groundwater,
polar ice caps, glaciers and
moisture in the air (like rain and
snow).
• The hydrosphere is found on the
surface of Earth , but also
extends down several miles
below, as well as several miles
up into the atmosphere.
Atmosphere
• Includes all the air
above the surface of
the Earth all the way
to space.
• The air contains 79%
nitrogen, less than 21%
oxygen, and a small
amount of carbon
dioxide and other
gases.
