Earth’s System
• Everything in Earth's
system can be placed
into one of four major
subsystems: land,
water, living things, or
air.
• These four
subsystems are
called "spheres."
Atmosphere and its sub spheres
What is it? Composition?
Where is Ozone layer? Protect us from what?
Hydrosphere

• What is it?
• Different stages
• Add Evapotranspiration and Aquifer
Hydrosphere Distribution
Lithosphere
• What is it?
Biosphere
• What is it?
• Protists, Animals,
Plants, Fungi, and
Bacteria
Anthrosphere –Sub Sphere
• What is it?
• Technosphere
• Deforestation for housing and land setup

Magnetosphere or geomagnetosphere is in
space, protects us from solar winds and
suns radiation
Asthenosphere is the nonrigid layer below
the lithosphere, convection currents within
move the tectonic plates
Geosphere is the densest parts of Earth,
which consist mostly of rock and a
heterogenous mixture. The dense
geosphere is also subdivided into the crust,
mantle, and core.
Pedosphere is the outermost layer of the
Earth that is composed of soil and subject to
soil formation processes. It exists at the
interface of the lithosphere, atmosphere,
hydrosphere and biosphere.
Ionosphere or plasmasphere is a sub sphere
of the atmosphere, outermost part
Cryosphere is the portions of the Earth’s
surface where water is in solid form;
including sea ice, lake ice, river ice, snow
cover, glaciers, ice caps and ice sheets,
and frozen ground (which includes
permafrost).
