Earth's Systems
The Earth is made up of four main
interacting systems, which are sometimes
called spheres
Atmosphere
Hydrosphere
Geosphere
Biosphere
The systems interact with one
another by exchanging energy
and matter.
These interactions have resulted in
the Earth changing. These changes
usually take a very long time to
progress.
The Atmosphere
The Atmosphere
The atmosphere is just a... thin layer of different
gases that surrounds Earth
Mostly made up of
Nitrogen (78%)
21% Oxygen
1% Other gases (Argon,
CO2, Water vapor, etc.)
The Biosphere
The Biosphere
The biosphere includes any part of the Earth
where there are living things.
This is where all the bugs,
animals, plants, fungi, etc. live.
It extends from the crust of the
Earth to the atmosphere,
including deep into the oceans.
The Geosphere
The Geosphere
The geosphere includes the Earth's interior, rocks and minerals,
landforms and the processes that shape the Earth's surface.
The lithosphere is
the outermost
layer of the
geosphere
Processes include
continental drift,
volcanoes, and
earthquakes
The Hydrosphere
The Hydrosphere
The hydrosphere includes all of the water on or near the
surface of Earth.
Clouds, ice, oceans, water
vapor, etc.
Cryosphere is the frozen part
of the hydrosphere
What exactly is an interaction?
The processes that move matter and energy
from one sphere to another
