The Earth’s Physical Systems
Atmosphere, Hydrosphere,
Lithosphere, and Biosphere
Earth System (4 physical systems)
Atmosphere
Layer of gases that surround Earth. Allows
you to breathe and protects earth.
Lithosphere (crust and MOHO)
Surface of the planet that forms the continents
and the ocean floor.
Earth System (4 physical systems)
Hydrosphere
All the water on Earth (ocean, ice, and water
vapor in the atmosphere)
Biosphere
Part of Earth where life exists.

Human Actions Affecting the Atmosphere
NEGATIVE
Ozone Depletion
UV rays can destroy a type of
bacteria known as
Cyanobacteria which produces
much of Earth's oxygen.
Exposure to harmful UV rays
can cause skin cancer and
cataracts.
An excess level of UV rays
could lead to the death of the
phytoplanktons, that are an
important component of the
food web of the oceans.
Global warming
Glacier melting which leads to
flooding
Changing weather
POSITIVE
Clean Air Act
Human Actions Affecting the Lithosphere
NEGATIVE
Over Harvesting
•imbalance in the food chain
the death of a species
Air and Water Pollution
• Weathering
• Loss of useful water
POSITIVE
Reforestation
Restocking of fish
Water purification
Human Actions Affecting the Hydrosphere
NEGATIVE
Pesticides
washing into river
systems
Decline of quality
groundwater
Acid Rain
Damages trees at high
elevations
decay of building
materials and paints,
including irreplaceable
buildings, statues, and
sculptures
harmful to public health
POSITIVE
Release of oceanic
carbon dioxide
Human Actions Affecting the Biosphere
NEGATIVE
Deforestation
flooding
landslides and mudslides
trees are an important part of
the water cycle
forests home to a large
number of animals
Strip Mining
water pollution
landslides
fires
hazards to public health &
safety
POSITIVE
Prevention of forest fires
by proper forest
management
