of study:
– Astronomy
– Geology
– Oceanography
– Meteorology
– Environmental Science
Astronomy
Earth
Science
Astronomy
• The study of objects beyond Earth’s
atmosphere
 Astronomers
study the
universe, which
includes
galaxies, stars,
planets, and
other bodies
they have
identified.
Astronomy
Geology
Earth
Science
Geology
• The study of the
materials that
make up Earth
• The processes
that form and
change these
materials
• The history of the
planet & its lifeforms since its
origin
Geologists
• Identify rocks
• Study glacial movements
• Interpret clues to Earth’s
4.6-billion-year history
• Determine how
forces change our
planet

Geology
Oceanography
Oceanography
• The study of Earth’s
oceans
• Oceanographers
study the creatures
that inhabit saltwater,
measure different
physical & chemical
properties of the
oceans, & observe
various processes in
ocean water.

Meteorology
Geology
Oceanography
Meteorology
• The study of weather-producing forces
in the atmosphere
• Meteorologists also try to forecast the
weather & learn how changes in weather
over time might affect the Earth’s climate.

Environmental Science
• The study of the interactions of humans and
their environment
• Environmental scientists study how organisms
impact the environment positively & negatively.
• Topics of study include: natural resources,
pollution, alternative energy sources, & impact of
humans on atmosphere.
Earth’s Systems
• Scientists have identified 4 main Earth
systems that are unique yet interact with
each other in important ways.
– Biosphere
– Geosphere
– Hydrosphere
– Atmosphere
