P2.1 Branches of Earth Science
1. Branches of Earth Science
Imagine that you are an earth scientist and can travel wherever
you want to on earth.
• Name and describe the aspects or features of earth you
would like to study.
• Where you would go and what you would do?
2. Objectives
Describe the four major branches of Earth science.
Identify four examples of Earth science that are
linked to other areas of science.
3. Four Major Branches of Earth Science
Geology
Oceanography
Meteorology
Astronomy
4. Geology
The study of the origin, history, and structure of the
Earth and the processes that shape the Earth.
Most geologists specialize in a particular aspect of
the Earth.
Volcanologist
Seismologist
Paleontologist
5. Oceanography
Scientific study of the sea
Physical oceanographers
Biological oceanographers
Geological oceanographers
Chemical oceanographers
Oceanographers use miniature research submarines
to travel far below the surface of the oceans
6. Meteorology
Scientific study of the Earth’s atmosphere, especially
in relation to weather and climate.
Meteorologists warn people about severe weather
such as hurricanes and tornadoes
Some meteorologists chase tornadoes and fly
through hurricanes to study how they behave
7. Warmup
Without looking back try to name the 3 branches of
Earth Science we talked about yesterday and list
something specific that they study.
For example…
Biology: frogs
Chemistry: hydrogen atoms
8. Astronomy
Study of the universe
Astronomers use optical telescopes to see distant
objects
Radio telescopes use radio waves to study objects
that are too far away to be seen or that do not give off
light
9. Astronomy
Astronomers spend much of their time studying
stars.
Astronomers estimate that there are over 100 billion
stars in the universe.
The star that has been studied the most is the one
that is closest to Earth––the sun!
10. Special Branches of Earth Science
Other branches of Earth Science rely heavily on other
areas of science
Environmental Science - Study of how humans
interact with the environment
These scientists use geology, life science, chemistry, and
physics.
11. Ecology
Study of communities of organisms and their
nonliving environment
Ecologists work in fields such as wildlife
management, agriculture, forestry, and conservation.
12. Geochemistry
Study of the chemistry of rocks, minerals, and soil
Geochemists judge the economic value of materials
from the earth, determine what the environment was
like when rocks formed, and study the distribution of
chemicals.
13. Cartography
People who make maps of the surface features of the
Earth
Cities are often located by geographic features, such
as rivers, that are used for transportation.
