Welcome to Earth
Science!
Chapter 1: The Nature of
Science
BIG Idea:
Earth Scientists
use specific methods to
investigate Earth and beyond.
I.
What is Earth Science?

the study of the Earth and the
universe around it…

the study of Earth systems and
systems in space; including weather
and climate systems, and the study
of nonliving things such as rocks,
oceans, and planets.
A. The Scope of Earth Science:
1. Astronomy: the study of
objects beyond Earth’s
atmosphere.

The oldest branch of
Earth Science.
2. Meteorology: the study of
Earth’s atmosphere.

Weather
Forecasters

Tornado Chasers
3. Geology: the study of the
origin, history, and structure of
Earth.
4. Oceanography: the study of
the life and properties of Earth’s
oceans.

JACQUES COUSTEAU
How
much
of our Earth
is covered
by OCEAN
water?
almost
three-fourths!
5. Environmental Science: the
study of the interactions of
organisms and their
surroundings.
B. Earth’s Systems
1.
Geosphere: the area from the
surface of Earth down to its
center.
 Three main parts:
a) Crust
b) Mantle
c) Core
 Inner core
 Outer core
2.
Atmosphere: the blanket of gases
that surrounds our planet.
3.
Hydrosphere: all the water on
Earth.
4.
Biosphere: all organisms on
Earth and the environments in
which they live.
