Chapter One: Introduction
to Earth Science
1.1 What is earth science?
Text pp 2-5
• The group of sciences which deals with Earth and its neighbors in space.
Geology is the study of all the material
that makes up Earth and the processes
that shape the planet.
Geologists study
the way that these
objects formed,
their composition,
how they interact
with one another,
how they erode,
and how humans
can use them.
• An example of
a geologic
event on earth
would be a
volcanic
eruption.
Other geologic events could be mountain
formation, earthquakes or the movement of
tectonic plates.
Oceanographyintegrates
chemistry,
physics, geology
and biology.
Oceanographersstudy seawater
composition and
movements, coastal
processes, seafloor
topography and
marine life.
• An example of an oceanic event would be an ocean wave.
• Meteorology IS
NOT the study of
meteors!
• Meteorology is
the study of the
atmosphere,
including
weather and
climate.
• Meteorologists can also be called
Climatologists. One of the most
important events that meteorologists
study today is “Global Warming.”
Other
meteorological
events include
hurricanes,
tornadoes, and
rainstorms.
Astronomy represents science
beyond earth. It is the oldest known
science.
Astronomy is the study of the
universe, its formation and all the
objects within it.
An example of
an astronomical
event could be a
solar flare
coming off the
surface of the
sun.
Other astronomical events include a
comet’s orbit, a solar eclipse or the
explosion of a star, also called a nova.
The first topic of earth science we
will discuss is the solar nebula
hypothesis.
First, though….
how do you think the solar
system was formed?
