ENVIRONMENTAL SCIENCE:
The scientific study of our environment as well as our role
in it.
WELCOME TO
ENVIRONMENTAL SCIENCE 10
(ES 10)
An interdisciplinary study that examines the role of
humans on the earth. It is a physical, biological and social
science.
Spring 2017
We will focus on information from a variety of disciplines.
Christa Fink, David Schwartz &
Lauren Hanneman
Topics include: geological processes, hydrology,
oceanography, natural resources, climatology, population
biology, ecosystems, biodiversity, biochemistry and the
chemistry of pollution. ES 10 will also how human
behavior and institutions affect the environment.

Caution: This project is for extremely reliable, mature and responsible students
only!!! We are looking for students who will enjoy the course and students who
like to work in groups. Points will be lost for tardiness or absences. All 6 meetings
are required.

Today: Intro to Plate Tectonics:
What is it? The myths?
Definition, what the plates are made up of
“Boundaries = Geologic Activity”
Hazards and Resources: Associations
Study Guide / Key Concepts
Define Plate Tectonics
What is the lithosphere? What is the Asthenosphere? What are they each
composed of?
Name the 3 types of plate boundaries and describe the motion associated with
each. Define the process of Sea Floor Spreading? How do scientists know SFS
is occurring.
A brief
overview of
Plate Tectonics
What is subduction? Where does it occur?
List a few examples of where each types of boundary is located. Plate Tectonic
geography is important.
List a few examples of continental margins that are 1,000’s of miles away from
the nearest plate boundary. These are called “Passive”.
What types of geologic activity are associated with lithospheric plate
boundaries? This is important, list as many as you can.

Plate Tectonics
Plate Tectonics
• Outer layers of Earth made up of ~ 12 major
individual rigid plates (“Lithospheric/Tectonic
Plates”)
• Plates move in response to convection in the
mantle
• Most geologic activity occurs near plate
boundaries (3 types of boundaries)

Plate Tectonics; The Boundaries
Divergent Boundaries
Sea Floor Spreading on Oceanic Ridges
Typically shallow focus and small earthquakes

Convergent Boundaries
Subduction @ deep sea trenches,
shallow to deep focus earthquakes

In ES 10, we will think about things
humans do to the environment AND things
the environment does to humans.
“You can’t just do one thing; there will
most likely be unintentional consequences.”
