Plate Motions

Plate Puzzle
Develop a better understanding of the Earths
plates and their distribution. Explore plate
motions and the interactions of the plates along
the plate boundaries. Cut map along plate
boundaries.
Each student selects a plate. The students work t
ogether to put the plate puzzle together.
Students discuss relative plate motion for
neighboring plates and agree on type of plate
boundary. Makes a good authentic assessment.

A once in a lifetime opportunity!!!
Join us in a
Take a virtual journey to the Earths center
- Using a classroom-, hallway-
or playground-sized scale model
- View the structure of the interior of the
Earth - Learn about the conditions in the
deep interior, all the way
to the center of the inner core
- Discover surprising facts
about the Earths interior
- Use as a thematic activity
by connecting to Jules
Vernes classic book or
the 1959 movie - Tour guide
brochure and narrative provided
Tour the inside of the planet in under one hour!
Discover the structure of the Earths interior!
Experience the conditions deep below the surface!

Plotting Earthquake Epicenters
Create a plot of worldwide earthquake
epicenters to display the narrow zones
of seismic activity of the Earth and aid
in an understanding of plate tectonics.
Students discover that about 95 of
earthquakes occur along plate bound-
aries where the lithospheric plates
(about 100 km thick shell of relatively
cool, rigid and brittle rock overlying the
softer, hotter asthenosphere zone with-
in the Earths upper mantle) move with
respect to each other in three ways ? diverging
or moving apart (such as at the mid-ocean
ridges), converging or colliding (such as along
the west coast of South America, the Aleutian
Islands, or the western Pacific) and transform or
horizontal slipping (such as along the San
Andreas fault in California).
13
It is useful to initially perform the epicenter
plotting activity "by hand." The experience
allows the student to fully understand the
characteristics of the data, learn how to obtain
real and timely earthquake data from the
Internet, and practice map skills, including long
itude and latitude, directions, two-dimensional
interpolation, and basic world geography. Ext
ensions to this activity are described
that include producing maps with computer
software or from the Internet.

Plotting Epicenters

• Mapping Skills latitude and longitude
• Directions
• Basic Geography
• Patterns looking for boundaries
• Integrating Technology researching daily events

15
Individual Student Maps

• book mapping - tracking India
• Plotting epicenters from current data collected
  from internet source such as IRIS
  
• Predicting hazards
• Flip

16
Classroom mapping

• Involve students in long term data collecting
  project
  
• Use technology to get events periodically - 2-3
  days per week
  
• Cooperative project
• Locate earthquakes that are in the newspaper for
  current events
  
• Stimulate interest as patterns emerge

17
Materials needed

• World wall map you can put stickers on
• Colored dots, 3 sizes multicolor packages
• Current data from internet IRIS web site
• Maps for puzzles, large floor maps or individual
  student maps

Seismic/Eruption
Seismic/Eruption includes up-to-date earthquake
and volcanic eruption catalogs and allows the
user to display earthquake and volcanic eruption
activity in speeded up real time on
global, regional or local maps that also show
the topography of
the area in a shaded
relief
map image.

Seismic/Eruption is an
interactive
program that
includes a number of tools

that allow the user to

analyze earthquake and

volcanic eruption data and

produce effective displays

to illustrate seismicity and

volcano patterns.
