Volcanoes and Earthquakes

I have approached this event by teaching a-q as individual sessions. Using the computer allows the team

members to teach themselves.

Shield Volcano

A shield volcano  is is typically built by eruptions of fluid, basaltic lava. The take on the appearance of shield with the convex side facing upward. The Hawaiian Islands are an example of shield volcanoes.

Shield Volcano

Composite Volcano

A composite volcano is built by alternating eruptions of lava and pyroclastic material. Composite volcanoes, also called stratovolcanoes, form tall conical mountains.

Cinder Cone

Cinder cones  are constructed from the deposition of cinders and other pyroclastic material. Tend to be smaller in height than stratovolcanoes and have an asymetric cone.

Volcanic Hazards - Lahar

Lahar mudflow of volcanic ash and dust created when pyroclastic material is mobilized by melting snow or rain. An extremely dangerous environmental hazard.

Volcanic Features

Using Google video, research “crater lake”. A nice 1:04 video by Britannica.org is available from youtube.com.

Volcanic Features

Should be able to identify and explain how this feature became to be.

Seismograms and Characteristics of P, S,

and Love Waves

You should know which of the waves is the fastest, how the waves travels, which is considered body vs. surface waves,

and HOW to determine the epicenter!http://www.seismo.unr.edu/ftp/pub/louie/class/100/seismic-waves.html

http://nemo.sciencecourseware.org/VirtualEarthquake/ - MUST DO!

Earth’s Interior

Be able to name the various layers

Why the layers are important?

Where are the layers found?

Moho Layer(Where and) Why is this layer important?

The boundary where Earth's crust meets Earth's upper mantle (approximately 31 mi/50 km below the surface), and where seismic waves travel at a different and more rapid rate than the crust or mantle.

Measuring Ground Movement

Mercalli Scale vs. Richter Scale

Intensity should not be confused with magnitude

Emergency Preparedness

Climate Change as related to volcanic activity

http://www.cotf.edu/ete/modules/volcanoes/vclimate.html

You should be able to understand the short term and long term effects. What gases are released and why are these gases important to the weather/climate? What level of the atmosphere does gases affected the climate? What is the “Year without a Summer”?

For help, you should be able to ask last year’s Meteorology team members.

Topographic Map

Plate Tectonics

Plate tectonics is the geophysical theory in which the earth's crust is broken into huge plates that move about laterally and vertically. The interaction of lithospheric plates creates second order relief features of the earth, e.g. mountain chains, deep valleys.

Plate Boundaries(1) Convergent, (2) Divergent and (3) Transform

Evidence of Sea Floor Spreading http://www.sci.csuhayward.edu/~lstrayer/geol2101/2101_Ch19_03.pdf

Nice Videos (Sea Floor Spreading 1:11, Mid Atlantic Ridge :57) http://videos.howstuffworks.com/science-channel/29268-100-greatest-discoveries-sea-floor-spreading-video.htmA lot of videos other good stuff…just need to look around

http://video.yahoo.com/watch/1595570/5390151Bill Nye’s Sea Floor Spreading for the Discovery Channel

Sea-floor spreading occurs where oceanic plates are diverging from one another. Magma rises along a rift zone and spreads out at the surface building new sea floor. As a result, the age of the rocks increases as one moves away from the rift zone. The mid-oceanic ridge is the primary site for sea-floor spreading. Earthquakes and volcanoes are where sea floor spreading is occurring.

Magnetic stripes record the magnetic polarization of iron-bearing rocks from a magnetometer. Deciphering magnetic stripes was one of the pieces of evidence to support the theory of sea floor spreading and plate tectonics.
