Plate Tectonics Lab (2020 revision)

Maps to use:

This Dynamic Planet (USGS publications) - http://pubs.usgs.gov/imap/2800/

A Global Map/Atlas – The National Geographic Map below can be used or an

equivalent one that includes geographic and sea floor features.

Directions:

Please identify several examples of each of the following plate tectonic settings using the

maps referenced above. Please read the legend at the bottom of the This Dynamic Planet

Map which explains the symbols used on the map. For each example, provide a geographic

name for the setting (e.g., the Andes Mountains, the Mid-Atlantic Ridge, etc.) and identify the

tectonic plate(s) that are involved. The plate names are identified on the This Dynamic Planet

Map.

The This Dynamic Planet Map does not provide the names of associated geologic features. To

find these you will need to use an atlas. Several geographic atlases can be found online (The

link above is for the global atlas from National Geographic), or you can use one that you may

have access to at your home. Be sure you find an atlas that contains the geographic names of

the ocean floor features in addition to the geographic names of land features. Some features

may have more than one geographic feature associated with them. For instance, an ocean-

continent convergent boundary can be identified by the deep-sea trench or by the continental

volcanic arc. You will only need to identify each setting with one prominent geographic

feature, but listing more than one will be useful for you.

Finally, list the general geologic phenomena or features that are typically associated with each

type of plate tectonic features. These can include the following:

• small shallow earthquakes

• large deep earthquakes

• volcanoes

(volcanic island arcs, continental volcanic arcs, or hot spot volcanic tracks)

• deep sea trenches

• oceanic ridges (spreading centers)

• continental mountain ranges (non-volcanic)

Don’t list specific place names or landscape features (like “Mount St. Helens”) – the goal here

is to see what all the examples of this particular type of boundary have in common (like “deep

earthquakes, volcanic island arcs, and deep sea trenches”)

Divergent Boundaries:

Identify five (5) different divergent plate boundaries (spreading centers) on the earth.

What general geologic features/phenomena (i.e., earthquakes, volcanoes, trenches,

mountains, etc.) are associated with this boundary? Be careful, not all features

labeled “ridge” on the map are tectonic spreading centers.
