Exploring Geology Using Google Earth
1. Visit digital.wwnorton.com/geolabmanual4
2. Go to the Geotours tile to download Google Earth Pro and the accompanying
Geotours exercises file.
Expand the Geotour07 folder in Google
Earth by clicking the triangle to the left of
the folder icon. Check and double-click the
New England Metamorphic Zones overlay
to see a metamorphic grade map draped
over the Appalachian Mountains of New
England (note that you can select the overlay
and use the transparency slider at the bottom
of the Places panel to make the overlay semitransparent).
(a) Check and double-click the Grade
placemark. If you traveled north from the
(a) placemark, would you go into higher
or lower metamorphic grade rocks?
(b) Check and double-click the West & East placemarks. Based on your answer to (a), would the metamorphic core
(the zone of highest metamorphism) of this region be near the West or East placemark?
(c) Check and double-click the Schist placemark. Based on the location of the placemark, what are the red minerals in
the schist pictured in the placemark balloon?
(d) Considering the area covered by the New England Metamorphic Zones overlay, what type of metamorphism likely
produced these metamorphic rocks?
