Question: 1a after tracing the earthquake trends of epicenters using colored...
Question details
1A.
After tracing the earthquake trends of epicenters using colored
pencil, why do you think that there are small concentrated areas
where there are high numbers of earthquakes?
1B. Why do you think that there are large areas where there
either is no activity or low numbers of earthquakes?
1C. Why might some areas along the trends have no earthquake
activity recorded in the 25 year old record?
1D. Geophysicists have identified seven major tectonic plates.
The major ones on which there are continents are the North American
plate, Eurasian plate, South American plate, African plate,
Australian-Indian plate, and Antarctic plate. There is one plate
that is located mostly in the ocean, the Pacific plate. Where are
these crustal plates located on the map?
1E. In addition, several intermediate-sized and more than a
dozen smaller tectonic plates have been found. The
intermediate-sized plates include : the (1-Car) Carribean,
(2-Cocos) Cocos, and (3-Naz.) Nazca plates in the Americas; the
(4-Phil.) Philippine plate in Asia; and the (5-Arb.) Arabian plate
in the Middle East. Where are these plates on the map?
