- A college professor of history has become
fascinated that ancient geologic events created our landscape
and that landscapes have influenced human history, linking
in interesting ways the history of our planet with the history
of people. You are hired part-time by to create for him a
map of the Northeast, with topographic features colored according
to the geologic event(s) that had the most influence on the
topography. In many cases two events were influential, since
the type of rock and structure in the rock combine (after
erosion) to create landforms. Use the following events to
create your map: (1) the Grenville passive margin (2) the
Taconic converge, (2a) interval (Silurian-Early Devonian)
between Taconic and Acadian (3) the Acadian convergence, (3a)
interval (Mississippian-Early Permian) between Acadian and
Alleghenian (4) the Alleghenian convergence, (4a) interval
(Early-mid Triassic) between Alleghanian and rifting (5) the
rifting apart of Pangea, and (5a) interval (mid-Jurassic-late
Jurassic) between rifting and creation of Coastal Plain (6)
the Coastal Plain passive margin and shaping by erosion of
many of current land-forms (7) Pleistocene glaciation and
Holocene post-glacial. Create a map for the professor,
using your creativity and judgment to make the map easy to
read; you will have to generalize some detail.
- Your local Visitors Association hears about
your project and recognizes that it may be interesting for
them to describe the history of the your area in terms of
landforms and geologic events, in their dealings with tourists
to your community. You suggest that you may not be able to
interpret every landform, but the Visitors Association representatives
say that having a few interesting examples is more important
than completeness Describe your local topography in terms
of geologic history, underlying rock type, and erosion.
- Seeing that the Visitors Association is creating
business from your knowledge, you sense an entrepreneurial
opportunity: you could sell, to communities throughout the
Northeast, interesting geological information about landforms
to businesses advertising about their geographic areas and
tour guides wanting information about the local scenery. To
take a stab at starting your own business, you choose several
widely separated locations to link topography to geological
history. Create a description like (2) for several locations.
Create also a pricing sheet that indicates cost for your work.
