1.
The Appalachian Mtn. range extends from ______________________ to ____________________.
2.
At one time, we were joined to __________________________________________.
3.
Hank Williams works at __________________________________________, and plays a
_________________. His favourite kind of music: (go figure…) ____________________________.
4.
The overall length of the range is __________________________ km.
5.
The Appalachians were formed approximately ________ to _________ million years ago.
6.
Geologists search for _______________ on the surface of outcrops, as clues of magma activity.
7.
A large area of Newfoundland could best be described as _________________________________,
as a type of landform or region.
8.
NFLD is one of the world's best sites for observing ____________________________, which are
large sections of the oceanic crust pushed on top of continental crust. This is not common…
9.
Two key indicators of oceanic crustal formation are the presence of _________________________
and __________________________________, observed in/on the rocks.
10. High concentrations of the mineral _______________________ prevent most vegetation from
growing in this area.
11. Glaciers carved out the fiord called ____________________________________________________.
12. The ancient seabed contains other clues within the sands and the clays: _____________________.
13. Generally the sediments are approximately _________ million years old in this region, formed in
the ancient ocean called "__________________________".
14. The breccia was originally formed by underwater _________________________, and contains
critical information.
15. At Greenpoint, a dozen of fossil zones are documented, and well indicated by key fossil types,
such as the example of __________________________________.
16. The layers of mud are now tilted almost ______________________ to their original position.
17. Evidence for the over-riding thrust fault still visible is shown by the presence of crushed rocks,
which is referred to by a French name for mixture: "____________________________".
18. The original spreading apart of the continental plates _________________________, causing the
former ocean to gradually diminish, even being forced up onto the continental plates through the
mountain building process.
19. As the Appalachian Mountain Range has eroded away over time, the sediments have become
part of the _______________________________________, a very significant marine structure.

The Appalachian Mountains - Part 2
Name: _____________________________
1. The province of Newfoundland can be separated into ________ distinct geological zones.
2. Rocks on the western side of NFLD near Dover are ____________ million years old.
These rocks are predominantly _____________________ (type of rock).
3. In the fault zone, rocks are sheared and deformed by intense pressures. These altered
granites are called __________________________.
4. The region around the Avalon zone is relatively ____________, compared to the rest of
NFLD - ideal for herds of _______________________.
5. Rocks of this area are similar to specific groups found in ______________________ and
_______________________.
6. There are rocks called ______________________________ that are unique to the region
of northwest ______________________.
7. Nova Scotia has two very distinct geological areas as a result of plate tectonics. The
boundary is along the ______________________ Group, and illustrates the relationship
to the country of ________________________. This country drifted into N.S.
approximately ______________ million years ago, eventually moving away again
_________________ million years ago. The effect of this continental tango dance is that
100's of km of ____________________ sediments were pushed up, becoming part of the
______________________________.
8. The ___________________________________ is unique to all areas of the Appalachians.
9. The Meguma sediments over time became affected by intrusions of _________________,
which caused contact and regional metamorphism, allowing some granites to
recrystallize __________________.
10. Areas of Nova Scotia where you can see great examples of contact zones are
__________________________________________________________________________.
