1. Why are the Appalachian Mountains
generally rounded in appearance?
Answer: The
Appalachians are generally rounded because of the effects of erosion,
particularly by ice sheets. Below, we have a present day example of this
happening in the New Zealand Southern Alps.
Theme Study (A):
Vertical metamorphic sequence
(SITE: 2)
Rock type:
Mainly greywacke and schist
Location: Franz Josef Glacier, Southern Alps, New Zealand
Feature: Cliffs of highly metamorphosed rock,
ice-carved glacial valley, active glacier, |
KEY POINTS: Glacier travels downwards
into zone of higher grade metamorphism (schists). It collects and deposits
rocks of different layers. Glacier has carved steep-walled valley typical of
this form of erosion. Glacier periodically advances and retreats. |

Labrador, close to the Quebec border.

3. b) Prince
Edward Island has the largest share of lowlands.
Prince Edward Island National Park of Canada
Prince Edward Island National Park of Canada is home to sand dunes, barrier
islands and sand pits, beaches, sandstone cliffs, wetlands and forests. These
diverse habitats provide a home for a variety of plants and animals, including
the endangered Piping Plover. The National Park also features unique cultural
resources, notably Green Gables and Dalvay-by-the-Sea National Historic Site.
In 1998, six kilometres of the Greenwich Peninsula were added to the Park to
protect unique dune formations, rare plants and animals, as well as
archaeological findings dating back 10,000 years.
3. c) The
highest point of land in Prince Edward Island is 142 m. in Queen's County.

5. Fiords
are found in coastal regions around the globe, in the higher latitudes of the
Northern and Southern hemispheres. They developed along mountainous western
coasts where glaciers carved deep chasms through ancient river valleys or along
lines of structural weakness (geological).
