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.

2. a) Newfoundland and Labrador have the highest point of land in the Atlantic Region.

2. b) Mount Caubvick 1652 metres (part of the Torngut mountain range) is about 200 km from the northern tip of Labrador, close to the Quebec border.

Prince Edward Island National Park of Canada


Prince Edward Island Greenwich, 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).
