Transcript of Great Lakes - St. Lawrence Lowlands

Great Lakes - St. Lawrence Lowlands
What era was the Great Lakes Lowland created in?
Created in Paleozoic Era
Topography

The Great Lakes-St. Lawrence Lowlands is located at the southern regions of Ontario and Quebec.
It consists of the Great Lakes lowlands to the west and the St. Lawrence Lowlands to the east
Small yet highly populated area
This region is the most southerly region in Canada
Landscape is made up of plains with glacial hills and deep river valleys
Well suited to agriculture because of its amazing soils and warm climate
Deep, arable soils deposited during the last glaciations

What are the main type(s) of rocks?
The main type of rock in the Great Lakes Lowlands is the sedimentary rocks
All lowlands have bedrock formed from sedimentary rocks
The bedrock is known as Paleozoic bedrock
Paleozoic bedrock can be seen in different parts of the Great Lakes
How was it formed?
Was formed by glaciation and faulting
This occurred because the flat plains were disrupted with glacial hills and deep river valleys
Faulting took place which means that a rift valley was formed
Best known escarpment
The best known escarpment is the Niagara Escarpment. It extends from Niagara Falls to Manitoulin Island. The most famous part of the escarpment would obviously be the Niagara Falls. It was formed by differential erosion. Differential erosion is when softer and weaker rocks are worn away while harder and stronger rocks are there to create different types of platforms.
Human and Economic Activities
Resources in these lowlands:
Farmland
Minerals
Forests
Water

Economic Activities:
The Great Lakes are used for their fresh water and as a waterway for transportation of goods
The region has prime agricultural land on the Niagara Peninsula, where grapes, peaches, pears, plums, and other fruit are grown.
Dairy farming
Iron, zinc, silver, coal copper, and lead
Service Industries
Forestry in the 1900's
Facts and Statistics about the Great Lakes - St. Lawrence Lowlands
Makes up only 1.4% of Canada's total area
Is the most densely populated area in Canada
Has approximately 50% of Canada's total population.
70% of Canada's manufacturing industries are located in this area.
Toronto and the surrounding areas are comprised or more than 100 ethnic groups
50% of the jobs here are related to manufacturing.
More Human and Economic Activities
Economical Activities:

The area around Montreal is a financial, service, and industrial center
It produces fabric, clothes, food, paper, metal, chemical, and wood
Montreal is the center of a major Atlantic transportation network including Canada 's Aeronautics and space industry
Most of these are built on the water for 2 purposes: Hydro - electricity and hard rock platforms.

The St.Lawrence-Great Lakes Lowlands region is one of the smallest regions yet has the most alluring and resourceful landscapes. Not only are the lowlands filled with the amazing views of natural beauty, they're full of perfect agriculture land and minerals.
The Great Lakes
In the Great Lakes part of the lowlands, glaciations created a rolling landscape
Glaciers carried huge amounts of material (soil, sand and gravel) from Canadian Shield and dumped them throughout the region
Great Lakes and St.Lawrence river were even larger than they are now
This is because of enormous capacity of water from melting glaciers
They eventually shrank to the size they are now as glaciers melted & water drained into the ocean.
Topography: Glaciers
Paleozoic Bedrock
It was formed because of double faulting.
Topography: Climate
St. Lawrence Lowlands is closest region in Canada to the equator, so the weather is mild.
Hot humid weather in the summer because of the moisture in the air from precipitation
Winter is unpredictable and can turn sometimes turn out as cold, sometimes not as cold with sticky snow because of the humidity from the Great Lakes
when warm air interacts with cold arctic air, the weather turns out very unstable
up to 80 cm of snow every winter
temperatures go as low as minus 30 degrees Celsius
cause of unpredictability is because of landforms and ocean
In conclusion, the Great Lakes and St. Lawrence Lowlands is a result of faulting. This majestic region is full of nature's beauty and is located in Ontario and Quebec.
