Transcript of The Great Lakes

THE GREAT LAKES By: Ingrid Ruiz WHAT ARE THE
GREAT LAKES? These lakes are: Lake Superior
Lake Michigan
Lake Huron
Lake Erie
Lake Ontario WHERE ARE THEY LOCATED? They are all located in North America and encompass the Canadian and United States border. Four out of the five lakes actually make up part of Canada-U.S. border. The fifth lake (Lake Michigan), lies entirely within the United States. WORLD GEOGRAPHY Landforms/Bodies of Water Project The Great Lakes are made up of 5 freshwater lakes. In terms of size (area/volume) and depth... LARGEST & DEEPEST
Lake Superior

SURFACE AREA
31,820 sq mi (82,400 km2)

VOLUME
2,900 cu mi (12,000 km3)

AVERAGE DEPTH
483 ft (147 m)

MAXIMUM DEPTH
1,332 ft (406 m)

SMALLEST & SHALLOWEST
Lake Erie

SURFACE AREA
9,940 sq mi (25,700 km2)

VOLUME
116 cu mi (480 km3)

AVERAGE DEPTH
62 ft (19 m)

MAXIMUM DEPTH
210 ft (64 m)
These five bodies of water fall under the classification of freshwater bodies. In comparison to other bodies of water on Earth that fall into the same category, Lakes Michigan, Erie, Superior, Huron and Ontario make up the largest group of freshwater lakes by surface. THE GREAT LAKES
CONSIST OF 20 % OF THE WORLD'S
FRESH WATER. HISTORY
On August 7th, 1679 a sailing ship commissioned by René Robert Cavelier, and Sieur de La Salle named Le Griffon was the first to travel the upper Great Lakes.
TRANSPORTATION Transport was once an extremely common use for the Great Lakes. However, in recent years, cargo traffic has decreased significantly. Each of the lakes is accessible via the Great Lakes Waterway.
The Great Lakes and its rivers played a huge role in moving people as well as freight during settlement.

The majority of passenger lines in the 1800’s transported immigrants. This was the main business at the time. Various large cities would not exist were it not for their position on the lakes as a freight destination. Thus these cities easily attracted immigrants. However after the construction of railroads and surface roads, freight and passenger businesses died down and eventually disappeared. Only ferries and a small number of cruise ships remained. ECONOMY Today, the Great Lakes are used as a major mode of transport, specifically for bulk goods. 162 tons of dry bulk cargo was moved on the lakes in 2002.

In order of volume: iron ore, grain, and potash.

Unfortunately, for several years now, the total amount of shipping that occurs on the lakes has been experiencing a downward trend.
State and provincial governments bordering the lakes administer the distribution of drinking water from the Great Lakes. This valuable resource provides drinking water to tens of millions of people in the surrounding areas. HUMAN IMPACT Major industries: Tourism and Recreational Boating.
These include several cruise ships as well as sailing ships.

Sport and commercial fishing are also popular on the Great Lakes. (With Native American fishing racking up $4 billion US a year with major catches of salmon, whitefish, smelt, trout, and walleye.)

All kinds of water sports are also common on the lakes.
NICKNAMES NORTH COAST THIRD COAST DUE TO THEIR LARGE SIZE AND NUMBER OF BEACHES AND WETLANDS ALONG THEIR COASTS, AS WELL AS ITS VARIOUS TYPES OF ECOSYSTEMS SOME REGARD THEM AS AN INLAND SEA OR ONE SEA ITSELF. FACT! During the winter season, inland waters of the Great Lakes are capable of providing surfing conditions due to the effect of strong storms and waves. REFERENCES:
