Question

the great lakes - name the 5 great lakes, explain how they form and provide evidence. examples of freshwater and salt (marine) water. what is an estuary? locations? importance?

Explanation:

An estuary is a partially enclosed coastal body of water where freshwater from rivers and streams mixes with saltwater from the ocean. Freshwater examples include the Amazon River estuary, and salt - water (marine) examples are the Chesapeake Bay. The five Great Lakes are Lake Superior, Lake Michigan, Lake Huron, Lake Erie, and Lake Ontario. They formed from glacial activity during the last ice age. Glacial erosion created large basins which filled with meltwater as the glaciers retreated. Evidence includes the U - shaped valleys and moraines in the region. Estuaries are important as they serve as nurseries for many fish and shellfish species, help in filtering pollutants, and are important for recreational activities.

An estuary is a partially - enclosed coastal body of water where freshwater and saltwater mix. Freshwater and salt - water estuary examples can be the Amazon River estuary and Chesapeake Bay respectively. The five Great Lakes are Lake Superior, Lake Michigan, Lake Huron, Lake Erie, and Lake Ontario. They formed from glacial activity during the last ice age with evidence like U - shaped valleys and moraines. Estuaries are important for aquatic life, pollution filtering, and recreation.
