Geological dating of mountains
It applied massive stress on what is today the Eastern Seaboard of North America, forming a wide and high mountain chain.
The Appalachians likely once reached elevations similar to those of the Alps, Andes, and the Rocky Mountains before they were eroded down to what they are today.
Quebec is also a peninsula, surrounded on 3 sides by salt water (Atlantic Ocean, Labrador Sea and Hudson Bay) and divided by the St.
Lawrence river one of the world's largest freshwater river systems.
Quebec's geology has been influenced by early geological events and, most recently, by the last glaciation that ended over 10 000 years ago and covered most of Quebec in giant sheets of ice.
In the last 3000 years, Quebec's main vegetation zones were established.
Take the ferry to Bell Island and descend into an iron ore mine that operated from 1896 to 1966.
Some streams flowed along weak layers that define the folds and faults created many millions of years earlier.This part of Alabama formed in the shallow waters that have covered most of the central continent throughout geologic history.The Tuscaloosa Group gives way to the compressed, folded rocks of the southernmost Appalachian Mountains to the northeast and the flat-lying limestones of the interior basins to the north.First, let's look at Quebec as a whole: it is a land mass covering 1.67 million square kilometres.Understandably, such a huge area of land will be diverse in both climate and geology, factors which influence how much diversity exists in a given place.
