Geological History
In Paleozoic, 300–400 million years ago, the entire territory of the modern Gulf of Finland was covered by a sea. Modern relief was formed as a result of the glacier activities. Its retreat formed Littorina Sea, which water level was some 7–9 meters higher than the present level of the Baltic Sea. Some 4,000 years ago the sea receded and shoals in the gulf have become its islands. Later uplifting of the Baltic Shield skewed the surface of the gulf; for this reason, its northern shores are significantly higher than the southern ones.

Famous quotes containing the words geological and/or history:
“The crystal sphere of thought is as concentrical as the geological structure of the globe. As our soils and rocks lie in strata, concentric strata, so do all men’s thinkings run laterally, never vertically.”
—Ralph Waldo Emerson (1803–1882)
“There is a history in all men’s lives,
Figuring the natures of the times deceased,
The which observed, a man may prophesy,
With a near aim, of the main chance of things
As yet not come to life.”
—William Shakespeare (1564–1616)
