Greenland was the birthplace of Finland

The geological history of our planet is etched into the bedrock, preserving memories of the Earth’s young age. Finland holds some of the oldest bedrock in Europe, dating back over 3.5 billion years. This is more than 3,500 million years, making Finland’s bedrock older than the Earth itself by about a billion years. An international team of researchers in the journal Geology has identified the oldest known bedrock in Finland as formed at least 3.75 billion years ago, originating from Greenland’s bedrock at that time.

During this ancient period, the Earth’s underground chambers were barren, and only simple bacteria lived in water. Creatures resembling crustaceans or fish would not develop in the seas until more than 3.2 billion years later. The memories of this ancient time were found in zircon mineral crystals found in rivers like Tornionjoki, Iijoki, and Oulujoki, which had eroded from Finland’s oldest bedrock. These crystals contained radioactive elements older than the parent rock, revealing an even more ancient phase of the bedrock connected to Greenland.

Continents hold long memories due to their lightness of composition compared to oceanic slabs. Continental slabs form when older rock material partially melts and lighter minerals crystallize first before floating on heavier stone material below them for growth and eventual collision with other continents over time. On the other hand, oceanic slabs form when heavy rock material beneath it melts and recrystallizes before sinking back to the earth’s surface over time due to its density compared to continental plates.

The history of marine life is mainly understood through rocks brought from sea to continents due to plate collisions over millions of years or billions for continental memories compared to oceanic memory spanning only around 200 million years since its formation through volcanic activity beneath oceanic plates that melted and recrystallized sinking back into deep water currents forming new basins on earth’s surface bringing back marine life with it as they submerge again into deeper waters creating new habitats for sea creatures such as coral reefs and other marine ecosystems which continue shaping our world today offering glimpses into an ancient past of our planet through ongoing geological processes that never cease or slow down despite human activities impacting them directly or indirectly affecting their behavior patterns leading us towards environmental challenges we face nowadays requiring immediate attention from scientists worldwide working together towards sustainable solutions ensuring future generations can inherit a healthier planet without disrupting its delicate balance caused by human actions that are slowly but surely destroying it little by little every single day if we do not take action soon enough before it is too late!
