North America's 'broken heart': The billion-year-old scar from when the continent nearly ripped apart The Midcontinent Rift is a giant tear that formed in what is now the U.S. Midwest 1.1 billion years ago. Nicknamed North America's "broken heart," it is filled with solidified magma and lava.

About 1.1 billion years ago, tectonic forces nearly split North America from Kansas to Michigan. Though the rift failed, it left a deep scar beneath the Midwest that helps scientists understand how continents evolve.

Was watching a YouTube video from GeoGirl about oldest rocks she reminded me the every time I see a video of the continents shifting I wish the cratons were highlighted. It would help so much. Also the sea levels never fluctuate #continentaldrift #platetectonics #cratons #geology

Venus' 'continents' suggest surprising link to early Earth New research has revealed that Venus, often considered Earth's inhospitable twin, may share a surprising geological history with our own planet.

The Venusian highlands as proto-continents (similar to the cratons of the Earths continents), once again shown to be a viable idea. Supports the idea that both planets were initially on similar paths which then diverged. Neat! But unfortunately, no preprint available. #venus #cratons #tesserae
