How Earth Recycled a Mountain Range

The video explains the geological history of the Adirondack Mountains, highlighting the formation and uplift of ancient rocks. It discusses the billion-year-old anorthosite rock and the Grenville Orogeny event, which created a massive mountain range. Over time, erosion and sedimentation led to the formation of a shallow ocean. The video explores how the Adirondack Mountains were uplifted without new continental plate collisions, possibly due to buoyant rock and heat expansion. The process continues today, revealing ancient rocks as newer sediments erode.
