Where did the continents come from?
Continental Rifting1. Continental drift: The mystery of moving landmasses The origin and movement of continents has long been a subject of fascination and scientific investigation. The theory of continental drift, proposed by Alfred Wegener in the early 20th century, revolutionized our understanding of Earth’s landmasses. According to this theory, the continents were once part of a

Can Continental Collision Halt or Reverse Plate Direction at a Divergent Boundary?
Continental RiftingThe Earth’s lithosphere is composed of tectonic plates that are constantly moving and interacting with each other. At divergent boundaries, two plates move away from each other, resulting in the formation of new crust. The East African Rift System (EARS) is an example of a divergent boundary where the African plate is moving away from

Why continents do not subduct
Continental RiftingAsked by: Veronica Mitchell But here’s the hitch: the reason these fragments smash into the continent instead of sinking into the mantle is that they are too light and thick to subduct. The buoyant crust gets stuck and chokes the subduction zone. Somehow, though, these geologic conveyer belts eventually resume their descent. Do continents ever
