Divergent plate boundaries are locations where plates are moving away from one another. This occurs above rising convection currents. The rising current pushes up on the bottom of the lithosphere, lifting it and flowing laterally beneath it. This lateral flow causes the plate material above to be...

Examples of divergent plate boundaries include: Separation of the North American Plate from the Eurasian Plate to form the Mid-Atlantic Ridge Separation of the North American and Eurasian Plates through Iceland which forms active volcanos What landforms are created by divergent boundaries? Th...

The coexistence of divergent (spreading ridge) and convergent (subduction zone) plate boundaries at which lithosphere is respectively generated and destroyed is the hallmark of plate tectonics. Here, we document temporally- and spatially-associated Neoar
The presence of offsets, appearing at intervals ranging from 10s to 100s of kilometres, is a distinct characteristic of constructive tectonic plate margins. By comparison, boundaries associated with subduction exhibit uninterrupted continuity. Here, we p
The study of mid-ocean ridges helped establish the theory of plate tectonics in the 1960s. Geomagnetic mapping showed large, alternating "magnetic stripes" in the seafloor, a result ofEarth's ever-changing paleomagnetism. These stripes mirrored each other on both sides of divergent boundaries, giv...
Q1.1: How is the activity at convergent plate boundaries different to that at divergent plate boundaries. Q1.2: What type of activity occurs at transform plate boundaries? Q1.3: Why is Iceland a prominent location for geological research and exploration?Q1.4: How are the movements of plates con...
