One of the most puzzling phenomena lies beneath the Indian Ocean, south of Sri Lanka, where a massive gravity anomaly known as the Indian Ocean Geoid Low (IOGL) has confounded researchers for decades, ...
Iron monoxide may act as a heat conductor from Earth’s core, affecting tectonic and volcanic activities on the surface. This discovery sheds light on the deep mantle’s properties and their impact on ...
They examined the chemistry of 3,983 samples from midocean ridges, where the tectonic plates are spreading apart and magma from the shallow mantle is oozing and hardening into volcanic rock ...
as modern imaging techniques have not been able to identify convection currents within the mantle that are large enough to move tectonic plates. As a result this theory has been largely discredited.
There are three types of convergence. Our first type of convergence is continental vs continental. When two continental plates collide they cannot sink into the mantle, so there is no subduction.
