Until now, the answer was thought to be unrest in Earth’s mantle. Under intense heat and pressure, superheated magma rises in what are known as convection currents, pushing the tectonic plates ...

New research has uncovered a fascinating link between volcanic eruptions and mysterious structures deep within Earth’s interior, challenging long-standing assumptions about the planet’s lower mantle.

are where tectonic plates pull apart due to convection currents in the mantle. Most constructive plate boundaries are found on ocean floors. As the plates move apart (very slowly), magma ...

Previous theories have suggested that the movement of these tectonic plates is likely caused by convection currents in the molten rock in Earth's mantle below the crust. This idea would explain ...

New simulations reveal a hidden “ocean of fire” that once existed above Earth’s core, influencing the planet’s internal landscape. These ancient molten seas, known as the basal magma ocean, were a ...

Here convection currents push mantle material together, forming plumes of less dense rock that eventually will start rising and heating up regions of the mantle.

They are thought to move around by convection currents in the mantle, but whether those currents exist in the whole mantle or just the upper part is still an open question, Murthy said.

ROANOKE, Va. (WDBJ) - Our favorite scientists from the Science Museum of Western Virginia dropped by 7@four to talk about convection currents. Danielle Murray and Brooke Haas joined us.
