Convection currents and plate movement - BBC Bitesize

WebConvection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth. WebConvection currents rise and spread below divergent plate boundaries and converge and descend along convergent. The convection currents are sought to be produced by … ina garten roasted broccoli with lemon https://mimounted.com

What is the role of convection currents in plate movement?

WebEarthquakes and volcanoes are concentrated at the boundaries between lithospheric plates. It is thought that plate movement is caused by convection currents in the mantle (Fig. 2), although the exact mechanism is not known. Lithosphere plates are moving at rates of a few cm per year. WebA convection current is a process that involves the movement of energy from one place to another. It is also called convection heat transfer. What is the reason that makes you feel hotter when placing your hands above a …

Web21 aug. 2024 · Which statement explains how convection currents affect the movement of plates? A.)Gravity pulls one edge of a plate down into the mantle, which causes the rest of the plate to move as well. B.)Heat from Earth’s interior causes lithospheric plates to collide at convergent plate boundaries, causing volcanoes. Web12 dec. 2024 · UPDATED (Jan, 2024) - New Ending On Convection Lithospheric plates are part of a planetary scale thermal convection system. The energy source for plate tectonics is Earth’s internal heat while the forces moving the plates are the “ridge push” and “slab pull” gravity forces.

Web1 mrt. 2024 · Mantle convection describes the movement of the mantle as it transfers heat from the white-hot core to the brittle lithosphere. The mantle is heated from below, …

WebWhen a divergent boundary occurs beneath oceanic lithosphere, the rising convection current below lifts the lithosphere, producing a mid-ocean ridge. Extensional forces stretch the lithosphere and produce a deep fissure.
