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 campfire or when sitting next to it? Or, why is the movement of liquid so rapid when water is boiled in a pot? Web6 sep. 2016 · Convection currents is related to plate tectonics because it explains the reason why plate tectonics move. Explanation: For instance, some geologists believe that the main factor for the motion of plate tectonics is convection currents that occurs in the mantle. This is because the mantle is made of semi-molten rock called magma.
Web22 jul. 2024 · Convection 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. WebA visual representation of what is happening to cause plate movement but the convection of the mantle below the earth's crust
Mantle convection is the very slow creeping motion of Earth's solid silicate mantle as convection currents carry heat from the interior to the planet's surface. The Earth's surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle. The lithosphere is divided into a number of tectonic plates that are continuously being created or consumed at plate boundaries. Accretion occurs as mantle is added to the gro… WebThe hypothesis of convection currents suggests that flow in the mantle is induced by currents which drag and move the lithospheric plates above the asthenosphere. Convection currents rise and spread below divergent plate boundaries and converge and descend along convergent.
