How does mantle convection occur
WebMantle convection occurs at rates of centimeters per year, and it takes on the order of hundreds of millions of years to complete a cycle of convection. Neutrino flux measurements from the Earth's core (see kamLAND ) show the source of about two-thirds of the heat in the inner core is the radioactive decay of 40 K , uranium and thorium.

WebMay 6, 2024 · Converging currents drive plates into each other. Diverging currents pull them apart. This is mostly true. Hot mantle rock rises from the core and moves along under the crust until it grows cool and heavy and sinks back down again. But the plates … WebSep 12, 2024 · A temperature difference leads to an energy transfer from an area of higher energy to one of lower energy. Convection is a heat transfer process. When currents are produced, matter is moved from one location to another. So this is also a mass transfer process. Convection that occurs naturally is called natural convection or free convection.
