Does slow movements of mantle rock called radiation transfer heat in the mantle?
No, slow movements of mantle rock called convection transfer heat in the mantle. Convection occurs due to the heat generated by the radioactive decay of elements in the mantle causing molten rock to rise and cooler rock to sink in a continuous cycle.
What happen to the crust when the molten rock sink to lower mantle?

Cooler molten rock does what sink or rise?
Cooler molten rock sinks because it is denser than the hotter, less dense molten rock around it. As it cools, it becomes more rigid and eventually solidifies, creating new layers of rock over time.
Explain why cool rock material sink when convection takes place in the mantle?
Cool rock material sinks in the mantle during convection because it becomes denser than the surrounding, hotter rock. As mantle material heats up, it expands and becomes less dense, rising toward the Earth's surface. Conversely, as material cools, it contracts and increases in density, causing it to sink back down. This continuous cycle of rising and sinking creates convection currents that drive the movement of tectonic plates.
What causes convection currents it the mantle?
Convection currents in the mantle are mainly caused by the heat generated from the radioactive decay of elements within the Earth's interior. This heat creates temperature differences in the mantle, causing warmer, less dense rock to rise and cooler, denser rock to sink, driving the movement of mantle material in a continuous cycle.
Why does magma rise toward the crust and not sink into the mantle?
By being less dense than, so slightly buoyant in, the surrounding rock.
How are lava lamp and the earth mantle alike?
Both the lava lamp and the Earth's mantle involve convection currents. In a lava lamp, heated wax rises and cools, creating a circulating motion. Similarly, in the Earth's mantle, heat from the core causes molten rock to rise, cool, and sink back down in a continuous cycle due to convection.
What will happen to the convection currents in the mantle if earth's interior cools down?
Convection currents are transferring heat to the surface through the movement of mantle rock. If the interior of the planet cools, the mantle rock would be too solid to move, and there would be no heat to transfer.
Does The mantle of the earth continually heats up and cools down using convection currents?
Yes, the mantle of the Earth heats up and cools down due to convection currents. Heat from the Earth's core drives convection currents in the mantle, causing hot material to rise and cool material to sink. This movement transfers heat throughout the mantle, driving plate tectonics and volcanic activity.

No, slow movements of mantle rock called convection transfer heat in the mantle. Convection occurs due to the heat generated by the radioactive decay of elements in the mantle causing molten rock to rise and cooler rock to sink in a continuous cycle.

Why does cool rock sink when convection takes place in the mantle?
Cool things always sink (because they are more dense) and hot things always rise (because they are less dense) in convection. It does not matter if it is rock, air, water, metal, wax, oil, etc., convection always works the same.
