density
Differences in a materials __________ is what drives convection
No Density also drives convection.
An example of convection in the Earth system is the movement of mantle material in the Earth's interior through the process of mantle convection. This movement of hot rock material creates the slow, continuous flow of mantle material that drives tectonic plate movements on the Earth's surface.
The term for the circular movement of material inside Earth's mantle is convection. Heat from Earth's core causes hot material to rise, while cooler material sinks, creating a continuous, circular flow that drives plate tectonics.
The heat source that drives convection currents inside the Earth is primarily from the decay of radioactive elements within the Earth's core. This heat causes the material in the mantle to become less dense and rise, creating convection currents that drive the movement of tectonic plates.
Convection is the transfer of heat through the movement of fluids such as air or water. It occurs in Earth's layers, specifically in the mantle, through the process of mantle convection. This movement of hot, less dense material and cooler, denser material in the mantle drives the motion of tectonic plates on the Earth's surface.
Density
The heat that drives convection currents in the mantle primarily comes from the radioactive decay of elements such as uranium, thorium, and potassium. This heat causes the mantle material to become less dense, rise towards the surface, cool down, then sink back towards the core in a continuous cycle of convection.
Convection Current
Convection
Convection in the mantle drives the movement of tectonic plates. As hot material rises and cooler material sinks in the mantle, it creates circulation patterns that push and pull the overlying tectonic plates. This convection process is a key driving force behind plate tectonics and the movement of Earth's lithosphere.
When heat is removed from the fluid, the temperature of the fluid will decrease, causing the convection currents to slow down or even stop. This is because the temperature difference that drives the convection process will decrease, leading to a reduction in the movement of the fluid particles.
