What three factors set convection currents in motion?
Answer (3)
The three factors that set convection currents in motion are: the heating and cooling of fluid, change in its density, and the force of gravity combine to set it in motion.
The difference in temperature between the two fluid components allows the heat energy to be transported by convection. Hot fluids have a tendency to ascend due to this temperature difference, whereas cold fluids have a tendency to sink.
What is temperature?
Temperature is a physical quantity that expresses the hotness of matter or radiation. Temperature is measured with a thermometer.
Convection causes temperature disparities by forcing portions of a liquid or gas to heat up or cool down faster than their surrounds. The hotter , less dense, and cooler, denser, areas then drive the areas to migrate as a result of these temperature differences.
Convection , often known as a heat transfer mechanism, is a method of moving heat. When a fluid, such as air or water, is moving, this heat transfer takes place. Temperature differences within the fluid cause convection .

The heat source for these currents is heat from Earth's core and from the mantle itself.
Hot columns of mantle material rise slowly.

Convection currents are set in motion by temperature differences, density changes, and the force of gravity. The warmer, less dense fluid rises while cooler, denser fluid sinks, creating a cycle of movement. Gravity facilitates this process by acting on the different fluid densities.
