During convection, hot material rises due to its lower density, creating a current that transfers heat from the hot material to cooler material. This process then causes the cooler material to sink and cycle back towards the heat source, creating a continuous convection current.
Convection currents in the mantle are caused by heat from the Earth's core. As the core heats up the lower mantle, the material becomes less dense and rises towards the surface. Once the material at the surface cools, it becomes denser and sinks back down, creating a continuous cycle of movement known as convection currents.
Convection currents inside the Earth happens. The part where the convection currents go up, it brings up materials from the mantle like rocks. This forms new crust. When the convection currents go down, it brings down some older, colder oceanic crust to the mantle, destroying it. In conclusion, the crust is formed and destroyed when convection currents inside the Earth happen.

The convection cell turns upward at point A due to the rising of warm air near the Earth's equator. As the warm air rises, it creates a low-pressure system, which causes the air to flow towards the poles at high altitudes. This flow of air completes the convection cell cycle.
The convection cell turns down at point c due to cooling of the air parcel at that elevation. As the air cools, it becomes denser and starts to sink. This sinking motion creates a downward convection flow in the cell.
In a convection cell, warm air rises due to being less dense than cooler air. As the warm air rises, it creates a low-pressure area at the surface, causing cooler air to be drawn in. This cycle of warm air rising and cool air sinking creates the convection cell's overturning motion.
heat from the outer core and the mantle when it drifts up to the asthenosphere it causes convection.

A temperature difference within the fluid and a gravitational force are necessary for a convection cell to be set up. The warmer fluid rises due to lower density, while the cooler fluid sinks due to higher density, creating a circular motion known as a convection cell.
Uneven heating of different air masses causes the bottom ones to heat up, rise, cool off, and fall in another location in a cyclic motion.
