The Convection Cycle
it is called a cycle because it is a continuous process.
the rock cycle
The cycle of heating, rising, cooling, and sinking of magma is called mantle convection. This process drives the movement of tectonic plates and is a key mechanism in the geological activity of the Earth. As magma heats up, it becomes less dense and rises, while cooler, denser magma sinks, creating a continuous cycle that influences volcanic activity and the formation of landforms.
Horologic cycle is the continuous rotation of water. Horologic cycle is also known to be called a water cycle.
The cycle of heating, rising, cooling, and sinking is called a convection current. This process occurs in fluids, such as air and water, where warmer, less dense material rises while cooler, denser material sinks, creating a continuous flow. Convection currents are fundamental in various natural phenomena, including weather patterns and ocean currents.
this is called convection current
The convection / subduction cycle.
The rock cycle.
Igneous rocks form from the cooling and solidification of magma or lava. These rocks can then be weathered, eroded, and transported by natural processes like wind and water. Eventually, they may be buried, metamorphosed, and melted again to form new igneous rocks in a continuous cycle called the rock cycle.
The Carnot cycle is an idealized thermodynamic cycle that describes a perfect heat engine. In the Refrigeration system we need cooling effect.so it has to operate in opposite nature to produce the cooling effect. So we run the catnot cycle reversly in the refrigeration system. So we call the Refrigeration cycle called as REVERSED CARNOT CYCLE.
cycle is not exactly the correct term, but it is continuous.
it is called the water cycle
