Convection occurs in the asthenosphere due to heat generated in Earth’s core. This heat drives convection currents throughout the mantle because magma is able to move as a viscous fluid rising and turning over again as it is heated from below.

What causes convection in the atmosphere?
Convection currents are created in the Earth's atmosphere as the sun heats the gases, causing them to rise. Theses gases cool as they rise high into the atmosphere and travel back down towards the ground to get heated again.
What causes the convection currents how do they form?
Convection currents form because a heated fluid expands, becoming less dense. The less-dense heated fluid rises away from the heat source. As it rises, it pulls cooler fluid down to replace it. This fluid in turn is heated, rises and pulls down more cool fluid.
What are three causes of convection?
- heating and cooling of the fluid. - changes in the fluid's density and. - force of gravity. - The heat source for these currents is heat from Earth's core and from the mantle itself. - Hot columns of mantle material rise slowly.

What are the factors that cause convection?
Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.
What are two factors that cause convection?
- heating and cooling of the fluid. - changes in the fluid's density and. - force of gravity. - The heat source for these currents is heat from Earth's core and from the mantle itself. - Hot columns of mantle material rise slowly.
What causes convection currents in the atmosphere?
Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.

What causes convection in the atmosphere quizlet?
Convection is heat transfer by the movement of currents with in a fluid. It is caused by the difference in temperature and density.
What 2 properties cause a convection current to occur?
What Causes Convection Currents? The uneven heating of a fluid causes convection currents. As the fluid is heated, it becomes less dense and rises. The change in density is caused by the molecules of the fluid moving faster and further apart.

What is needed for a convection current to occur?
Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.
