The convection current can't form if heated at the top because then, the hot air would just keep getting hotter; no air moves around.

How are currents that form in heated air similar to currents that form in heated water?

Both air and water currents that form due to heating are driven by a combination of density differences and convection. As the air or water is heated, it becomes less dense and rises, causing a flow of cooler, denser fluid to move in to replace it. This sets up a continual circulation pattern as the fluid cools, sinks, gets reheated, and rises again.


Where do you find convection currents?

Convection currents occur in the asthenosphere.


In what two places do convection currents form when the Sun heats Earth?

Convection currents form in the atmosphere and oceans when the Sun heats the Earth. As the air and water near the Earth's surface warm up, they become less dense and rise, creating a circulation pattern where cooler air or water replaces them.


Which of the folling can form in the geosphere and carry heat from earth mantle toward the surface conduction currents infared currents convection currents or surface currents?

Convection currents are the ones that can form in the geosphere and carry heat from the Earth's mantle towards the surface. These currents move molten rock in the mantle due to differences in temperature and density, driving the movement of tectonic plates and influencing volcanic activity.


Convection currents form when air temperatures are?

Convection currents form when there are temperature differences in the air. Warm air rises because it is less dense than cold air and creates a circular flow pattern. This process helps distribute heat and maintain equilibrium in the atmosphere.

What currents can form when liquids and gases are heated?

When liquids and gases are heated, they can create convection currents. In liquids, heated areas become less dense and rise, while cooler areas sink, creating a circular flow. In gases, heated air rises and cooler air sinks, generating vertical movements that mix and distribute heat.


The circular motion of liquids or gases due to density differences while undergoing convection is known as a convection current The transfer of what form of energy leads to convection currents?

The transfer of heat energy is what leads to the formation of convection currents in liquids or gases. As a fluid is heated, it becomes less dense and rises, while the cooler, denser fluid sinks. This continuous cycle of rising and sinking creates a circular motion within the fluid, resulting in convection currents.


What should the air temperature be for the convection currents to form?

has to be cold


What type of currents form as hot and cool portion of a liquid or gas move?

Convection currents.


Where do you find convection currents?

Convection currents occur in the asthenosphere.


What do convection currents form?

because of differences in pressure and density in a fluid


The transfer of what form of energy leads to convection currents?

Heat Energy


What causes convection currents to form in Earth's atmosphere?

Solar energy


What form of energy leads to convection currents?

the form of energy would be heat. convection currents are caused by uneven heating of air or fluid. The warmer fluid is more boyant than the cooler fluid, so it floats to the top, and creates a "convection current"
