Solar heating of the Earth's surface (land or water) heats the air above it, which becomes less dense that the air above it, and is displaced (rises). Once at higher altitudes, the air cools and sinks. The largest convection process transports heat and water vapor poleward from the tropics.
When air is heated, it becomes less dense than the cooler air above it, and rises (is displaced). As it moves upward, it is cooled, and the adiabatic pressure around it is lower, so it sinks again. Where water vapor is included in the air, this can create a phase change to liquid (clouds) at higher altitudes.
Convection is a mechanically or thermally produced process involving upward or downward transfer of part of the atmosphere.

Convection take place because of convection currents
Which best explains the relationship between ocean currents and convection currents?(1 point) Responses Convection currents join with the Coriolis effect to create the winds that drive ocean currents. Convection currents join with the Coriolis effect to create the winds that drive ocean currents. Ocean currents rely on warm convection currents to strength the Coriolis effect. Ocean currents rely on warm convection currents to strength the Coriolis effect. Ocean currents create a Coriolis effect that increases convection currents. Ocean currents create a Coriolis effect that increases convection currents. Convection currents use the Coriolis effect to generate ocean currents.
In what two places do convection currents form when the Sun heats Earth
Vertical convection in both the ocean and atmosphere is caused by uneven HEATing.The source of energy for convection in the ocean and atmosphere is heating from the sun.
Warm air rising and cold air sinking in combination with the rotation of the Earth cause the various currents in the atmosphere.
Lighter, warm material rises while more heavier, cool material sinks. It is the movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth. In the atmosphere, as air warms it rises, allowing cooler air to flow in underneath.
cold air is less dense
