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.

which diagram correctly indicates why convection currents form in water when water is heated
the layer that has convection currents is the mantle
Convection currents
They travels in the form of waves and are filtered through the Earth's atmosphere.
what produces convection currents in earth's atmosphere
Solar energy
Wind.
Both convection currents in the ocean and atmosphere are driven by temperature differences. In the ocean, warm water rises and cold water sinks, creating circular currents. Similarly, in the atmosphere, warm air rises and cool air sinks, generating vertical movement of air masses. Both types of convection currents play a crucial role in redistributing heat around the 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.
Hot air rises and displaces cooler air, creating convection currents in the atmosphere.
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.
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.
Convection currents can be found in real-world examples such as in the atmosphere, where they drive weather patterns and wind movements. In the ocean, convection currents play a role in the circulation of water and nutrient distribution. In the Earth's mantle, convection currents are responsible for the movement of tectonic plates and the formation of volcanic activity.

From the surface, it would be via convection currents
cold air is less dense
