An example of convection in the Earth's system is the movement of magma within the Earth's mantle. As the hot magma rises due to its lower density, it cools and eventually sinks back down. This continuous cycle of rising and sinking magma is known as mantle convection, playing a significant role in the movement of tectonic plates and shaping the Earth's surface.
An example of convection in the Earth system is the movement of mantle material in the Earth's interior through the process of mantle convection. This movement of hot rock material creates the slow, continuous flow of mantle material that drives tectonic plate movements on the Earth's surface.

Convection
An example of convection in Earth's atmosphere is the formation of thunderstorms. Warm air near the surface rises due to its lower density, carrying moisture and energy upwards. As the air reaches higher altitudes, it cools and condenses, leading to the formation of towering cumulonimbus clouds and eventually thunderstorms.
An example of convection in Earth's surface is the movement of tectonic plates. Heat from the Earth's interior causes the molten rock in the mantle to rise towards the surface, where it cools and sinks back down. This convection process drives the movement of the tectonic plates, leading to phenomena like earthquakes and volcanic activity.

Convection currents can vary in thickness, typically ranging from a few centimeters to kilometers depending on the scale of the system in which they occur. In the Earth's mantle, for example, convection currents can be tens to hundreds of kilometers thick.

The heating alone is not, no, but the convection it sets up, thus forming winds and weather systems, is a valid example.
One example of where energy transfer by convection occurs is in the Earth's atmosphere. Heat from the sun warms the air near the Earth's surface, causing it to rise and transfer heat to higher altitudes through convection currents.

Radiation, Conduction, and Convection.
Objects that contain fluids, such as air or water, can exhibit convection. For example, a pot of boiling water on a stove or a convection oven uses this process to transfer heat. Additionally, the Earth's atmosphere and oceans also experience convection.
No, radiation from the sun heats the Earth primarily through the process of absorption of solar radiation by the Earth's surface and atmosphere. Convection is the transfer of heat through the movement of fluids, such as air and water, but it is not the primary mechanism by which the Earth is heated by solar radiation.
