Convection is the transfer of heat by the movement of a fluid, such as air or water. In the context of land, convection helps explain how heat from the ground is transferred to the atmosphere, leading to differences in temperature between the land surface and the air above it. This temperature difference is responsible for the movement of air masses and the formation of weather systems over land.
Convection
In a convection cell on Earth, heat from the underlying hot material causes it to rise towards the surface, carrying heat energy with it. As this hot material reaches the surface, it cools down and then sinks back down due to its increased density, completing the convection loop. This process of rising and sinking creates a circular motion of heat transfer known as a convection cell.
A person at the beach might feel cooler air coming from the ocean during the day as the warmer air over the land rises and draws in the cooler ocean breeze. At night, the opposite may occur, with warmer air moving from the land towards the cooler ocean. This circulation of air due to temperature differences is what creates convection currents in the atmosphere.

Land breezes and sea breezes are caused by the differential heating and cooling of land and water. During the day, land heats up faster than water, creating a low-pressure area over the land that draws in cooler air from the sea, resulting in a sea breeze. At night, the process reverses, leading to a land breeze. Convection currents are caused by the uneven heating of the Earth's surface, which leads to the rising of warm air and the sinking of cool air, creating a continuous cycle.
I think the land is heated by radiation
it is called convection

Friction creates heat - heat travels by convection, conduction or radiation.
