What causes land breezes sea breezes and convection currents?

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.
