Which way does thermal energy move when a cool breeze moves over a warm lake?

When a cool breeze moves over a warm lake, thermal energy travels from the lake to the cool air.

The term convection refers to a mode of heat transfer in which thermal energy moves form one point to another by the actual movement of the particles of matter. Convection is responsible for land and sea breeze.

Land breeze refers to cool air blowing away from the land towards the sea. Thermal energy travels upwards from the sea warms the surrounding air and a convection current is set up.

Upwards, i.e. from the lake water to the air.

Explanation:

Similar is the situation in case of the land breeze where the land is cooler than the water bodies and the warm air over the water bodies rises up being less denser in the atmosphere and the space above the warmer water body is occupied by the cooler air that blows from the land.

Again this air is also heated up and the cycle continues.
