Detailed Solution

The matrix is based on the effects of uneven temperatures and measuring them.
Land breeze occurs during the nighttime because, during the nighttime, the land gets cooled faster than the sea, and the warm air above the sea rises. Thus the cold air from the land flows towards the sea, causing a land breeze.
Sea breeze occurs during the daytime because, during the daytime, the land gets heated up faster than the sea, and the warm air above the land rises. Thus the cold air from the sea flows towards the land, causing a sea breeze.
Dark-coloured surfaces are good absorbers and radiators of heat.
The colour of any object is the light it reflects. A white object reflects all the light that falls on it. Black objects do not emit or reflect light in any part of the visible spectrum. Instead, they absorb all such frequencies of light.
On the other hand, white surfaces do not absorb radiation. Since the white surface does not absorb radiation, then it will reflect the radiation. So the white surface is a poor absorber and poor emitter. Therefore, white surfaces are good reflectors. Hence, a white surface is a poor absorber and a good reflector.
A thermometer is used to measure the temperature of an object/body.
