Answer:
The sun shines with equal intensity on a farm field, an asphalt road and the ocean. So basically asphalt road are heated the most during the day
Explanation:
The heat of water is more than the specific heat of sand.
Therefore sand is hot.
.Water is reflecting solar radiation.
The land retains more heat since the land absorb solar radiation.
Therefore the land surfaces warm faster.
Since water is a slow conductor of heat, it need more energy than the sand. so its temperature is increasing. soil loses heat faster.
The ocean heats slower than land , the land air is more warmer than lean air. After the sun set the land loses heat quickly .The air above it cools.
