Water is a slow conductor of heat, thus it needs to gain more energy than the sand or dry land in order for its temperature to increase. Water has to lose more energy than the sand (dry land) in order for the temperature to decrease. During the summer the land is much warmer than the water.
Q. What happen to the temperature of water inside the glass?
Answer. Answer: If you pour cold water into a glass on room temperature, nothing will happen. The glass will shatter.

Q. How does the uneven heating of land and water lead to wind?
Solar heating of the Earth’s surface is uneven because land heats faster than water, and this causes air to warm, expand and rise over land while it cools and sinks over the cooler water surfaces. Wind is the result of pressure changes in the atmosphere.
Q. Why does the sun feel hotter at the beach?
When the humidity is at its highest, even a nice breeze won’t aid in evaporation. The result is that your body can’t cool down by sweating and you feel hotter than the temperature around you.
Q. Is Sand hotter than water?
Sand has much lower specific heat than water. A low specific heat means sand doesn’t need much energy from the sun to warm. That’s why when the sun comes out in the middle of the day, sand goes from comfortable to hot quickly.
Q. Why do I only get sunburnt at the beach?
People at a tropical beach vacation are at an increased risk of getting a sunburn because these destinations are nearer to the equator, where the sun’s rays are the strongest. Reflection from the sand and water increases the amount of sun you get.
Q. Why is sand hotter than water at the beach?
The sand should both heat and cool faster than the water. This is because water has a higher specific heat ca- pacity than sand – meaning that it takes a lot of heat, or energy, to raise the temperature of water one degree, whereas it takes comparatively little energy to change the temperature of sand by one degree.
