Is there a difference between the thermal difference between sea and land and the difference in ther

The difference in thermal properties between sea and land refers to the difference in properties between ocean and land caused by the difference in specific heat (which can also be considered as different heat capacity) between the ocean and land. The specific heat (heat capacity) of the earth is low and when there is sunlight, the surface temperature rises quickly (the earth being a poor conductor, the interior of the earth receives less heat). When the sun doesn't shine, the surface temperature drops quickly (because it retains less heat and can therefore escape more easily). The ocean has a greater specific heat (heat capacity) because it can transfer heat to the depths of the ocean through the movement of seawater. Therefore, when there is sunlight, the temperature of the ocean surface will not rise very high. When there is no sun, the heatin the depths of the ocean will slowly be transferred to the ocean surface. Therefore, when there is no sun, the ocean temperature. the surface of the ocean will not rise very high, nor too low either.

In this way it is formed that when there is sun, the land surface temperature is high and the ocean surface temperature is low. When there is no sun, the land surface temperature is low and the ocean surface temperature is low. the temperature is high. This difference is the difference in thermal properties between sea and land. Its formation is mainly caused by heat capacity.

The ocean temperature is lower than the land temperature in summer and the temperature is higher than the land temperature in winter due to the difference in thermal properties between the sea and the earth.

In summer, the ocean warms slowly, the lande is warming rapidly and the ocean temperature is low. In other words, the land warms quickly and the ocean warms slowly, resulting in low ocean temperatures and high land temperatures in summer at the same latitude.

This is related to the absorption and dissipation temperature of water and earth. Water absorbs heat slowly and dissipates it slowly, while the opposite is true for land. This phenomenon will occur under the same conditions. This is mainly due to the difference in thermal properties between sea and land. The earth has a low heat capacity, meaning it heats up and cools down quickly. The ocean has a large heat capacity, so it warms and cools slowly. slowly.

The main reason for this phenomenon is that the specific heat capacities of the ocean and the land are different. The earth is warming and cooling rapidlynt, while seawater slowly warms and cools. by the difference in absorption and heat dissipation between them.

Since the specific heat capacity of seawater is greater than that of inland seawater, seawater with large specific heat capacity heats up slowly. In summer, seawater evaporates and absorbs surrounding heat, resulting in the ocean's temperature. is lower than that of land in summer. The specific heat capacity of seawater is large and it warms and cools slowly. This is why coastal areas develop slowly and have a high population density.

Detailed information:

Cause of formation

Summer, land The temperature rises rapidly and the temperature is higher than that of the ocean, thus forming low pressure on the land and high pressure on the ocean. LThe wind blows from the ocean towards the land. In winter, the land cools faster than the ocean. , and the temperature of the earth is lower than that of the ocean.

High atmospheric pressure forms over land and low atmospheric pressure over the ocean. Therefore, the atmospheric pressure over land is higher than the atmospheric pressure over the ocean. Due to atmospheric pressure, wind. blows from the land towards the ocean.

It can be seen that the difference in thermal properties between sea and land causes changes in the direction of winter and summer winds, which leads to the formation of monsoons. The most typical climate is temperate monsoon climate/Subtropical monsoon climate/tropical monsoon climate
