What’s difference in temperature of land & sea & temperature on land different from that of oceans even though both receive same amount of insolation?
Land surfaces absorb much more solar radiation than water. Water reflects most solar radiation that reaches its surface back to the atmosphere. Since land absorbs more solar radiation the land surface retains more heat as do the vegetation for energy. Thus, land surfaces warm more quickly than water. Water has about four times higher heat capacity than land, i.e. it takes much more energy to increase the water temperature and the water temperature will therefore respond slower to temperature changes. Compared to land, the sea gets heated slowly and loses heat slowly. Land heats up and cools down quickly. Therefore, the variation in temperature over the sea is less compared to land
The temperature on land different from that of oceans even through both receive the same amount of heat is due to sea breeze and absorption rate of land. There are two reasons: Sea breeze the warm air from Oceans travel towards land and this happens in summer and spring season.Compared to land, the sea gets heated slowly and loses heat slowly. Land heats up and cools down quickly. Therefore, the variation in temperature over the sea is less compared to land. At high latitudes, ocean waters receive less sunlight – the poles receive only 40 percent of the heat that the equator does. These variations in solar energy mean that the ocean surface can vary in temperature from a warm 30°C (86°F) in the tropics to a very cold -2°C (28°F) near the poles. Water has about four times higher heat capacity than land, i.e. it takes much more energy to increase the water temperature and the water temperature will therefore respond slower to temperature changes. It takes less energy to change the temperature of land compared to water. This means that land heats and cools more quickly than water and this difference affects the climate of different areas on Earth.Water gets colder with depth because cold, salty ocean water sinks to the bottom of the ocean basins below the less dense warmer water near the surface. Land changes temperature faster than water does. Therefore, as the sun shines and begins to heat the Earth's surface, the land's temperature increases faster than the water's temperature. This leads to a temperature difference between the land and the water. The temperature of the air is caused by the combination of air, water, and land working together. Those three factors heat and cool areas at different rates. Temperature also varies by the time of day, the season, or even the year. When weather people talk about temperature, they are talking about a mean temperature. There are differences in climate around the world because of differing amounts of radiation received from the Sun at different parts of the Earth at different times of the year. More heat from the Sun is received near the equator than near the north and south poles where the angle of the Sun's rays is lower.

The temperature on land different from that of oceans even through both receive the same amount of heat is due to sea breeze and absorption rate of land. Explanation: There are two reasons: Sea breeze - the warm air from Oceans travel towards land and this happens in summer and spring season. Compared to land, the sea gets heated slowly and loses heat slowly. Land heats up and cools down quickly. Therefore, the variation in temperature over the sea is less compared to land.At high latitudes, ocean waters receive less sunlight – the poles receive only 40 percent of the heat that the equator does. These variations in solar energy mean that the ocean surface can vary in temperature from a warm 30°C in the tropics to a very cold -2°C near the poles. Specific Heat of water is more than land earth. Therefore for given heat change in temp. of land is more than ocean water.For a given amount of water and soil, if the soil requires less heat to raise the temperature by 1∘ C, it means that it has low specific heat capacity than water. Thus, the temperature of land rises faster than that of the sea because the specific heat of soil is lesser than water. Global warming the average increase in land as well as sea surface temperature is primarily due to the increase in greenhouse gases from human activities. Rising land surface temperatures affect glaciers, ice sheets, permafrost, and the vegetation in Earth's ecosystems. During the day, the land surface heats up faster than the water surface. Therefore, the air above the land is warmer than the air above the ocean. During the day, the land surface heats up faster than the water surface. Therefore, the air above the land is warmer than the air above the ocean. Now, recall that warmer air is lighter than cooler air.
