- Water is slower to change temperature than dry land, which means that sometimes oceans will be warmer than the surrounding land, and sometimes cooler. The air over the oceans or the land reflect their tempreatures, so masses of cold and warm air form.s a result, land heats up faster in the day and cools  down more slowly at night than water does. For this reason, air  over land tends to be warmer in the day an cooler at night than air  over water. + 3 others found this useful. Awais Ali.

- In contrast, cold water currents cool the air above them and since cold air has less of an ability to hold moisture than warm air, these currents tend to bring cool, dry weather to adjacent land areas. Fog is often found along the land-sea borders where cold ocean currents exist.n contrast, cold water currents cool the air above them and since cold air has less of an ability to hold moisture than warm air, these currents tend to bring cool, dry weather to adjacent land areas.

- The thermocline starts at the beginning of the summer at a relatively shallow depth with little temperature difference across it. As the summer progresses, however, and more surface water is heated, the thermocline's temperature difference and depth both increase.The bottom water warms slightly due to heat transfer from the above waters, but overall the bottom water is less affected.owever, the statement that the water below a thermocline is always clearer than the top water is not always true. Oxygen-poor bottom water can kill a lot of the fish and mussel life, then anaerobic bacteria start thriving and can perversely cause the bottom water to have less visibility than the top water.

Classroom activity:Differential Heating and Cooling of Land and Ocean Teacher Background. All you need to do on a sunny day is walk on a dry beach in the early afternoon to learn that the sand can get very much warmer than sea water. 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.

The Air Around Us Land loses heat faster than water. So at night, the air over land cools off more than does the air over water. Land also heats up faster than water. So during the day, the air over land is heated more than is the air over water. Thus land and water are heated unevenly.

Water Temperature The solubility of oxygen and other gases will decrease as temperature increases 9. This means that colder lakes and streams can hold more dissolved oxygen than warmer waters. If water is too warm, it will not hold enough oxygen for aquatic organisms to survive.emperature is an important factor to consider when assessing water quality. In addition to its own effects, temperature influences several other parameters and can alter the physical and chemical properties of water.

Density of Ocean Water There are two main factors that make ocean water more or less dense than about 1027 kg/m 3: the temperature of the water and the salinity of the water. Ocean water gets more dense as temperature goes down. So, the colder the water, the more dense it is. Increasing salinity also increases the density of sea water. Less dense water floats on top of more dense water. Given two layers of water with the same salinity, the warmer water will float on top of the colder water.

- Unequal heating of air over land and water results in breezes near shorelines. While the land is warm during the day, air above it rises, and a cool breeze blows in from the sea.As the land cools off at night, air pressure over it increases, and a cool land breeze blows out to the sea. Examine the changing temperature of the land throughout the 24 hours represented in the animation.s the land cools off at night, air pressure over it increases, and a cool land breeze blows out to the sea.

Sea breeze At night, the land cools off faster than the ocean due to differences in their heat capacity, which forces the dying of the daytime sea breeze as the temperature of the land approaches that of the ocean.

- Now the land's temperature may fall to 55° F, while the water is still 65°. But the same principles apply day or night--air flows from a cooler to a warmer region--though now the direction is reversed. The wind blows from the land to the ocean.

How does the proximity to water affect our weather? The specific heat of water is more than the soil and therefore the water surface requires more heat to raise its temperature.The heating effect of solar radiation penetrates to a considerable depth under the water surface and hence the air above the water surface does not get heated much.Moreover,part of the solar radiation is utilized in ...

How Does Climate Change Affect the Temperature in a Deciduous Forest? Due to the higher temperatures, deciduous forests in some areas are receiving more rainfall than they used to and others are receiving less. On the whole, climate change is causing dry regions to get drier and wet areas to turn wetter. Also, precipitation is tending to fall in heavier bursts -- that is, gaps between periods of measurable precipitation may be lengthier, but when it rains, it pours.

The Water Cycle: Evaporation Evaporation is more prevalent over the oceans than precipitation, while over the land, precipitation routinely exceeds evaporation. Most of the water that evaporates from the oceans falls back into the oceans as precipitation.

Unit 4: Temperature-Moisture Relationship In any one stationary parcel of air, the dew point of that air will remain the same as will the amount of moisture in that parcel, regardless of air temperature. But as air temperature increases, so will the capacity of that air to hold more water vapor. The higher the air temperature, the stronger the bond between water and air molecules, and the drier the air seems to be.

Lapse Rate, Moisture, Clouds and Thunderstorms. The air over land is heated as well, and rises in the atmosphere. At the same time, cooler air from the sea moves to replace the rising warm air. This is because the rising, warmer air leaves the land and creates an area of low air pressure, while air over the sea is in an area of higher air pressure. <br /> Simultaneously, the warm air from the land cools and drops away from the land. <br /> This air raises the air pressure over the sea.

- Three major factors influence salinity (salt concentration) in Pacific Ocean waters: precipitation, evaporation and winds. Precipitation brings freshwater into the ocean, diluting its salt concentration. The rate of evaporation from the ocean s surface waters is also important because it removes water molecules, leaving the salt behind. In regions where the evaporation is high, due to winds and high temperatures, the concentration of salt in the water increases. As a result, areas of water exposed to the strong trade-winds generally have higher salinity values. The salinity of ocean water is measured in parts per thousand. High salinity values are over 35 parts per thousand, while values below this are considered low. Around the equator, where there is large amounts of rainfall, surface salinity rarely exceeds 34 parts per thousand.

- As a result during day time the land temperature is higher than that of sea, and at nights the sea temperature is higher than that of land. Due to this temperature difference between sea and land, during the day time atmospheric air above land expand more than that above sea.his results in air pressure above land becoming less than that above sea, causing cool air from the sea to blow towards land. At night the temperature of land being lower than that of water. the breeze blows from land to sea.

- The warm air over the land is less dense and begins to rise. Low pressure is created. The air pressure over the water is higher with cold dense air, which moves to occupy the space created over the land. The cool air that comes along is called a sea breeze. In the night, the reverse happens. The land quickly loses its’ heat whiles the water retains its’ warmth. This means the air over the water is warmer, less dense and begins to rise. Low pressure is created over the water.
