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. Problem: Does land or water warm faster?
In the case of sunlight being the heat source the simple answer is that soil is darker than water and thus absorbs more light and heats up faster. Importantly, water has a higher specific heat, meaning it takes more heat input to cause an increase in the substances temperature, which explains this phenomenon in most other cases.
No, water does not heat up or cool down faster than soil. This is because soil has lower specific heat. Specific heat is how long it takes for a substance to heat up or cool down.
As a result, it takes up to four times the amount of heat to raise the temperature of a given amount of water 1 C as it takes to raise the temperature of the same amount of land by an equivalent degree. Color is also a factor. Because water is lighter than land, it reflects more solar radiation and does not heat as quickly.
Soil will lose heat faster than water. This depends on the specific heat of the two substances you are comparing. Specific heat of a substance is the amount of energy required to raise its ...
Water will still heat slower than olive oil when placed in the microwave, but your graphs should have indicated that water heats up faster in the microwave than it does on the hot plate. Why? For both the hot plate and the microwave, olive oil will heat up faster than water because the heat capacity of oil is lower than the heat capacity of water.
Firstly, land (basically soil or even rock) is not a good conductor of heat, secondly specific heat and thus heat capacity of the land or soil is far too low as compared with that of water and thirdly the only means of transfer of heat inner layers of land to its outer most layer is conduction whereas surface of the land can loose heat by way of (a) radiation and (b) transfer by contact to air ...
However, you have to consider that it takes a lot more energy to heat a gram of water than to heat a gram of soil minerals. The specific heat is the calories it takes to raise the temperature of 1 gram of a substance 1 degree Celsius. The specific heat of water is one of the highest at 1 calorie per gram.
Additionally the oceans retain heat longer. The Sun's rays also penetrate the oceans to a depth of many meters, but only heat up the top layer of the sand or soil. Water has to lose more energy than the sand (dry land) in order for the temperature to decrease.
Why Does Sand Cool Down Faster Than Water? Sand cools down faster than water because it has a lower specific heat capacity than water. That is, it takes more energy to raise the temperature of water than to raise the temperature of sand by the same amount, given equal masses of each substance.
