Answer:
Land heats up faster than water because
Land absorbs more radiation from sun than water
Step-by-step explanation:
Specific heat capacity : It is the amount of heat required to raise the temperature of 1 g of substance by 1 degree.
The value of Specific heat capacity for water = 4.2 J/gC
Sand has formula -SiO2- . Its specific heat = 1.0 J/gC
The reasons for more Heating of lands as compared to water surface are :
- The specific heat capacity of water is much more than sand , rock or lands
- Only the topmost layer of the land gets heated whereas the water surfaces allow heating of deep layers also.
- Soil is opaque or dark hence absorb more radiation whereas water is transparent .Water absorb overall less quantity of solar radiation ,where the heat does more deeper.
- water has to loose more energy than sun for decreasing temperature because its specific heat is more .
