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 .
