As a domain expert in the field of environmental science, I am well-versed in the dynamics of heat transfer between different mediums. When it comes to the question of which heats up more quickly, water or land, several factors come into play, including the specific heat capacity of the materials involved, the color and texture of the surface, and the presence of any reflective properties.
Specific Heat Capacity: The specific heat capacity of a substance is the amount of heat required to raise the temperature of one unit mass of the substance by one degree Celsius. Water has a high specific heat capacity, approximately 4.18 joules per gram per degree Celsius. This means that water can absorb a large amount of heat without its temperature changing significantly. In contrast, the specific heat capacity of soil and rock is much lower, generally around 0.84 joules per gram per degree Celsius. Therefore, for the same amount of heat absorbed, the temperature of land will increase more rapidly than that of water.
Solar Radiation Absorption: Land surfaces, being generally darker than water, absorb more solar radiation. Dark colors are more efficient at absorbing light and converting it into heat. Additionally, water has a reflective quality that sends much of the solar radiation back into the atmosphere, which reduces the amount of heat absorbed compared to land.
Heat Distribution: Water, due to its fluid nature, can distribute heat more evenly through convection currents. This means that even if the surface of the water heats up, the heat can be quickly spread throughout the body of water, reducing the overall temperature rise. Land, on the other hand, does not have this mechanism and heat tends to be more localized, leading to a quicker temperature increase at the surface.
Evaporation and Conduction: Water also has a high heat of vaporization, which means it can absorb a lot of heat during the phase change from liquid to gas without a significant increase in temperature. This process of evaporation cools the surface of the water. In contrast, land does not have this cooling effect and heat is conducted into the ground, raising its temperature.
In conclusion, while land surfaces do absorb more solar radiation due to their darker color and lower reflectivity, water's high specific heat capacity, ability to distribute heat through convection, and cooling effect of evaporation generally result in land heating up more quickly than water when exposed to the same amount of solar radiation.

Land surfaces absorb much more solar radiation than water. This is due to the fact that most land surfaces are darker than water which of course means more absorption of solar radiation and heat. Water reflects most solar radiation that reaches its surface back to the atmosphere.
