    It depends upon the emissivity of the surface.

    if you are not aware what emissivity is defined as the ratio of the energy radiated from a material's surface to that radiated from a blackbody (a perfect emitter) at the same temperature and wavelength and under the same viewing conditions. it is a dimensionless number between 0 (for a perfect reflector) and 1 (for a perfect emitter).
    (ref: )

    it is the measure of how an object radiates heat.

    the higher the emissivity “ε” the higher the temperature it emits. the perfect emitter of heat is called a “black body.”
    a black body has an emissivity ε measure of 1.


    for the emissivity of

    water: 0.95~0.963
    sand: 0.76

    therefore, water would emit more heat than of the sand.

    Body waves helped them because body waves can travel through the earth's inner layer. the p-wave or the primary waves can travel solids, liquids and gases. s-waves or the secondary waves cannot travel through any liquid medium, so the seismologists concluded that the outer core is liquid.
