    Land: Lower specific heat capacity,

    heats up faster, cools down faster.

    Water: Higher specific heat capacity,

    heats up slower, cools down

    slower.

    Explanation:

    Specific heat capacity is the amount of heat energy required to raise the temperature of a substance per unit of mass.

    For simplicity, specific heat capacity of water is 4000 J/kg°C. It means you need 4000 Joules of energy to raise a kilogram of water by 1 degree Celsius.

    For simplicity, specific heat capacity of land is 1000 J/kg°C. It means you need 1000 Joules of energy to raise a kilogram of land by 1 degree Celsius.

    Now, let's add 4000 Joules of energy each to a kilogram of water and land.

    Water's temperature increases by 1 degree Celsius and land's temperature increases by 4 degree Celsius.

    From here you can see that for same amount of energy, water heats up slower and land heats up faster.

    Now, let's remove 4000 Joules of energy each from a kilogram of water and land.

    Water's temperature decreases by 1 degree Celsius and land's temperature decreases by 4 degree Celsius.

    From here you can see that for same amount of energy, water cools down slower and land cools down faster.
