Answer:
The day/night temperature difference is much larger on land than the ocean because (c) the ocean has a larger heat capacity.
Explanation:
The ocean has a remarkable capacity to store heat. This is why its temperature is more stable than on land. Solar energy is gradually absorbed through the surface to the depth and that energy is moved around with their currents.
Ocean water can store huge amounts of solar energy, that is, from heat, which is released progressively. This property is what makes the ocean the great climate regulator and, therefore, two extreme types of climate can be recognized: the maritime and the continental.
The surface of the continents does not store large amounts of heat, and therefore, its thermal reserve is very scarce, so that the soil heats up very quickly during the day, but at night it cools in the same way. The heat has no time to penetrate the earth.
