Can this apparent brightness of Earth be attributed to the blue water all around? Whereas Moon is without water, and may be absorbing more light than it reflects?


The reflectiveness of a planet or moon is called its Albedo. If it reflected nothing, it would have an albedo of 0; if it reflected everything, it would have an albedo of 1. The Earth has an albedo of 0.37 whereas the full moon has an albedo of 0.12. So, the Earth reflects about 3 times as much of the light as the moon does. That is why it is brighter in the picture. Your guess that it is the water (but includes clouds as well as oceans) that are the main reflecting agents is correct; on the moon you only have the surface dust etc (called the regolith).
