The radiation form the Sun causes water to evaporate form the surface of the sea. This evaporated water is carried in the air until the air is cooled and if the cooling happens over land (say because it has to go higher to get over a mountain range) the water condenses out of the air as clouds and rain. The rain collects in rivers and flows down hill to the sea.
No, gravity does not directly cause rivers to flow. Rivers flow due to the force of gravity pulling the water downstream. The elevation gradient along the river channel allows the water to move from higher to lower elevations, creating the flow of the river.
