(1) Gravitational force.
(2) A and B ; 'D' also indirectly affects the pressure.In coastal stations, a temperature gradient is produced between the land area and the adjoining sea area as absorption of solar radiation by land and sea differs.Due to this temperature gradient, a pressure gradient is produced resulting in sea-breeze.
(3) False.
