Uneven heating of earth's surface
Actually, it's the uneven heating of the Earth's SURFACE that is the cause of most convection. Sunlight hits the ground. Depending on what sort of surface it is, more or less of the energy is absorbed, or the sunlight reflected. Snow and ice reflect more; light hitting at low angles of incidence are reflected. Sunlight hitting paved roads or plowed fields are mostly absorbed. The hot dirt and roads heats the air above them, causing the air to expand and rise; the cooler air above is more dense, and sinks.
The differing air temperatures cause the winds.

yes
Yes, that's the basic cause of convection.
The uneven heating results in some of the atmosphere to be warmer than other parts and changes in volume and pressure which result in updrafts and can cause thunderstorms and other violent weather.
yes
it causes the difference in density, denser water flows to the less dense parts
The primary effect of heating a gas is lowering the density of the gas, making it lighter. Uneven heating of gas creates local density gradients, which will drive bulk movement of the gas via natural convection to get rid of the local density gradients.
the uneven heating of earth's surface causes pressure differences which set air in motion
Surface currents are caused by wind, and affected by the rotation of the Earth and the gravity of the moon (tides). When the oceans are deep, convection within the layers can also affect the flow of currents. * While wind currents are greatly affected by uneven heating of the Earth's surface, there is no corresponding heating of the ocean bottom by the Sun. So currents do not form spontaneously at depth.
