Because there's a whole lot of vacuum and zero gravity between the Earth and the sun.
Air is a fluid. Convection does not transfer heat from the sun to Earth because most of the intervening space is a vacuum.
a convection current transfers heat within a fluid.
A convection current, however, this can also occur with gases.
The transfer of heat by fluid is convection.
The convection of the water cycle is evaporation, condensation,precipitation,runoff

Air is a fluid. Convection does not transfer heat from the sun to Earth because most of the intervening space is a vacuum.
There is no air, or significant amount of any gas, in outer space.
Earth is like a giant magnet because of convection currents in the mantle. Convection is the transfer of hear by the motion of particles in a fluid.
Convection occurs when and where a fluid is in a gravity field and heat is applied to its base.
A convection cell is a system in which a fluid is warmed, loses density and is forced into a region of greater density. The cycle repeats and a pattern of motion forms. Convection cells in Earth's atmosphere are responsible for the blowing of wind, and can be found in a variety of other natural and manmade phenomena. Matter is constantly losing density in convection cells.
It is the convection on the liquid outer core/ and semi fluid mantle that is responsible for the movement of plates.
Convection happens due to the transfer of heat by the motion of a heated fluid such as air or water.

Convection currents are responsible for the movement of heat (and mass) within a fluid system. Heat wants to go from where it is to where it isn't. When atoms and or molecules of a fluid (a gas or liquid, for example) are hotter then their companion particles, they are less dense and rise in the fluid. Cooler, more dense groups of atoms or molecules take their place. Convection currents are thus set up, and heat travels "around" the system via those currents.
