So 50% of the sun's radiation is lost before it reaches earth's surface.
See the diagram link below.
55% is absorbed by the atmosphere.
The visible outside part of the Sun can be said to be its surface. But the Sun doesn't have a solid surface on which you might stand, if that's what you mean. The "surface" we see is called the "photosphere".
If you think it has a scratch get a towl ,NOT A KLEENEX, and get it a litle wet. Dont get it drinched just anough that it will wash away the dust and other debris If it has a scratch sit it on a flat suface and hold it down by puting you finger as close to the inside edge ,where the hole is, as possible. and scrub with a dry cloth over and over again.

I have 4 cats and they are always scratching my disk.

Suface currents form from the wind. The wind can make the surface cold or warm.
Due to suface tension the suface of two moist grain act a suface attraction force upon each other and attracted to wards each other.

YOu
The suface are of a rectangular prism is the area of each face added together for a total.
The suface area of a sphere with a radius of 7 meters is 615.75m2
