To the extent that the Sun has a "surface", that surface is made of plasma, a super-hot very energetic state of matter that's beyond vaporous. Any solid object that came anywhere near the Sun would be boiled into its constituent elements and the matter would likely be disassociated with its electrons.
The corona
Sun spots (magnetic storms).
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".
The sun does not have a suface because it is a star, and stars are made of gas
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.

suface
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
