It will be a point if the plane is tangent to the sphere.
The intersection of a sphere with a plane is a point, or a circle.
6 maximum points of intersection
It is a circle - or at its extreme, a point.
In spherical geometry we look at the globe as the sphere S^2. Any plane intersecting the sphere will create a great circle. Now if you take any point on the globe and reflect it across that plane, you have another point that is equidistant from the plane. The sets of all these points will be equidistant from the great circle.
Technically you can not trace a sphere. If the base conditions are the same as for the other solid shapes, for example a cylinder, there is a base on which the cylinder rests, which creates the circle when it is traced. A sphere on a base would be touching in one point, which would be a dot. If you trace half a sphere, yes, than you do get a circle.
The intersection of a sphere with a plane is a point, or a circle.

We're having a hard time making out the dark grey area from here. But the intersection of a plane and a sphere is always a circle.
A circle~
A Circle.
A circle, which could degenerate to a point.
The great circle is the intersection of a sphere and any plane passing through its centre. Given two distinct points on the surface of a sphere, those two points and the centre of the sphere define a plane. [If one of the points is at the antipodes of the other, an infinite number of planes are defined.] The great circle is the circle formed when that plane meets the surface of the sphere.
The dark area is so dark that I'm unable to see it from here. But I do know that in general, the intersection of a plane and a sphere is a circle.
Not necessarily. A plane dissecting a sphere would create a circle in that plane. so in order for the "line" to be both on the plane and the sphere the line would have to be a curve or segment of a circle.
The great circle is simply the intersection of a sphere with a plane through its centre. It is, therefore, equivalent to the circumference.Then r = C/(2*pi) = 112.4 units.
The sphere forms a circle in the plane. There are two bits of sphere which are spherical caps with a circular base.
a circle!
