Basically, if we cut away the earth to look at the strata (the rock layers), they form an "S" shape (forwards or backwards). Use the link and check out a drawing. You'll have to scroll down to figure 101-7 to see it. The picture says it all.

They are or were called "fold mountains" but I've not seen the term used much now because it's taken as read. Essentially all mountains composed of sedimentary rocks above the continental basement (as I think you mean) are formed in this way, with the uplifting, folding and faulting being parts of the whole result. The cause is the Continental Collision part of Plate Tectonics.
the axial plane of a recumbent fold is horizontal and one limb is rotated more than 90 degree and called overturned limb.

A two-fold symmetry has a 360 degrees rotation. A three-fold rotational symmetry, on the other hand, has 120 degrees, and on a horizontal axis, a symmetry has 180 degrees.
Only the I has a horizontal line of symmetry. Visualize folding PIZZA in half through the letters. Only the I would fold down perfectly on top of itself, so it has a horizontal line of symmetry.
