Can any of you science guys explain this

Forget the quality of the photo. Why does the reflection off the water form a triangle which is larger at the horizon and gross to a point and then goes from a point back to a wider base at shore?

Maybe because the camera was bouncing up and down?

because the water, like the earth, is round?

I would guess a wave (gentle roller) where there is no reflection making the water higher and changing the angle to the sun... another possibility is a current at that point, but given the size of the body of water, doubt there's a current there unless there's a creek nearby.
That's as far as my science goes....anything else, ask Bill Nye, the science guy....

Ripples in the water where the reflection is missing. I'm guessing the triangle effect is due to less ripples going to more ripples where there is no reflection. Smoother water where the reflection is visible.

No, not tide, ripples on the surface. (wind)

I think that it's called the parallax effect.
The same way that light converges and then spreads out behind a lens. What appears as a dispersed image.
Is that what you were referring to?

Another possibility is a cloud that is shading the water where there is no reflection.

I think this is the closest answer. The earth is round and as you move farther away, the sun is hitting the area farther out a bit more direct causing it to appear brighter. And also, you are seeing water exposed to sun over a very long distance, but that distance appears compressed to the observer and you are much more aware of water up closer where the sun's angle is almost parallel to the surface.
From the perspective of perhaps 20' above the surface of the water, the horizon can be 20 miles away. You are really only perceiving the water out to a mile or so and beyond that, you have no real sense of distance.

Here is an article on glitter patterns.

I am assuming the glitter is enlarged because of increased ripples as you approach the near shore line.

You know, could be it's just the nature of optics with a point source reflecting on the water which takes different shapes.
But working about that stuff, why, I fear we are not seeing the forrest because of the trees.
That is a pretty darn nice shot! Really. It is interesting, unusual, and a good composition too. And the beads of light on the horizon are pretty cool too! (also a bit of lens flare going on there but that could be corrected in post).
So stop with the science lesson and start appreciating the uniqueness of that photo.
