Why is this the answer?

The answer is snow because this wonderful riddle paints a beautiful picture of what snow is like and what happens to it during the changing seasons. Let us look at each special clue to see how it fits the answer. First, the riddle says, "High born, my touch is gentle." Snow is called "high born" because it is created way up in the cold clouds, very high above the ground. When it falls, the tiny snowflakes land so softly on everything. They are very gentle and light when they touch your coat or your face, which is a perfect description of snow. Next, the riddle says, "Purest white is my lace." A fresh layer of snow makes the whole world look bright and clean, the purest white color you can imagine. If you look very closely at real snowflakes with a magnifying glass, you can see that they have six beautiful, delicate arms that look like fine patterns on a special fabric called lace. This clue definitely points to snow. The third clue is about sound: "Silence is my kingdom." When a big, fluffy snowstorm covers everything, it makes the outside world get very quiet. The soft snow acts like a giant sound blanket that absorbs noise, making the neighborhood calm and muffled. When snow is everywhere, it truly feels like a peaceful, quiet kingdom. The last part of the riddle is the smartest of all: "Green is the color of my death." Snow is frozen water, and it needs cold weather to stay on the ground. When the warm spring sunshine arrives, the snow melts away and disappears, which the riddle calls its "death." The color that comes back when the snow is gone is the bright green of the grass, leaves, and all the growing plants. The riddle describes the natural process of snow melting in spring when the world turns green again.
