What does it mean if the seasons change, the leaves fall to the ground and the ground is covered with silver?

If the seasons change and the leaves fall to the ground in silver, it means that all the leaves fall to the ground in autumn. A vast expanse of whiteness describes that many leaves fall to the ground with a thick layer, especially some broad-leaved trees. In autumn, these broad-leaved trees will lose their leaves, and the leaves will slowly fall to the ground, forming a thick layer, like a carpet, which will be very comfortable for people to step on and the scenery will be beautiful.
