Textures of Nature

As I look around my neighborhood, my mind is alerted to shapes, sizes and textures of nature. The diversity in nature is infinitive.
Light touches these textures and highlights curves, bumps, and smoothness of the surfaces. 
Age in nature is also infinitive. How old is a rock? Why do leaves drop off from their trees and begin to feed the soil? How do trees live hundreds of years?
Nature is full of unanswered questions. The best I can do in nature is to observe everything around me.
