How many layers do sedimentary rocks have?
One layer is deposited first, and another layer is deposited on top of it. So each layer is younger than the layer beneath it. When the sediments harden, the layers are preserved. Sedimentary rocks formed by the crystallization of chemical precipitates are called chemical sedimentary rocks.

Iron, manganese, and calcium carbonate from limestone all common minerals that can cause water to range in color from red and orange to green and blue.
Why do river rocks turn white?
“Calcium deposits. In the summer, when various algae forms grow vigorously in the warm and sunny waters, the calcium is picked up and put into plant tissue. As the water has dropped, more rock surface is exposed, and more calcium deposits are exposed, and they make the rocks appear white.
