In moderate and cold climates, a tree gains one ring every year, which allows us to estimate its age. Where else we can estimate age in similar fashion?
on the beach, layers of sand and grit
at the bottom of the lake, sedimentation
in the craters, pyroclastic rocks
in the glaciers, layers of clay and sand
At the bottom of some lakes the sediments stay very well preserved. Lamina lucida and lamina densa are created during the one year cycle. This fact can be used as lake's age estimation.
