Times to be arranged. Lake origin Lakes are created by geologic forces.
Lakes eventually become extinct because of erosion and sedimentation.

Alkalinity-pH relationships, inorganic carbon. Alkalinity and inorganic carbon relationships in natural waters. Light Water transparency, spectral properties of light absorption, color of lakes. Heat Annual patterns of heat gain and loss, temperature stratification.
