Weathering profile of Volcanic Tuff

This lecture briefly discuss on Weathering profile of Volcanic Tuff. Weathering profile of volcanic tuff in a road cut after fifteen years of experience of weathering processes. Physical or mechanical weathering includes weathering processes that cause rock or sediment to break down into smaller pieces without having changing the chemistry on the rock. Water trapped in micro-cracks inside of rock can expand while in freezing cycles and exert tremendous stresses for the crack wall and lead to rock to break separate. Finally discuss on Soil Forming Factors, they are: Climate, Organisms, Relief, Parent material and Time.
