What is the difference between block disintegration and exfoliation
Answers
Answer:
block disintegration :
where difference between day and night temperature is large ,rock expand and contract .they expand during the day, when temperature is high and contract during night when temperature is extremely low .this result in splitting of rock .example in the desert .
exfoliation :
the changes in temperature may create fissures or crack in rocks. water then enter into crack and outer layer of rock peels off.
Answer:
Block disintegration and exfoliation are the process of physical weathering
Explanation:
Block disintegration is caused by the heat and frost action, arid regions experienced high variation of day and night temperature which causes cracks in the rocks due to freeze and thaw action. Exfoliation is otherwise known as onion weathering which means peeling the rocks due to the combined action of heat and wind. Due to difference between high and low temperature, formed rock sheets are detached due to the presence of strong winds.
