Read the following case and answer the questions:
 
During the rainy season, Arun visited his grandparents' village. He noticed that some large rocks on the hillside had broken into smaller pieces, while a few rocks had developed a reddish outer layer after remaining exposed to rain for many years. Near the foot of the hill, he observed that flowing rainwater had carried small rock particles and deposited them along the riverbank. His grandfather explained that these changes occur naturally over a long period and help in the formation of soil. Arun became curious to understand the different natural processes responsible for these observations.
 
1. Identify the two different types of weathering observed by Arun. Explain how each observation represents a different type of change.
 
Arun observed when the rocks . This is a because .
He also observed when some rocks developed a . This is a because when rocks containing iron react with water or moist air.
 
2. Arun noticed that the broken rock particles were carried away by flowing rainwater and later deposited along the riverbank. Name the process responsible for this observation and explain how it occurs.
 
Name the process responsible for this observation and explain how it occurs.
The process is called .
During erosion, . When the , these particles along riverbanks, lakes, or other places.
 
3. Based on Arun's observations, explain how weathering and erosion are related but different processes.
Weathering is the process in which  due to natural factors.
Erosion is the process in which these by wind or flowing water.
Thus,
