Question

Amy made the table shown to describe two processes.

Amy's Table
Process A Process B
A rock crumbles easily when oxygen reacts with some substances present in the rock Plants grow through the cracks in rocks and break the rocks apart

Which statement is true about the processes described in the table?
Both Process A and Process B represent physical weathering.
Both Process A and Process B represent chemical weathering.
Process A is physical weathering and Process B is chemical weathering.
Process A is chemical weathering and Process B is physical weathering.

Answer 1

The correct statement is that Process A is physical weathering and Process B is chemical weathering.  

Mechanical weathering also known as physical weathering and disaggregation, which makes big rocks to crumble into little ones. The plants can work as an agent of physical weathering. The plant seed may sprout in the soil, which has got collected in a cracked rock. With the growth of the root, the cracks get widen, ultimately dissociating the rock into pieces. With time, the trees can dissociate even larger rocks.  

On the other hand, chemical weathering refers to the disintegration or erosion of rocks, building substances, and other substances with the help of chemical reactions, like crumbling of rocks, when oxygen reacts with certain components present in the rock.
