Concept explainers
Small changes that result in the breaking up, crumbling, and destruction of any kind of rock are
a. decomposition.
b. weathering.
c. corrosion.
d. erosion.
The changes that take place as a result of breaking up, crumbling and destruction of any kind of a rock from the following options:
Decomposition.
Weathering.
Erosion.
Corrosion.
Answer to Problem 1AC
Solution:
Option (b) is correct.
Explanation of Solution
Introduction:
Rocks are the compounds made up of combination of minerals. It is a naturally occurring substance. Weathering denotes physical or chemical break down of rocks. It is of two types: Chemical and Mechanical.
Explanation:
Reason for the correct option:
Weathering is the process of breaking down of rocks in the presence of earth atmosphere.
Hence, option (b) is correct.
Reason for the incorrect options:
Option (a) is incorrect because decomposition refers to the state of decay of minerals into rocks. So, it is a wrong answer.
Option (c) is incorrect because corrosion is defined as the destruction of rocks by some chemical reactions. So, it is a wrong answer.
Option (d) is incorrect because erosion is the removal of top layers of rocks by the movement of winds. So, it is a wrong answer.
Hence, options (a), (c) and (d) are incorrect.
Conclusion:
Small changes which result in the breaking up, crumbling and destruction of any kind of rock are weathering.
