![Check Mark](/static/check-mark.png)
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.
