Explanation:
Statement 1: Lichen and plant roots break the rocks into pieces.
This statement is true. Lichen is a combination of algae and fungi that grow on rocks. The fungi in lichen produce acids that slowly break down the rocks into smaller pieces. Plant roots, especially those of larger plants, can also break rocks as they grow and expand. This process is known as physical weathering.
Statement 2: Topsoil is the layer of hard rocks.
This statement is false. Topsoil is not the layer of hard rocks. Topsoil is the uppermost layer of soil, typically a few inches to several inches thick, that contains a high concentration of organic matter. It is rich in nutrients and is where most plants grow. Below the topsoil, there are layers of subsoil and bedrock.
Conclusion:
From the above analysis, we can conclude that statement 1 is true and statement 2 is false. Therefore, the correct answer is option 'A' - Statements 1 is true and 2 is false.
