Consider the following statements. 1. In areas of tilted strata, wher...
Statement 1: In areas of tilted strata, where permeable and impermeable rocks alternate, the water emerges at the base of the permeable layers.
Explanation:
- Tilted strata refer to rock layers that are not horizontally aligned but have an inclination or tilt.
- Permeable rocks are those that allow the movement of water through them, while impermeable rocks do not allow water to pass through easily.
- In areas where permeable and impermeable rocks alternate, the water tends to accumulate and flow along the boundary between these layers.
- The water seeps through the permeable rock layers until it reaches the base of these layers, where it may emerge as springs or seepages.
- This occurs because the impermeable layers below prevent water from further downward movement, causing it to accumulate and find an outlet at the base of the permeable layers.
- Therefore, statement 1 is correct.
Statement 2: In well-jointed rocks, water may percolate downwards until it reaches a joint which emerges at the surface.
Explanation:
- Well-jointed rocks have cracks or fractures, known as joints, that provide pathways for water to percolate through.
- When water enters these joints, it can travel vertically downward, following the path of least resistance.
- Eventually, the water may reach a joint that reaches the surface, allowing the water to emerge as a spring or seepage.
- This phenomenon occurs because the joint provides a direct pathway for the water to escape to the surface.
- Therefore, statement 2 is also correct.
Conclusion:
- Both statement 1 and statement 2 are correct.
- In areas of tilted strata, water emerges at the base of permeable layers due to the presence of impermeable layers below.
- In well-jointed rocks, water percolates downwards until it reaches a joint that emerges at the surface, providing an outlet for the water.
- Hence, option C, which states that both statements are correct, is the correct answer.
