Correct Answer: All are correct
Explanation:
Karst topography develops in regions underlain by limestone or other soluble rocks, leading to the formation of distinct landforms due to chemical weathering and erosion.
Stalactites:
- These are icicle-shaped formations hanging from the ceilings of caves, formed by the deposition of minerals from dripping water.
- Associated with karst topography.
Stalagmites:
- These are upward-growing formations on the floor of caves, formed by the deposition of minerals from water dripping from above.
- Associated with karst topography.
Uvalas:
- These are large depressions or basins formed by the merging of multiple sinkholes.
- Associated with karst topography.
Dolines:
- These are sinkholes or depressions formed when the roof of an underground cave collapses or due to the dissolution of surface limestone.
- Associated with karst topography.
Conclusion:
All four features (stalactites, stalagmites, uvalas, and dolines) are characteristic of karst topography.
Thus, the correct answer is All are correct.
