so it is a... right?
Yes. A. is right.
thank you
You're welcome.
The characteristic of karst topography is that it is associated with caves and caverns, so the correct option is:
a. caverns
To arrive at this answer, one can start by understanding what karst topography is. Karst refers to a landscape formed by the dissolution of soluble rocks, such as limestone, gypsum, or dolomite, over millions of years. This dissolution creates various landforms, such as sinkholes, underground drainage systems, and most notably, caves and caverns.
By eliminating the other options, we can determine that:
- Glaciers (option b) are not associated with karst topography. Glaciers form in colder regions and sculpt the landscape through the movement and erosion of ice, creating features like U-shaped valleys and moraines.
- Alluvial fans (option c) are cone-shaped deposits of sediment that are formed when the flow of water carrying sediments spreads out after leaving a narrow channel, such as a mountain valley. Alluvial fans are typically found in arid or semi-arid regions, but they are not a characteristic of karst topography.
- Dunes (option d) are hills or ridges of sand that are formed by wind or water action. Dunes are commonly associated with deserts and coastal regions. While sand may accumulate in karst areas, dunes are not typically a characteristic landform of karst topography.
Therefore, after assessing the options and considering the definition of karst topography, the correct answer is a. caverns.
