Which of the following is NOT typically associated with limestone caves?

Limestone caves, as a geological formation, are primarily associated with specific characteristics that emerge from the erosion and dissolution of limestone by acidic water. Typically, cave pools are formed as water collects in depressions or low spots within the cave system, creating distinct aquatic environments. Cave ecosystems, which include various species of plants and animals adapted to the unique conditions of caves, are also commonly found in limestone caves due to their moisture and nutrient sources.

Vaulted ceilings, which can be seen in many limestone caves, are a result of the dissolution processes that create large chambers and open spaces within the cave structure.

In contrast, desert landscapes do not have a direct connection to the formation or characteristics of limestone caves. Deserts are characterized by arid conditions and lack the necessary water flow that contributes to the development of limestone caves. Thus, the presence of desert landscapes is the choice that does not align with the typical features associated with limestone caves.
