How does weather affect conditions inside Niagara Cave?

The correct answer focuses on the stability of the cave environment, which is a key characteristic of many limestone caves, including Niagara Cave. Caves like Niagara typically maintain a consistent internal temperature and humidity level, regardless of the external weather conditions. This phenomenon occurs because the thick rock layers surrounding the cave insulate it, preventing outside weather variations from significantly influencing the internal climate.

While the weather may affect the surface conditions outside, such as temperature fluctuations or rain, the cave itself remains largely unaffected. This stability allows for the preservation of unique geological features and ecosystems within the cave, making it an interesting destination for visitors.

Other options suggest changes to the internal conditions, such as dampness or flooding, which can occur in some cave systems during significant rainfall but do not apply to Niagara Cave’s consistently stable environment.
