The best answer among the options provided is:
A: "Both ridges and mountains rise up to high elevation; however, a mountain is a singular peak whereas a ridge is a long chain of continuous elevation for some distance."
Comparison:
- Elevation: Both features are associated with high elevations.
- Structure: A mountain typically refers to a single notable high peak, while a ridge is characterized as a series of connected peaks or elevated areas.
Contrast:
- Form: A mountain is singular and distinct, while a ridge is an elongated feature that spans a significant distance.
The other options (B, C, and D) contain inaccuracies regarding the definitions of ridges and mountains and do not appropriately represent the physical characteristics of these geological formations.
