Answer:
The shape of a mountain can provide clues to its age by revealing the processes that have affected it over time.
Mountains are formed through various geological processes, including volcanic activity, tectonic plate movement, and erosion. As mountains age, they can experience erosion from water, wind, and other natural forces, which can cause their shape to change over time.
For example, as a mountain ages, its peaks may become less sharp and more rounded due to erosion. This is because the softer rock that makes up the mountain is eroded more quickly than the harder rock, causing the peak to become more rounded. In addition, the height of the mountain may decrease over time as it erodes.
The presence of certain geological features on a mountain can also provide clues to its age. For example, if a mountain has layers of sedimentary rock, these layers can be dated using radiometric dating techniques to determine the age of the mountain.
Overall, the shape of a mountain can tell its age by revealing the geological processes that have affected it over time, such as erosion and the presence of certain geological features.
