Gradients: Fold Mountains

Fold mountains originate as ocean mounds and form through tectonic plate movements, creating steep gradients. Gradients are calculated by dividing vertical height by horizontal distance. Initially, the ocean bed is flat, but over time, slight gradients develop, leading to mountain growth above sea level. Climbers face challenges with varying gradients, including undefined ones on sheer cliffs. As the Earth moves, these mountains continue to grow, making gradient calculations uncertain.

What challenges do climbers face when scaling a mountain with a gradient of 0.4?

Discuss the concept of undefined or infinite gradients in relation to sheer cliff faces.
