Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the primary formation process?Differential erosion, where a resistant caprock protects underlying softer strata
2. What is the geological significance?Provide insights into past geological eras and environmental conditions
3. How do mesas form?Mesas form when a hard caprock of sandstone, basalt, or limestone covers softer rock underneath. Water and wind erode the softer layers, leaving the hard caprock on top.
4. Why do mesas have flat tops?The hard caprock protects the top from erosion, so the top stays flat while the sides wear away into valleys and canyons. This creates the classic flat‑topped shape.

Geomorphology: The scientific study of landforms, their origin, and evolution.
Xeric Environment: An ecosystem characterized by a severe lack of available water.
Stratigraphy: The study of rock layers (strata) and layering (stratification) in rock formations.
Fluvial Processes: The actions of rivers and streams in shaping the landscape.
