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

1. What is the geomorphological process?Formed by differential erosion of varied rock strata, creating multi-step descents
2. What is the hydrological impact?Increases dissolved oxygen in water and creates humid microclimates supporting specialized flora
3. How does a cascading waterfall form?It forms when a river flows over layers of hard rock on top of softer rock. The softer rock erodes faster, making steps, and the water flows over them.
4. Why do cascading waterfalls have lots of plants and animals?The spray and mist keep the air moist and cool, which lets plants like mosses and ferns grow. The extra oxygen in the water also helps fish and other creatures.

Lithology: The physical characteristics of a rock, especially its composition and texture.
Riparian Vegetation: Plants that grow along the banks of rivers and streams.
Hydraulic Action: The erosive force of moving water, especially its ability to dislodge and transport material.
