Do not copy the article. Write two things you learned, the way you would explain them to a friend.

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

1. What is the geological formation mechanisms?Primarily formed by fluvial erosion, differential rock resistance, and tectonic activity
2. What makes a waterfall special enough to be on the list of notable waterfalls?A waterfall usually needs to be at least 15 meters tall, or it must be important because of its history, culture, or how wide and powerful it is.
3. How do waterfalls form?When a river meets a harder rock layer, the softer rock below erodes faster, creating a steep drop. Tectonic uplift can also lift the riverbed, making the waterfall higher.

Fluvial Erosion: The process of land wearing away by the action of rivers and streams.
Differential Erosion: The process where softer rock erodes faster than harder rock, creating varied landforms.
Hydrophilic Vegetation: Plants that thrive in environments with abundant moisture, such as near waterfalls.
