The formation of Niagara Falls is mainly attributed to the geological background and glaciation. During glacial periods, rocks and sand carried by glaciers impinge on river beds, forming canyons and laying the foundations for waterfalls. The water speeds up, the erosion increases, and the waterfall moves forward. Climatic conditions and human activities also have an impact on the formation and change of waterfalls....
The Wenchuan Earthquake was caused by the collision between the Indian Plate and the Eurasian Plate and the stress accumulation in the Longmenshan fault zone. Before the earthquake, the area appeared earthquake precursor, the earthquake caused serious casualties and property losses, causing secondary disasters, Have a great impact on the lives of people in disaster areas....
The formation of Niagara Falls is the result of many factors. Geological background, glacial erosion, river cutting, geological structure changes and climatic factors all play an important role in its formation. Paleozoic submarine sedimentation, glacial erosion, The cutting of rivers, the uplift of the Earth's crust and the rainfall of the climate have all combined to shape today's spectacular Niagara Falls....
Jiuzhaigou Pearl Beach Waterfall is located in Aba Tibetan and Qiang Autonomous Prefecture, Sichuan Province. Its formation is mainly related to geological structure, water movement and geomorphologic evolution. Faults and folds of geological structure provide power, rich water movement and long-term geomorphologic evolution work together to form a unique waterfall landscape....
