What is one reason for high sediment in Himalayan rivers?
Answer and explanation
Correct answer: Intense erosion on the steep Himalayan slopes
The Himalayas are young fold mountains with steep slopes and relatively unstable rocks. Fast-flowing rivers erode these slopes intensely and carry soil, sand, and gravel, so their sediment load is high. Mixing of seawater at a river mouth does not cause sediment to be produced. Exam tip: link steep gradient and fast flow with greater erosion and sediment load.
