Question

As per the Unified Soil Classification System (USCS), the type of soil represented by '**MH**' is

Correct answer (A) Inorganic silts of high plasticity with liquid limit more than 50% Solution In the Unified Soil Classification System (USCS), soil symbols consist of two letters: 1. The first letter indicates the primary soil type: M stands for Silt (from the Swedish word Mo). 2. The second letter indicates the plasticity or grading: H stands for High plasticity (Liquid Limit > 50%). Therefore, MH represents inorganic silts of high plasticity with a liquid limit greater than 50%. Turn this into a strength. Explore AI-powered practice and doubt support with Success Tracker.
