1.	Which of the following type of soil has the smallest particle size?1. Sand2. Silt3. Clay4. Fine sand
Answer» Correct Answer - Option 3 : Clay The correct answer is Clay. The particles that makeup soil are categorized into three groups by size – sand, silt, and clay. Single clay particles cannot be seen with a naked eye. Size is less than 0.002 mm in diameter. Sand particles are the largest and clay particles the smallest. The particles in clay are tightly packed together with each other with very little or no airspace. This clay has very good water storage qualities and makes it hard for moisture and air to penetrate into it. It is very sticky to the touch when wet, but smooth when dried. It is the densest and heaviest type of soil that does not drain well or provide space for plant roots to flourish.
