Question

which of the following are arranged in order of increasing (smallest to largest) particle size? clay → silt → sand silt → clay → sand sand → clay → silt

Explanation:

To determine the correct order of increasing particle size, we recall the particle size ranges of clay, silt, and sand. Clay particles are the smallest (typically less than 0.002 mm), silt particles are larger than clay (0.002 - 0.05 mm), and sand particles are the largest (0.05 - 2 mm). So the order from smallest to largest is clay → silt → sand.

Answer:

A. clay → silt → sand
