Question

Which of the following are arranged in order of INCREASING (smallest to largest) particle size?

A. silt --> clay --> sand
B. clay --> silt --> sand
C. sand --> clay --> silt

Answer 1

The arrangement of materials in order of increasing particle size from smallest to largest is clay, silt, sand, which corresponds to option B.

Step-by-step explanation:

A student has asked about the arrangement of materials in order of increasing particle size. In the context of sedimentary particles, clay has the smallest particles, followed by silt, and then sand has the largest particles of the three. Therefore, the correct order from smallest to largest in terms of particle size would be:

• Clay
• Silt
• Sand

This corresponds to option B, which is clay --> silt --> sand.
