Question

a. Clay, Silt, Sand, Gravel
b. Sand, Silt, Clay, Gravel
c. Gravel, Sand, Silt, Clay
d. Silt, Clay, Sand, Gravel

Answer 1

The correct order of the different mineral particle sizes in soil, from smallest to largest, is sand, silt, clay, gravel.

Step-by-step explanation:

The correct order of the different mineral particle sizes in soil, from smallest to largest, is b. Sand, Silt, Clay, Gravel.

In soil, sand particles are the largest, followed by silt, clay, and then gravel. Sand particles are between 0.1 to 2 mm in diameter, silt particles are between 0.002 and 0.1 mm, clay particles are less than 0.002 mm, and gravel particles are larger than 2 mm.

This order is important because it affects various soil properties, such as drainage, water retention, and nutrient availability, which can impact plant growth and agricultural practices.
