Think about the three major types of soil: sand, silt, and clay. The diagram shows a comparison of these three particles, as well as a piece of gravel to show size differences. Which of these soils is best for supporting plant life and why?
A) Silt is best for most plants because roots are able to access air and water easily.
B) The large particle size of sand allows it to hold more water, making it best for plants.
C) Clay has the smallest particle size, allowing roots to grow further down than other soils.
D) Due to its small particle size, clay is sticky, and holds plants more securely than other soils.
