The rock particles that make up soil come from parent bedrock. Weathering breaks bedrock into smaller and smaller pieces. The characteristics of any soil depend mostly on the type of parent bedrock. Just like you have characteristics that are like your parents, soils have characteristics that are like those of the parent bedrock. Take a look at the soil textural triangle. Soil particles are classified by size; sand particles are the largest and clay particles are the smallest. Most soils are some mixture of these three particles.
Imagine that a soil is 85% composed of weathered sandstone. Over time, a river flowing over the bedrock deposits sand and a very small amount of clay. By using the soil textural triangle, scientists have decided that the soil is mostly likely

A) silt loam.
B) clay loam.
C) loamy sand.
D) sandy silt loam.
