Final answer:
The statement that sand and loose soil are loose impediments only on the putting green is false; they can be removed anywhere on the golf course. Soil compaction changes soil composition, and the topsoil (A horizon) and subsoil (B horizon) are different layers of the soil profile.
Step-by-step explanation:
The statement that sand and loose soil are considered loose impediments on the putting green but not elsewhere is False. According to the Rules of Golf, loose impediments can be removed anywhere on the course, including on the putting green and in bunkers. The term loose impediments refers to natural objects such as stones, leaves, and twigs, and also includes sand and loose soil.
Soil compaction can result from heavy machinery or foot traffic and can significantly change soil composition by making it denser, reducing aeration and water infiltration. Within a soil profile, a vertical section of a soil, the topsoil is also known as the A horizon, which is the layer where organic material mixes with mineral particles. The B horizon or subsoil lies beneath the topsoil and generally contains less organic material with more compacted soil particles. Silt soil particles, which fall between 0.002 and 0.1 mm in diameter, are an important component of soil as they affect the soil's ability to retain moisture and nutrients.
