Explanation / Answer

1. 2% 2. true 3. Clay rich clay has incredibly small particles. This means that clay has little space between individual particles, allowing for virtually no drainage. For this reason, clay soil is bad for growing things in, because water tends to not be able to escape, and it is difficult for root systems to break through the clay layer. Clay soils tend to be much older than sandy soils, since it makes many, many years for rock particles to break down to be small enough to form clay.
