Final answer:
Mixed layers, more precipitation, and cooler temperatures all increase the rate of soil formation.
Step-by-step explanation:
The rate of soil formation is influenced by several factors. One factor is the presence of mixed layers or horizons in the soil profile. These mixed layers contain a variety of minerals and organic matter which contribute to the formation of soil.
Another factor that increases the rate of soil formation is more precipitation. Rainfall helps to weather rocks and minerals, breaking them down into smaller particles that become part of the soil.
Cooler temperatures also promote soil formation. Cold temperatures slow down the processes that break down rocks and minerals, allowing more time for them to weather and contribute to soil development.
