1. Oxygen (O): This is the most abundant element in the Earth's crust and is a key component of many minerals found in rocks and soil.
2. Silicon (Si): Another highly abundant element, silicon is the foundation for silicate minerals, which make up a significant portion of rocks and soil.
3. Aluminum (Al): Aluminum is a common element in rocks and soil, often found in combination with silicon and oxygen to form various minerals.
These three elements are just a starting point, and many other elements can be found in soil and rocks depending on their specific composition and origin.
