It's impossible to name just *three* things found in soil as it's a complex mixture! Here's a breakdown of the major components:

1. Minerals: These come from broken-down rocks, providing essential nutrients like nitrogen, phosphorus, and potassium.

2. Organic Matter: This is decomposed plant and animal material, adding structure, water retention, and nutrients to the soil.

3. Air: Soil needs air for plant roots to breathe and for microorganisms to thrive.

4. Water: Water dissolves nutrients and makes them available to plants.

5. Living Organisms: Soil teems with life! This includes bacteria, fungi, insects, worms, and many others, all playing vital roles in soil health.

So, while you can't pick just three, these are the main components that make up the fascinating world of soil.
