Across
- 2. care of Earth’s resources, like soil and water. It means using them wisely.
- 3. fast water can move through soil. Sandy soil has high permeability because water passes quickly.
- 4. small pieces of soil to test what it’s made of. For example, farmers use it to check if the soil is healthy for planting.
- 5. water moves down through soil. Think of how coffee filters water.
- 8. polluted soil so it can be used again. It helps make land healthy.
- 10. much salt is in the soil. Too much salt can harm plants.
- 11. measure of how acidic or basic soil is. Some plants grow better in certain pH levels.
- 12. water washes away nutrients from soil. This can leave plants without food to grow.
- 13. water enters the soil. It’s like when rain sinks into the ground instead of forming puddles.
Down
- 1. natural resources in a way that doesn’t run out. It helps future generations.
- 6. many tiny spaces or holes are in soil. More holes = more air and water can pass.
- 7. much water soil can hold. If soil holds too little, plants dry out.
- 9. soil gets packed too tightly. Heavy machines or too much walking on soil can cause this.
