The importance of soil quiz for Grade 5 science.

📚 Quick Study Guide

• 🌍 Soil is the loose upper layer of the Earth's surface where plants grow.
• 🌱 It's made up of minerals, organic matter (like dead leaves and bugs!), water, and air.
• 🌧️ Weathering (wind, rain, and temperature changes) breaks down rocks into smaller pieces to form soil.
• 🐛 Decomposers (like worms and bacteria) break down dead plants and animals, adding nutrients to the soil.
• 🌾 Soil provides plants with support, water, and nutrients.
• 🐾 Different types of soil exist, including sandy soil, clay soil, and loam soil.
• 💧 Sandy soil drains water quickly, while clay soil holds water well. Loam is a mix of both and is best for most plants.
