examples of soil types Grade 3

📚 Quick Study Guide

• 🌍 Soil is Important: Soil is the loose top layer of the Earth's surface where plants grow. It's made up of tiny pieces of rock, minerals, and organic matter (stuff from dead plants and animals).
• 🧱 Clay Soil: Clay soil feels sticky when wet and is made of very small particles that pack tightly together. It holds water well, but it can be hard for plant roots to grow through.
• 🏜️ Sandy Soil: Sandy soil feels gritty and loose. It's made of larger particles that don't hold water very well, so water drains quickly.
• 🌱 Loamy Soil: Loamy soil is the best for growing most plants! It's a mixture of sand, clay, and silt (another type of soil particle) along with humus (decomposed organic matter). It holds water well but also drains well, and it's full of nutrients.
• 🪨 Silty Soil: Silty soil feels smooth and silky when wet. It holds more water than sandy soil but not as much as clay soil.
• 🐛 Humus: Humus is the dark, organic matter in the soil that comes from decomposed plants and animals. It's super important because it provides nutrients for plants and helps the soil hold water.
