20．You probably don‘t think about soil often，but the following report may help you learn about science of soil．
What is soil made of？
Soil is made of sediments （沉积物） and humus（腐殖质）．Sediment is small pieces of rock broken down over time by rain，ice，and wind．Sediment is often found in water．Humus comes from decayed（腐烂的） plants and animals．It helps give plants a lot of the food they need to grow．
How does soil form？
Over centuries，rock breaks down into very small pieces．
The rock pieces mix with humus．
The humus gets thicker and thicker over time．Soil is formed（形成）l

Soils can be different colors and have different textures（质感）．Texture is how the surface of an object feels．Color and texture are two features（特征） of soil．
