章節(jié)摘錄

　　Soil is made up of a number of layers （層）, each having its own distinctive color andtexture. The upper layer is known as the litter. It acts like a blanket, limiting temperaturechanges and reducing water loss. The topsoil layer is made up of small particles of rock mixedwith rotten plant and animal matter called humus （腐殖質(zhì)）, which is black and gives the topsoilits dark color. This layer is usually rich in nutrients, oxygen, and water. Below the topsoil is thesubsoil, a layer that contains more stones mixed with only small amounts of organic matter. Thislayer is lighter in color because of the lack of humus. Beneath the soil lies a layer of bedrock.　　Soil forms from the bottom up. Over time bedrock is attacked by rain, wind, frost, andsnow. It is gradually broken down into smaller particles in a process called weathering. Plantsbegin to grow, and rotten materia　　s enrich the topsoil. Most of the soil in Eastern Canada, forexample, was formed from weathered rock that was exposed when the ice disappeared 12,000years ago.Water Beneath the Soil.　　Surface water collects and flows above the ground in lakes, ponds, and rivers. Once in thesoil or rock, it is called groundwater. Gravity pulls groundwater through the soil in a processcalled percolation （滲透）. Eventually the water reaches a layer called the water table. Under thisis bedrock through which water cannot percolate.　　As water percolates downward, it dissolves organic matter and mineras from the soiland carries them to deeper layers. This causes a serious problem because plants require thesenutrients for growth. 　　……
