A large belt of grey and brown Vertosols also run from the New South Wales border to Charters Towers—corresponding with Brigalow forests. This soil type is usually associated with previous volcanic activity and is mainly located along the Great Dividing Range. Large areas of these soils occur around Kingaroy and Atherton where they are used for intensive crop production. Dermosols are red, brown, yellow, grey or black and have loam to clay textures.
Soils are complex mixtures of minerals, water, air, organic matter, and countless organisms that are the decaying remains of once-living things. So then, what is dirt? Dirt is what gets on our clothes or under our fingernails. It is soil that is out of place in our world — whether tracked inside by shoes or on our clothes. There are seven general roles that soils play:. Soil Profile There are different types of soil, each with its own set of characteristics. Put the horizons together, and they form a soil profile.
Clay is a type of fine-grained natural soil material containing clay minerals. Clay is the oldest known ceramic material. Prehistoric humans discovered the useful properties of clay and used it for making pottery. Between one-half and two-thirds of the world's population still live or work in buildings made with clay, often baked into brick, as an essential part of its load-bearing structure. Clay is a very common substance. Shale , formed largely from clay, is the most common sedimentary rock.
Soil can be categorised into sand, clay, silt, peat, chalk and loam types of soil based on the dominating size of the particles within a soil. Sandy Soil is light, warm, dry and tend to be acidic and low in nutrients. Sandy soils are often known as light soils due to their high proportion of sand and little clay clay weighs more than sand. These soils have quick water drainage and are easy to work with. They are quicker to warm up in spring than clay soils but tend to dry out in summer and suffer from low nutrients that are washed away by rain.

In the U. One of the most dangerous types of construction work is trenching, which kills 40 construction workers every year. Workers can suffer death or serious injury within minutes of being caught in a trench cave-in. But these deaths can be prevented. The video you are about to see shows one of the steps, classifying soil, that employers must follow so that trenching work can be done safely.
