Soil is formed from the weathering of rocks and minerals. The surface rocks break down into smaller pieces through a process of weathering and is then mixed with moss and organic matter. Over time this creates a thin layer of soil. Plants help the development of the soil.
In NSW it is a different story. It provides guidelines to parents and says a child aged 10-12 years can be left for up to 12 hours but not between 10pm and 6am. They must have a back-up adult available and can look after one or two other smaller children.
In addition, children under age 4 or less than 40 pounds (15 kg) must be in a child car seat, usually available from your car hire company. Driving in Florida while drinking alcohol or while under the influence of alcohol is illegal.
