Oak Trees Research Paper

Oak trees have a very long and diverse history. Oak wood is very unique and valuable. Wood has been around for about four hundred million years. The oak tree is a part of the Fagceae family, the Quercus kingdom, the Fagales order, and the Plantae kingdom. There are approximately six hundred different species of oak trees. Northern Oak, White Oak, Black Oak, and Chestnut Oak are just a few examples of the many different species of oak trees. Some oak trees only grow to be shrubs. Others grow to be over a hundred feet tall. The tallest oak tree in the world is one hundred and forty-three feet tall. Oak trees life spans tend to range from two hundred years to four hundred years, but there are always exceptions such as the Jurupa tree. The Jurupa

Fires are very dangerous. Fire is not matter, and it is matter in the process of transformation. Fire needs oxygen, heat, and fuel present at one time to form. A fire starts when a fuel such as wood heats to a high temperature. It is usually caused by focused light or friction. When the fuel gets to be about three hundred degrees Fahrenheit, the heat starts decomposing materials and turns them into smoke. The fire will continue to burn and get hotter. Eventually, the fire decomposes too many materials that the fuel can no longer support fire. The fire will begin to die down. When the fire is completely gone, the wood appears black. This is called ash. Ashes are the remaining materials of wood after a fire. Fire has many different classes. The difference between each class is what the fire is burning. Class A is when fire burns wood, paper, cloth, trash, and plastic. These materials can be put out very easily if you catch them burning quickly. Class B includes liquids such as: oil, paint, gasoline, and propane. These materials are very dangerous to burn. If gasoline is on fire, it can possibly cause an explosion. Class C is when fire burns electrical equipment such as house-hold appliances. For example, a Class C fire would be if your oven or microwave began a fire. Class D fires are when combustible metals such as aluminum start a fire. Class K fires are when cooking oils and grease catch on fire. All of the materials listed above are highly flammable and can cause a fire in your home. All of these fires can be prevented by taking simple precautions. First, when you are cooking food never leave the area. Next, never put flammable materials over a stove when cooking. There should always be a fire extinguisher handy. Always remember to never let grease pile up by the stove, and never let a child go by a fire without an adult present. When a fire does occur in
