The temperatures shown are approximate. A sample of crude oil may be separated in the laboratory by fractional distillation. The collection vessel is changed as the temperature rises to collect the different fractions. Crude oil comes in hydrocarbons of different size such as short-chain hydrocarbon molecules and long-chain hydrocarbon molecules.
Different molecules can be converted into different fuels such as petrol and refinery gas. Crude oil can also be divided into various temperatures from incredibly high temperatures to room temperatures. Also remember that hydrocarbon is a mixture of hydrogen and carbon!

Biosphere reserves - are protected environments that are recognized around the world for their conservation efforts and scientific skills. They help improve the environment and share information about conservation and the management of ecosystems. National Parks - are areas of special scenic, historical, or scientific importance set aside and maintained by a national government and in the United States by an act of Congress.
Wildlife Sanctuary - means a place of refuge for abused, neglected, unwanted, impounded, abandoned, orphaned, or displaced wildlife. The World Network of Biosphere Reserves is the collection of all biosphere reserves in countries as of May, Through appropriate zoning and management, the conservation of these ecosystems and their biodiversity is sought to be maintained.
The design of the reserve must include a legally protected core area, a buffer area where non-conservation activities are prohibited, and a transition zone where approved practices are permitted. This is done with regard for the sustainable use of natural resources for the benefit of local communities. This effort requires relevant research, monitoring, education and training. All the above are tools for implementing Agenda 21, the Convention on Biological Diversity and other international agreements.
