Coal and Petroleum is scoring chapter, and students can practice by solving ICSE Model Paper Class 8 Chemistry provided by the Extramarks app. By learning ICSE Model Paper Class 8 Chemistry students will know that there are so many materials which cater daily to our different needs. You are drinking water, eating food, breathing air, going to school etc. All these things are available to you, but are they all cost-free and readily accessible, without fear of one day being depleted? No. it isn't all readily available to you. Sunlight, air, etc., for example, are resources that you find in abundance and will not be depleted any time soon. Such resources are therefore called Inexhaustible Natural Resources. Certain resources are being produced in very limited quantities, and it will take a very long time to replenish those resources. These resources are classified as exhaustive natural resources. Ex: coal, iron, petroleum, natural gas etc. and for more examples, students can take online classes for ICSE Model Paper Class 8 Chemistry from the Extramarks app. Coal and Petroleum are produced as a consequence of the destruction of the old plant life that existed millions of years ago. This dead plant matter started piling up and eventually developed a substance called peat. Over time these materials were converted into coal by heat and pressure from geological processes because these are primarily made from fossils, they are also known as fossil fuels. Coal formation dates back to millions of years ago, when only massive dense forests covered the earth, with huge trees, shrubs, ferns etc. and for full information, students can learn ICSE Chemistry Sample Paper for Class 8 from the Extramarks app. These plants underwent their life cycle and eventually fell back to the ground withering away, most of them being swamps. New plants replaced these, these underwent a life cycle, and the entire process repeatedly occurred over the years as a result of which the earth bed started to collect all those dead plants. For more information on Coal and Petroleum, students can try to solve the ICSE Chemistry Sample Paper for Class 8 provided by the Extramarks app. Chemistry is one of the very few subjects that require comprehension and memory skills as theoretical and numerical questions go hand in hand in physics. The ICSE Chemistry Sample Paper for Class 8 stick to the ICSE Class 8 Chemistry Syllabus and aim to provide the students with an atmosphere just like the one they get when presented with the actual paper of the exam.
