Magnitude simply means “how much”. In physics, we use many kinds of numbers, two of which are scalars and vectors. A scalar is a number that only has a magnitude or an amount. Magnitude is the quantitative value of seismic energy. It is a specific value having no relation with distance and direction of the epicentre. We can say that magnitude is the size of an earthquake. It is a logarithmic scale in which magnitude increases 10 times with each increase in number. For example: 6 bananas.

Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives off heat. During combustion, new chemical substances are created from the fuel and the oxidizer. These substances are called exhaust. Most of the exhaust comes from chemical combinations of the fuel and oxygen. Combustion reactions occur when oxygen reacts with another substance and gives off heat and light. Burning coal, methane gas, and sparklers are all common examples of combustion reactions. Essentially, any reaction that involves burning something is a combustion reaction.
