Dynamite is an explosive by mixing many chemicals. These chemicals burst with lots of pressure and heat. So, an explosive can be very dangerous as it can destroy everything that is present around it. Dynamite was used in wars. But now it is mainly used in quarrying and mining. Here, huge blocks of rocks or small hills are brown. It is done to extract minerals and that's are inside the earth. It is also used in construction and demolition where a building or a structure is blown away to create flat grounds or to make passages for roads and dams. Before dynamite got its name, it was called “Noble’s blasting powder” as it was invented by Alfred Nobel.
