The fall of meteorites to the Earth's surface is part of the continuing process of accretion of the Earth from the dust and rock of space. When these rock fragments come close enough to the Earth to be attracted by its gravity they may fall to the Earth to become part of it.
Vulcanized Rubber. Vulcanized rubber is a material that undergoes a chemical process known as vulcanization. This process involves mixing natural rubber with additives such as sulfur and other curatives.Vulcanization makes rubber much stronger, more flexible, and more resistant to heat and other environmental conditions.ulcanized rubber is also more rigid than non-vulcanized rubber, so it is more stretch-resistant in the first place. However, vulcanized rubber has the same elasticity level as non-vulcanized rubber.
During the same period a British coachman cut rubber into strips and created the rubber band. The most significant discovery during that period was that of Charles Goodyear. He introduced Sulphur Dust into rubber and discovered Vulcanization. Vulcanized Rubber gives natural latex resistance to temperature extremes. This gave birth to our vast tire industry. In fact, in 1846, the tires of Queen Victoria's coach were made from Rubber.
