The force causing the change in the shape of rock is called stress. The change of shape in the rock is called strain. If the stress does not cause a permanent change in the shape of rock, it is called elastic deformation. If the change is permanent, it is called plastic deformation.
While rubber was originally made from the sap of the rubber tree, and was thus a renewable resource, most modern products called "rubber" are made from chemicals derived from petroleum and thus are not renewable resources.
The vulcanization of rubber is a chemical process where you convert rubber, or other related polymers, into a more durable material by way of the addition of sulfur. The reason why you can not use any other element to do this is because other elements do not produce the same results.
Rubber in natural form is a long polymer with a strong tendency to swallow and a very small capability to maintain its form in front of temperature changes. As all polymers it is formed by very long chains formed by repetition of the same molecule, called the monomer. The chain can be cross linked by introducing chemical bonds either between different parts of the same chain or between different chains. By cross linking natural rubber with sulfur (a process called vulcanization) the rubber becomes much more elastic, that is able to return to its original shape after deformation, and much more resistant to temperature changes. This means that a chain of three sulfur atoms are structured like a bridge bonding different parts of a chain or of different chains. At 2 to 3% cross linking a soft rubber, that no longer suffers stickiness and brittleness problems on heating and cooling, is obtained. At 25 to 35% cross linking a rigid hard rubber product is formed.
Hi there :D Rubber is a hydrocarbon therefore hydrogen and carbon. Also some rubber is hardened. This is called vulcinisation and it uses sulphur. If you would like a free lecture on this or just dancy a chat do not hesistate to call: 07801511359 Many thanks James Cockerton
Soil can indeed be considered a non renewable resource. This is because the process to replace it takes a lot of years.

Elastic, rubber or a rubber band can be stretched and hen returns to its own shape.
Rubber band, garter, rubber.................................................................understand
From the plant - "tapping" rubber sap.
A stretched rubber band is potential energy because the energy is stored.
If a rubber band is stretched, it has elastic energy.
It won't stick when the rubber is stretched.
Because, like a rubber band, it can be stretched until it can't be stretched anymore. When the rocks cannot be stretched anymore, the fault breaks and slips as earthquakes.
When a rubber band is stretched, it has potential energy. Any type of stored energy is known as potential energy.
Rubber is actually made from latex which is a form of silicon. Rubber bands are a polymer that can be stretched.
