sedimentary rocks and so are considered mineral resources. All three must be refined in order to be used in making plastic. All mineral resources are non-renewable, so it’s very important that they are conserved. We can conserve our minerals resources by using the products we buy for a very long time, by passing on the things we no longer need

A rock is a naturally occurring solid mixture composed of minerals, smaller rock fragments, organic matter, or glass. The individual particles in rocks are called grains. The mineral grains in rocks give clues to understanding how the rocks ...
