What is asbestos?

Asbestos is indeed a naturally occurring mineral that can be found in various rock formations. Its unique property lies in its ability to be separated into very fine and flexible fibers, which makes it useful in numerous industrial applications, particularly in construction and insulation. These fibers are not only resistant to heat and fire but also have sound absorption properties, which historically led to widespread use in building materials.

The understanding of asbestos' fibrous nature is crucial, as it highlights the health risks associated with inhaling these fibers, which can cause serious respiratory diseases, including asbestosis and lung cancer. The other options refer to materials or substances that are not related to the true characteristics of asbestos, as they either describe synthetic compounds or products not made from naturally occurring minerals.
