Detailed explanation-1: -Stone is a nonrenewable resource; like fossil fuels. By definition, a nonrenewable resource is something that is being used at a faster rate than the rate at which it can regenerate. While stone can regenerate, it takes millions of years for the regeneration process to happen.

Detailed explanation-2: -What is Natural Stone? “Natural Stone” refers to a number of products quarried from the earth, used over many thousands of years as building materials and decorative enhancements. These products include Granite, Marble, Limestone, Travertine, Slate, Quartzite, Sandstone, Adoquin, Onyx, and others.

Detailed explanation-3: -Limestone and sandstone are known as the most common rock types for building walls, while granite is still praised as one of the most popular building materials for both exterior and interior uses. Granite is quite popular as a pavement stone, but also for making monuments, kitchen counters, buildings and gemstones.

Detailed explanation-4: -Uses of stone Buildings, walls, paving slabs. Aggregates – stone used for its strong physical properties – crushed and sorted into various sizes for use in concrete, coated with bitumen to make asphalt or used ‘dry’ as bulk fill in construction. Mostly used in roads, concrete and building products.

Detailed explanation-5: -The three main types of natural stone found on earth are igneous, sedimentary and metamorphic; this classification is dictated by how the stone was formed over the course of the years – or millennia – and gives us interesting and useful insights on the qualities of that specific natural stone.
