Explanation:

Igneous Rocks:-

Many types of igneous rocks are used as building stone, facing stone, and decorative material, such as that used for tabletops, cutting boards, and carved figures. Pumice is used as an abrasive material in hand soaps, emery boards, etc.

Sedimentary Rocks:-

Sedimentary rocks are economically important in that they can easily be used as construction material because they are soft and easy to cut. Sedimentary rocks often form porous and permeable reservoirs in sedimentary basins in which water and important minerals such as oil can be found.

Metamorphic Rocks:-

Metamorphic minerals and rocks have economic value. For example, slate and marble are building materials, garnets are used as gemstones and abrasives, talc is used in cosmetics, paints, and lubricants, and asbestos is used for insulation and fireproofing.

Answer 2

Rocks are of three types: igneous, sedimentary and metamorphic. Each rock type has its own features and characteristics. Igneous rock is hard and fossil free whereas sedimentary rock is fossiliferous and soft and metamorphic rock is very hard.

Explanation:

• Economic importance of igneous rock: Granite is used for making pencil lead, graphite etc, floor making etc.
• Sedimentary rock : Limestone, Sandstone, Shale are used as building materials and for making chalk as contains CACO3.
• Metamorphic rock : Marble, Quartzite are very hard rock so used as good quality building material, railway coaches etc.
