7. Name the type of rocks which are considered good for using as building material.
Answers
Explanation:
Igneous rocks are good for building material because they are hard, strong and give a good finishing eg. Granite.
Answer:
Many types of stones are available such as basalt, marble, limestone, sandstone, quartzite, travertine, slate, gneiss, laterite, and granite which can be used as construction materials. The stones used for building construction should be hard, durable, tough, and should be free from weathered soft patches of material, cracks, and other defects that are responsible for the reduction of strength and durability. Stones for construction purposes are obtained by quarrying from solid massive rocks.Function. Vitamin A helps form and maintain healthy teeth, skeletal and soft tissue, mucus membranes, and skin. It is also known as retinol because it produces the pigments in the retina of the eye. Vitamin A promotes good eyesight, especially in low light.Each type of stone lend itself to various construction applications based on its properties. For instance, certain types like basalt and granite have superior characteristic like high compressive strength and durability and hence employed in major construction works. However, there are stones that their characteristics (such low compressive strength and presence of deleterious materials in their constituents) makes them suitable for minor construction works for example gneiss. So, stones are used as building material and also for decorative purposes.Types of Stones Used for Building Constructions
