The mineral that is used to make cement and fertilizer is limestone. So, the correct option is D.Limestone is a sedimentary rock that contains calcium carbonate. It is used in the manufacturing of cement and fertilizer. Calcium carbonate decomposes in the process of calcination to form calcium oxide and carbon dioxide.
6,500 pounds of cement; 82,000 gallons of petroleum. As each of us use the Earth's natural resources on a human time scale, it is important to consider that mineral resources form on geologic timescales, and the vast difference between the two. The items in this case are just a few of the ways that we use rocks and minerals in our everyday lives.
