Final answer:
Building and paving materials are made from rocks and the minerals that constitute them, with natural stone like granite and limestone being common, alongside man-made products like Portland cement. option C is the correct answer.
Step-by-step explanation:
The materials used to manufacture building and paving materials are primarily rocks and the minerals that compose them. Rocks such as granite, which can consist of a combination of minerals like quartz, feldspar, and mica, are commonly used. There are three basic types of rocks found in nature: igneous, sedimentary, and metamorphic. For instance, limestone, a sedimentary rock, is composed mainly of the minerals calcite and aragonite and has been a popular building material throughout history. In addition to natural rocks, man-made materials such as Portland cement, which contain silicates derived from various minerals, are essential in construction.
The materials used to manufacture building and paving materials are rocks. Rocks are made up of different combinations of minerals, which are the basic building blocks of rocks. For example, granite is a type of rock that is made up of a combination of minerals.
