Part A
What is the importance of Petrology?
Answer
Petrology is essential in engineering geology for understanding the origin, composition, and structural characteristics of rocks. It helps in evaluating the suitability of rocks as construction materials, foundation sites, and tunneling media, as well as predicting their behavior under stress and weathering.
Write the properties of rock- Granite.
Answer
Granite is a coarse-grained, intrusive igneous rock composed primarily of quartz, feldspar, and mica. Its key properties include high compressive strength, low porosity, high durability, and resistance to chemical weathering, making it an excellent building stone and foundation material.
