I also want to know that why most of the USP questions are not included in theory books

Yes Vishal, I understand your concern. The theory book is very concise and can't include everything. Theory book has been prepared for understanding the core concepts that you need to grasp. If you will get the answer of all USP questions in theory book then there is no meaning of practicing question. After studying the theory book you should develop your own concepts and attempt the USP question.

Dear student, ole follow the given steps for preparing the topic "distribution of rocks". 1. First understand what's the basic definition of any rock and read about rock cycle. Rock cycle explains the origin and transformation of one rock type to other. 2. Understand the classification of rocks (igneous, sedimentary and metamorphic) and read about characteristic mineral assemblages. For eg mafic igneous rocks are mainly composed of minerals like Pyroxene, olivine, plagioclase etc. and felsic igneous rocks are dominantly composed of mineral like quarts, alkali feldspars etc. 3. Understand the origin of rock and try to think the places where you can get that rock; for eg. you can get igneous rocks nearby volcanoes, MORs, mantle plumes or any previously emplaced rocks 4. Read about the basic characteristics of subtypes in a particular rock and try to learn about there paragenesis; for eg, Quartz Arenite is a sedimentary rock formed by intense weathering/leaching conditions and prolonged transportation 5. For more details, look at the Indian Stratigraphy and try to look at very important rock Groups.
