Environmental science has been introduced as a course work at the undergraduate level by all the universities of higher studies. This course material has prompted the editor to have an insight and deeper understanding to strengthen the concepts on core topics by interacting in this seminar in the field of Applied Geo-environmental Studies at the micro level to reach the objective and goal. The book "Science of Weather and Environment"has been divided into fifteen chapters. Attempt has been made in this book to introduce to the readers the important aspects of weathers and environment. A conceptual environmental exploration strategy has also been attempted in this book, distilling the knowledge gained from three decades of exploration. This book is suitable for geophysicists, geologist, scientists, universities, organizations, teachers, students and other working in different disciplines of petroleum science and engineering. This book will serve to readers and users as reference books."
