Geography is an integral component of the overall Social Sciences syllabus of Class 7. Having a firm grasp on the subject is essential to score good marks in examinations. The discipline entails the study of man–environment relationship, and it helps young minds connect to nature and understand the practicalities of various everyday natural phenomena that they see around them. The fourth chapter of the Class 7 NCERT Geography textbook is titled ‘Air.’
The chapter begins by mentioning that the mass of air, which engulfs the earth and makes it livable, is what we call the atmosphere. The earth's atmosphere is composed of different gases, such as hydrogen, oxygen, carbon dioxide, helium, etc. The chapter then goes on to explain the three important constituents of the earth’s atmosphere and provides fascinating insights on the atmosphere’s structure and on earth’s weather and climate.
Geography is a wonderful subject, and it has an expansive scope vis-à-vis higher studies. However, for young minds of Class 7, the subject may be too cumbersome as the lessons are often very detailed and include complicated concepts. As such, some extra handholding is essential for students to reach their optimum potential. Parents and teachers should ensure that students are going to receive additional academic support via study materials, guidance reports, etc., as depending solely on NCERT textbooks and exercises is not enough.
