Hi students! In Chapter 5, we learn about water and its importance. Water is everywhere – in rivers, ponds, and oceans. We have learned about the water cycle, which keeps water moving between the land, oceans, and atmosphere. The ocean water is salty because it has dissolved salts. We studied how ocean water moves continuously, forming waves, tides, and currents. Tides are caused by the gravitational pull of the sun and moon. In chapter 5 of the NCERT’s book, we understand how water is essential for life and keeps our planet working smoothly.
Once you have read the chapter thoroughly, try to attempt the 20 MCQ questions below. Further, you can take up the 10 fill-in-the-blanks questions.
