4-The Indian Ocean Dipole (IOD) is the temperature differential between the eastern (Bay of Bengal) and western Indian Oceans (Arabian Sea).

13-Madden The Julian Oscillation (MJO) is a cloud, wind, and pressure disturbance that moves eastward at a speed of 4-8 metres per second. On average, the MJO travels around the world every 30-60 days. It can take up to 90 days at times.

21- Every year, between 70 to 90 cyclonic systems form around the world. The wind spirals around a low-pressure area due to the Coriolis force.

22-Hurricane Ida recently made landfall in Louisiana, United States. It is a Category 4 storm, one of the most powerful storms to ever impact the United States.

23- A glacial lake is a body of water formed by glacier activity. They arise when a glacier erodes the terrain and then melts, filling the resulting depression.

24-The earthquake measuring 6.4 on the Richter Scale originated near Sonitpur, Tezpur, Assam, according to the National Centre of Seismology.

25-A landslide occurs when a pile of rock, rubble, or earth slides down a hill. Landslides include five types of slope movement: falls, topples, slides, spreads, and flows.
