Q4.How are waves generally formed on the ocean surface?

A. By the gravitational pull of the moon. B. When winds scrape across the ocean surface. C. Due to underwater volcanic eruptions. D. By the movement of large marine animals.

Q5.Besides earthquakes, what other natural phenomena can cause a tsunami according to the provided text?

A. Heavy rainfall and floods. B. Strong ocean currents and tides. C. Volcanic eruptions or underwater landslides. D. Cyclonic storms and hurricanes.

A. From 100-200 km/hr to less than 10 km/hr B. From 300-500 km/hr to less than 30 km/hr C. From 700-900 km/hr to less than 70 km/hr D. From 1000-1200 km/hr to less than 100 km/hr

Q7.Based on the information provided, what is the difference in predictability between earthquakes and tsunamis?

A. Both earthquakes and tsunamis can be predicted with a three-hour notice. B. Earthquakes can be predicted in advance, but tsunamis cannot. C. While earthquakes cannot be predicted in advance, it is possible to give a three-hour notice for a potential tsunami. D. Neither earthquakes nor tsunamis can be predicted in advance.

Q8.Why are tsunamis considered rare in the Indian Ocean compared to the Pacific, according to the provided text?

A. Due to deeper ocean trenches in the Indian Ocean. B. Because of higher water temperatures in the Indian Ocean. C. As the seismic activity is less in the Indian Ocean. D. Due to the presence of more islands that dissipate wave energy.
