Ans 1:

SWARIT JAIN from DPS Greater Noida, GREATER NOIDA
Class : Class 9
just because we can see the whole moon during a full moon dosen't mean that on that day there will be the greatest tides as the moon dosen't cut itself into half on 1st and 3rd quarter. So, the answer must depend on the distance of the moon from the earth as the gravitational pull of the moon will have more effect when it is closer to earth and will raise bigger tides. The moon is closest to earth at phases D and H. So, clearly the answer should be A

Ans 2:

Anantjit Chander from Apeejay School, Sector 15, Faridabad

Ans 10:

Jayaditya singh from Delhi Public School, gurgaon
Class : Class 9
It is a fact that the highest tides occur when the moon is full or new. In the diagram, the positions F and J are the full moons and new moons, so the correct answer should be B

Ans 11:
