Akshaj Gupta from Neerja Modi School, Jaipur
Class : Class 7
Class:It should be A

Ans 8:

Divyanshi from United international School, Bangalore
Class : Class 6
The answer is (a) because when the full moon and new moon are there then the sun, earth and moon are aligned and the sun is also pulling at the sea forming big tides.

Ans 13:

Anantjit Chander from Apeejay School, Sector 15, Faridabad
Class : Class 10
Look at the diagram.........the faces of moon closest to the earth are D and H, hence the suitable solution is A

Ans 14:

Gayatri Iyer from Sanskriti School, Pune
Class : Class 9
Ohh yeah,, it is A

Ans 15:

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 16:

Gauransh Singla from DPS , Navi Mumbai
