Class : Class 5
how is it b, it should be a

Ans 2:

Class : Class 5
i have done this question and they are showing b

Ans 3:

Class : Class 7
It should be B only .

Ans 4:

Class : Class 10
It is (A)

Ans 5:

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 6:

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 7:

Class : Class 8
It is B. Don't go on the picture. Full and new moon are always closer to Earth.

Ans 8:

Class : Class 10
Phases D and H are suitable. Or not?😄

Ans 9:

Class : Class 9
Answer is B only.

Ans 10:

Class : Class 7

Ans 11:

Class : Class 5
d and h are only the answers..

Ans 12:

Class : Class 9
Ohh yeah,, it is A

Ans 13:

Class : Class 5
the correct option is b

Ans 14:

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 15:

yes, the correct answer is D since there are two belts of low pressure on the earth. on the equator (due to high temperature) and between the two belts of high pressure (60 degrees North and South. ). A cannot be the correct answer.
