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 7:

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

Ans 8:

Class : Class 8

Ans 9:

Class : Class 5
the correct option is b

Ans 10:

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 11:

Class : Class 8
Class:It should be A

Ans 12:

Class : Class 5

Ans 13:

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

Ans 14:

Class : Class 7

Ans 15:

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

Ans 16:

Class : Class 7
It should be B only .

Ans 17:

Class : Class 7
B is the answer to this question

Ans 18:

Class : Class 9

Ans 19:

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 20:

Class : Class 6
I do with Harsh Sobti.

Ans 21:

Class : Class 10
It is (A)

Ans 22:

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

Ans 23:

Class : Class 10

Ans 24:

Class : Class 9
Ohh yeah,, it is A

Ans 25:

Class : Class 7

Ans 26:

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.

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.

Ans 24:

Class :
The answer is D as low pressure exists in both equator and 60 degree north and south.

Ans 25:

Class : Class 8
Answer should be D only . There is low pressure at the equator and at 60 degree north and south pole
