Ansh Meshram from Fr agnel School, New Delhi
Subject :NSO    Class : Class 8

The semi-arid plains of a particular region show a pattern of alternating yellow and black stripes on the ground. The yellow stripes consist of land covered by ripening wheat. The black stripes are bare soil on which no crop is grown but farmers use herbicides or tillage to remove any weeds that try to grow in that region.
Why do farmers in this region manage soils in this way?

A Farmers put the half of their land to rest for minimising erosion and soil degradation.
B Farmers discourage transpiration in the wheat plantation by allowing free evaporation from the soil of the bare stripes.
C Farmers try to store some part of one year’s rainwater in the soil under the bare stripes and use that water to supplement the rain on wheat crop planted the next year.
D All of these

Class : Class 6
It is B. Don't go on the picture. Full and new moon are always closer to Earth.

Ans 3:

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 7:

SWARIT JAIN from DPS Greater Noida, GREATER NOIDA
Class : Class 8
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 8:

Anantjit Chander from The Modern School, Sector 85, Greater Faridabad, Faridabad

Jayaditya singh from Delhi Public School, gurgaon
Class : Class 6
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 24:

Anantjit Chander from The Modern School, Sector 85, Greater Faridabad, Faridabad
