Questions for Sec 2 MR (CA3)

Hi guys from 2-5 & 2-9,

Below are some questions posted by your peers and might be useful for revision if you need it. The newer questions at the top and the older ones at the bottom. Cheers! Hope mugging for Geo, Sci and Maths have been well over the weekend.

I don't understand chap 3 revision paper, qn4. (Ben 2-9)

For this questions, first you need to know what is the sequence of of the different settlements. the first type of settlement that is very common and can be found mostly everywhere is your villages.That is why they form the base of the pyramid, because in terms of absolute number of village settlements, there are many, but the size of the village settlement is small.

Next, when many small village settlements group together, they form a town, so that is why they form the middle part of the pyramid. There are not as much towns found as compared to villages BUT the size of a town as a settlement, is larger than that of a village settlement.

Lastly, many towns form your city, and that is why it is at the top of the pyramid. The number of cities is lesser than that of a town or village found in the world, but the size of a city is very much larger than that of a town and village.

For instance, Blk 451, Blk 452 of bishan street 22 forms your villages, together, they form Bishan Town, then, AMK town, Bishan Town, Pasir Ris Town, Telok Blangah Town etc, all the towns in Singapore form your Singapore City. There are many many blocks (villages) in Singapore, fewer number of Towns, and there is only one City (Singapore).

Hope this illustration helps.

Chapt 4 revision paper, qn 10,why the answer is D and not C? (Wei Yang 2-9)

A Water that floods the fields has been treated.
B More fertilisers have been added to the slopes as there is much soil erosion.
C The slopes have been flattened to allow crops to be grown.
D Steps have been cut into the slopes to create flat land.

Wei Yang, the picture shows a land which is not flat, probably a hill. It shows terraces, which mean, the original, sloped land has been cut into the step like terraces you see in the picture, thus answer has to be D and not C.The slopes are not flattened, if it is flattened, then you would not see steps at all.

Miss zheng, what do u call a pyramid that has bulging top, normal middle, and a thin bottom? (Yikai 2-5)

2-5 Wayne: inverted pyramid? (Yes it can be called an inverted-like pyramid)
But it really depends on what it looks like, so depends on what the diagram shows. If you really cannot decipher the shape, then I advise for you to describe the shape.

In chp 4 revision paper ques 9, why is 'B' the answer and not 'C'? And for ques 11, why is the answer 'A' and not 'C'? (Kang Qiao 2-5)

For Qn 9, answer is B, as inputs for wet rice is not as much as compared to C. First you eliminate the answers A & D as output per land area is low in this two but wet rice output per land area is high. So answer can only be B or C. But for C, it’s a better answer for high tech farming where inputs are very high (esp capital) & land area very small. B is a better answer as inputs are not as much as high tech farming and the land area is not as small as high tech farming, so B is a better answer to choose for Wet rice cultivation and I would say ans B is for High tech farming.

What’s the difference between factors and reasons.(Yuren 2-5)

Depends on the questions, they are quite similar. but factors in population u gt to think about BR, DR, Immigration rate, Emigration rate etc. reasons, tend to be longer answers and are elaborated.

What are some of the components of the human environment? I. %9The people occupying an area II. %9The movement of people or goods from one place to another using vehicles %9III. %9The growing of cr err in the 1st revision paper 2nd quetion, why is the answer C? shouldnt burning fossil fuels be also human activity? (Yi Kai 2-5)

COMPONENTS of Human environment. Still remember PSATC?Population, Settlement, Agriculture, Transport & Communication. So ans is C.
I. The people occupying an area (Settlement)
II. The movement of people or goods from one place to another using vehicles (Transport)
III. The growing of crops (Agriculture)
IV. The burning of fossil fuels (Human ACTIVITY not COMPONENT)

What is grid settlement? (Kang Qiao 2-5)

Grid settlement is more like how a town is being planned, like a grid. You need not know that , you just need to know only what is a dispersed, linear and nucleated settlement.

How are wet rice cultivated on hill sloped irrigated? (Kang Qiao 2-5)

Hills are cut into terraces, mud walls called bunds are built & then they are flooded in order to grow WET rice. They are irrigated like on normal flat land through irrigation canals built alongside the slope. natural rainfall can also flood the terraces.

May i ask why is it that for shifting cultivation, only small land is needed? And for plantation agriculture, are the felled trees burned?(Kang Qiao 2-5)

Small land is needed as shifting cultivation is for subsistence, but large forest land is cleared as it would be easier to clear a large land area first so that the family need not have to do the labourious work of having to clear again the next time they shift to a new area to grow crops. For plantation agriculture, yes, felled trees are burnt also for the reason as a source of fertilizer or nutrient. It also makes the work easier for plantation when burning is carried out as weeds, or competing plants will be rid off already.

Hey miss zheng, may i know how to explain for fluctuating trend? Like do u write increasing in a fluctuating trend? or decreasing? since fluctuating is up and down both? (Yikai 2-5)

Flunctuating trend, the characteristic is that it goes up and down. If the values overall goes up, you say fluctuating increasingly, though it is going up n dwn.unless its constant across, its just fluctuating up and down (no increasing or decreasing)
