Learning – difference b/w Sawannah and grasslands, names of grasslands, Koeppen classification

- 2 and 3
- 1 and 3
- None
- See statement 2 was asked in this year’s CAPF exam
- 3rd is factually wrong
- 1 is given in NCERT. It also seems the only plausible reason as rift valley can force the direction
Learning – rivers and tributaries mentioned in NCERTs
- Consider the following statements:
- Natural gas occurs in the Gondwana beds.
- Mica occurs in abundance in Kodarma.
- Dharwars are famous for petroleum.
Which of the statements given above is/are correct?
- 1 and 2

- 2 and 3
- None
- Geologic history of India very important. You can answer all such questions from that.
- It’s common knowledge, Gondwana is famous for coal fields nor natural gas
- Dharwar (Karnataka) has other minerals like iron, manganese not petrol
- Mica occurs in Kodarma <kodarma mines in Jharkhand>
Learning – geologic history of India
- Which of the following is / are the characteristic/ characteristics of Indian coal?
- High ash content
- Low sulphur content
- Low ash fusion temperature
Select the correct answer using the codes given below.
- 1 and 2 only
- 2 only
- 1 and 3 only
- 1, 2 and 3
- High ash ie low quality. Indian coal is low quality. We import coking coal
- Low sulphur is also common knowledge
- But ash fusion temperature is generally not given in books. This statement was wrong. Indian coal actually has high ash fusion temperature
- Which of the following statements regarding laterite soils of India are correct?
- They are generally red in colour.
- They are rich in nitrogen and potash.
- They are well-developed in Rajasthan and UP.
- Tapioca and cashew nuts grow well on these soils.
Select the correct answer using the codes given below.
- 1, 2 and 3
- 2, 3 and 4
- 1 and 4
- 2 and 3 only
- Covered in titbit
- Easy question
- No major soil rich in nitrogen. Exclude 3, only option left is
- 2 is also incorrect as they occur in areas with high rainfall
- Laterite soil is found on western ghats, tapoica and cashews grow there
- Laterite soils are rich in iron and aluminum
Learning – Soils of India, characteristics and geographical spread
- Consider the following crops
- Cotton
- Groundnut
- Rice
- Wheat
Which of these are Kharif crops?
- 1 and 4
- 2 and 3 only
- 1, 2 and 3
- 2, 3 and 4
- NCERT
- Wheat everyone knows is rabi crop – wheat holi
- Eliminate 4
- Now look at 1 – cotton – kharif crop
Learning – Kharif, Rabi, Zaid season
- Consider the following pairs :
- Limboo (Limbu) : Sikkim
- Karbi : Himachal Pradesh
- Dongaria : Odisha
- Bonda : Tamil Nadu
Which of the above pairs are correctly matched?
- 1 and 3 only
- 2 and 4 only
- 1, 3 and 4 only
- 1, 2, 3 and 4
- Tribes are asked but difficult to remember
- Dongaria – Odisha is easy as dongaria kondh tribe was in news due to POSCO project
- Karbi would be of Assam – karbi aunglong protest for separate state
- Exclude 2, include 3. You can eleminate 2 options but you still need to know about 4
- Bonda are the most primitive tribal groups in Odisha
- Variations in the length of daytime and night time from season to season are due to
- the earth’s rotation on its axis
- the earth’s revolution round the sun in an elliptical manner
- latitudinal position of the place
- revolution of the earth on a tilted axis
Simple NCERT question taught in 5th standard that season are due to tilt. Only one option related to tilt
- On the planet earth, most of the freshwater exists as ice caps and glaciers. Out of the remaining freshwater, the largest proportion
- is found in atmosphere as moisture and clouds
- is found in freshwater lakes and rivers
- exists as groundwater
- exists as soil moisture
- 1 and 4 can be easily excluded as they would be very low percentage
- B/w lakes and rivers v/s ground water, simple logic suggests, even lakes and rivers replenish ground water reserves so that should be more
- In any case it is taught in 7th – 8th Std. Ground water >>>> river lake water
- During a thunderstorm, the thunder in the skies is produced by the

- lightning that separates the nimbus clouds
- violent upward movement of air and water particles
Select the correct answer using the codes given below.

- Once then light is gone the air collapses back in and creates a sound wave that we hear as thunder.
- The reason we see lightning before we hear thunder is because light travels faster than sound!

- The annual range of temperature in the interior of the continents is high as compared to coastal areas. What is / are the reason / reasons?

- Presence of strong winds in the interior
- Heavy rains in the interior as compared to coasts.
- 1 only
- 1 and 2 only
- 2 and 3 only
- 1, 2, 3 and 4
- Similar question was asked in CAPF this year. Maximum annual range of temperature
- You know 1 is correct Ie Continentality difference in specific heat, thermal difference
- Statement 2 is a bogus statement, what does altitude has to do with any of that
- Exclude 2, include 1
- Statement 4 is also wrong, not heavy rainfall in interior but less rain fall in interior
Learning – continentality, sea breeze – land breeze
- Consider the following:
- Electromagnetic radiation
- Geothermal energy
- Gravitational force
- Plate movements

Which of the above are responsible for bringing dynamic changes on the surface of the earth?
- 1, 2, 3 and 4 only
- 1, 3, 5 and 6 only
