1. Consider the statements regarding red and yellow soils.
1. Soil looks yellowish when iron diffused in the soil gets hydrated.
2. Red and yellow soils are mainly found in the deltaic regions especially in the Eastern Indian coast.
3. Less fertile coarser soils are found in the uplands while fertile fine soils occur in the< low lying regions.
Which are the correct statements?

1 only. 1, 2 only. 1, 3 only. 2, 3 only.

2. Consider the following statements regarding a particular soil
1. Found in the summits of Western Ghats, Eastern Ghats, Vindhyas, Sathpuras and Malwa plateau.
2. Subjected to intense leaching and thus not fit for agriculture unless manures and fertilizers are used.
3. It is the end product of weathering process and thus it is indefinitely durable.
Which is the soil that is spoken about in the above statements?

Forest soil. Mountain Soil. Laterite soil. Red soil.

3. The soil salinization occurred due to irrigation is a concern in drier regions and not in humid regions. Consider the following statements
1. In humid regions, there is enough precipitation to leach (wash) the salts below the plant root zone.
2. In drier regions, higher temperature leads to higher evaporation of water resulting into leaving behind of salt on the surface of the soil.
3. Soil salinization occurring due to irrigation can equally impact both humid areas as well as drier areas.
Choose the correct statement from the code given below

1, 2 only. 1 only. 2 only. 3 only.

4. Laterite soils and Forest soils are acidic in nature. What is the reason for this?

High rainfalls leach away the cations into sub soil region. Trees and plants absorb the cations necessary for their development. Cations are washed away along with running water and drained into sea/ocean. None of the above reasons are correct.

5. rivers forms many outstanding features throughout their course. In this respect which of the following pairs are correctly matched ?
1. river capture : middle course
2. meanders : upper course
3. ox-bow lakes : lower course
Select the correct answer using the codes given below.

1 and 3 only 1 and 2 only 3 only 2 and 3 only

6. Kerala largely has laterite soil and not red soil. Sugarcane grown in subtropical region has lower productivity than that is grown in tropical regions.
Consider the following statements about subtropical region ie Northern India which has low productivity in sugarcane production.
1) Frost formations.
2) Floods and water logging.
3) High diurnal temperature.
4) Low humidity.
Choose the correct reason/s from the codes below.

1, 2 only. 2, 3 only. 3, 4 only. 1, 2, 3 only.

7. In India El Nino can have comparatively lesser impact on Sugarcane and Urad production.
What are the reasons?
1) Sugarcane is largely grown under irrigated areas.
2) Urad is mainly grown in regions where rainfall variability is very low.
3) Urad is drought resistant crop.
4) Sugarcane although a khariff crop requires very less water.
Choose the right pair of reasons from the codes below

1, 2. 1, 3. 2, 4. 3, 4.

8. The lower gangetic plain is characterised by humid climate with high temperature throughout the year. Which one among the following pairs of crops is most suitable for this region?

Paddy and cotton Wheat and Jute Paddy and Jute Wheat and Cotton

9. Tea best grows in Assam, Darjeeling and Jalpaiguri districts of West Bengal. What is/are the uniqueness of this region which suits this crop?
1) It has warm and humid climate.
2) Showers are mainly concentrated in 4-5 months ie June to October in any year.
3) Deep, fertile and well drained soil.
4) Rugged topography of the relief near the Himalayan foot hills.
Choose the correct code.

1, 2, 3 only. 1, 3 only. 1, 3, 4 only. All the above.

10. With reference to monsoon of eastern Asia and southern Asia, consider the following statements:
1. Winter monsoon in eastern Asia is stronger than summer monsoon while it is the opposite in southern Asia.
2. The burst of monsoon over southern Asia is associated with turbulent weather whereas that in east Asia is characterized by mild weather disturbances.
Which of the statements given above is/are correct?

1 only 2 only Both 1 and 2 Neither 1 nor 2
