Question 6

Kerala's diverse topography and heavy rainfall lead to the formation of various soil types. Among these, laterite soils are prominent. Which of the following statements most accurately describes laterite soils and their agricultural significance in Kerala?

Accepted Answer

B. Formed under conditions of high temperature and heavy rainfall, they are rich in iron and aluminium oxides, suitable for crops like cashew, tapioca, and rubber. — Laterite soils in Kerala are formed due to intense leaching under high temperature and heavy rainfall, leading to a high concentration of iron and aluminium oxides. While generally less fertile due to low organic matter and nitrogen, they are well-suited for crops like cashew, tapioca, and rubber with appropriate soil management practices. Options A, C, and D describe characteristics of other soil types (alluvial, black, and sandy coastal soils, respectively) or misrepresent laterite soil properties and their agricultural uses.

Answer

A. They are rich in humus and nitrogen, making them highly productive for intensive paddy cultivation in low-lying areas.

Answer

C. Characterized by fine particles and high moisture retention capacity, they are ideal for growing cotton and sugarcane in highland regions.

Answer

D. They are porous and sandy, primarily found along coastal plains, supporting coconut and limited vegetable farming due to low fertility.

Question 9

In a Pressurized Water Reactor (PWR), which of the following statements accurately describes the primary function of the control rods and the moderator material?

Accepted Answer

B. Control rods absorb excess thermal neutrons to regulate the chain reaction, while the moderator slows down fast neutrons to thermal energies. — Control rods, typically made of neutron-absorbing materials like cadmium or boron, are used to absorb excess thermal neutrons, thereby regulating the rate of the nuclear chain reaction. The moderator material, such as heavy water or graphite, slows down the high-energy (fast) neutrons released during fission to lower (thermal) energies, increasing the probability of them being absorbed by fissile nuclei and sustaining the chain reaction.

Answer

A. Control rods absorb fast neutrons to slow them down, while the moderator absorbs excess thermal neutrons.

Answer

C. Control rods reflect neutrons back into the core, while the moderator removes fission products.

Answer

D. Control rods increase the rate of fission, while the moderator cools the reactor core.

Question 10
