CMAT 2025 Slot 1 Question Paper

(A) The crust of the Earth comprises rocks rich in Silica and Aluminium. This is CORRECT. The Earth’s crust is primarily made of silicate rocks containing elements like silicon and aluminium, often referred to as sial.

(B) The core of the Earth consists of metals in a liquid state at high temperature and pressure. This is CORRECT. The outer core is liquid, mainly composed of iron and nickel, while the inner core is solid despite high temperatures due to immense pressure.

(C) Magnesium and Phosphorus are dominant in the core of the Earth. This is NOT CORRECT. The core is dominated by iron and nickel, not magnesium or phosphorus, which are more abundant in the mantle and crust.

(D) The Hydrosphere covers approximately 71% of the total surface area of the Earth. This is CORRECT. About 71% of the Earth’s surface is covered by water, forming the hydrosphere, while the remaining 29% is land.

(A) Bandipur National Park is located in Kerala. This is NOT CORRECT. Bandipur National Park is in Karnataka, not Kerala, and is famous for its tiger reserve.

(B) Jim Corbett National Park is located in Uttarakhand. This is CORRECT. It is India’s first national park, established in 1936, and is located in Uttarakhand, known for its Bengal tigers.

(C) Dudhwa National Park is located in U.P. This is CORRECT. Dudhwa National Park is in Uttar Pradesh, situated along the Indo-Nepal border, known for swamp deer and tigers.

(D) Gir National Park is located in Rajasthan. This is NOT CORRECT. Gir National Park is in Gujarat, and it is the only natural habitat of the Asiatic lion.

Wankhede Cricket Stadium is located in Mumbai, Maharashtra. It is one of India’s most famous cricket stadiums and has hosted numerous historic matches, including the 2011 ICC Cricket World Cup final.

The blue colour of the sky is due to the scattering of light by gas molecules and particles in the atmosphere. Sunlight contains all colours, but the shorter, blue wavelengths are scattered more effectively in all directions than longer wavelengths like red, which is why the sky appears blue to us.

(A) Article 14 -> (III) Equality before law

Article 14 of the Indian Constitution is a Fundamental Right that guarantees to every person Equality before law and Equal protection of the laws within the territory of India. 

(B) Article 21 -> (I) Protection of life and personal liberty

Article 21 is a crucial Fundamental Right which states that no person shall be deprived of his life or personal liberty except according to procedure established by law. 

(C) Article 24 -> (II) Prohibition of employment of children in factories

Article 24 falls under the Fundamental Rights against Exploitation and specifically mandates the Prohibition of the employment of children in factories, mines, or any other hazardous employment. 

(D) Article 50 -> (IV) Separation of judiciary from executive

Article 50 is a Directive Principle of State Policy (DPSP) that requires the State to take steps to separate the judiciary from the executive in the public services of the State. This separation is vital for ensuring the independence of the judiciary and its ability to function without undue influence from the executive branch.

A) Electrical Energy into mechanical energy -> (III) Electric motor

The electric motor is a device that converts Electrical Energy into mechanical energy. It uses the force produced by an electric current in a magnetic field to cause rotation, which performs mechanical work.

(B) Electrical Energy into Light energy -> (II) Tube light

A tube light (fluorescent lamp) converts Electrical Energy into Light energy (and heat). Electric current excites the gas inside the tube, causing it to emit UV light, which then excites the phosphorus coating to produce visible light.

(C) Mechanical Energy into Electrical Energy -> (I) Dynamo

A dynamo (a type of electric generator) converts Mechanical Energy into Electrical Energy. It works on the principle of electromagnetic induction, where a rotating coil in a magnetic field generates an electric current.

(D) Solar energy into electrical energy -> (IV) Solar cell

A solar cell (photovoltaic cell) converts Solar energy (light energy) into electrical energy. It uses the photovoltaic effect, where light shining on certain materials creates an electric current.

(A) White Revolution is related to Milk production. This is CORRECT. It is related to milk production. It was a major dairy development program in India, also known as Operation Flood, that transformed the country from a milk-deficient nation into the world's largest milk producer.

(B) Black Revolution is related to Honey production. This is NOT CORRECT. It is related to increasing petroleum and crude oil production to achieve self-sufficiency in the energy sector. It is also associated with biodiesel production through the blending of ethanol with gasoline.

(C) Blue Revolution is related to leather production. This is NOT CORRECT. It is related to fisheries and aquaculture, focusing on increasing fish and aquatic organism production and productivity from both inland and marine sources.

(D) The Yellow Revolution is related to oilseed production. This is CORRECT. It is related to the production of oilseeds, with the primary goal of achieving self-sufficiency in edible oils in India. 

Therefore, (A) and (D) are the only correct statements.

The soil formed by the weathering of a crystalline and metamorphic mixture of clay and sand is Red soil. It is characterised by its high iron oxide content, which gives it its reddish colour. This weathering process primarily occurs on crystalline and metamorphic rocks.

Alluvial soil is formed from the deposition of silt, sand, and clay carried by rivers. It is typically found in river plains and deltas.

Black soil is formed from the weathering of volcanic rocks, particularly basaltic lava flows. It is rich in clay minerals and has a high water-holding capacity.

Laterite soil is formed in tropical areas with high temperatures and heavy rainfall. It is rich in iron and aluminium oxides due to intense leaching.

(A) Temperature -> (III) Kelvin (K)

Temperature is a fundamental physical quantity that measures the degree of hotness or coldness of a body. Its SI unit is the Kelvin (K). 

(B) Mass -> (I) Kilogram (kg)

Mass is a fundamental physical quantity that measures the amount of matter in an object. Its SI unit is the Kilogram (kg). 

(C) Electric current -> (IV) Ampere (A)

Electric current is a fundamental physical quantity that measures the flow of electric charge. Its SI unit is the Ampere (A). 

(D) Length -> (II) Meter (m)

Length is a fundamental physical quantity that measures the extent of an object or the distance between two points. Its SI unit is the Meter (m). 

The first Chief of Defence Staff (CDS) of India, General Bipin Rawat, tragically died in a helicopter crash on 8 December 2021 in Tamil Nadu. He was a highly respected military leader, serving as the head of India’s armed forces and playing a key role in modernising the military structure.
