BPSC TRE 1 PYQ Quiz – Higher Secondary Teacher Exam Subject Geography

Explanation: Industrialization is defined by the transition from hand production methods to machines and factory systems.

Explanation: The Human Development concept was developed by Mahbub ul Haq and notably expanded/popularized by Amartya Sen.

Explanation: Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

Explanation: Definitions of urban and rural areas vary globally and often involve multiple criteria including population size, density, and economic activity (agriculture vs. non-agriculture).

Explanation: The Bundelkhand region is divided between the states of Uttar Pradesh and Madhya Pradesh.

Explanation: The Planning Commission utilized multiple factors including topography, soil, geological formation, climate (rainfall/temperature), and cropping patterns.

Explanation: Tertiary activities constitute the service sector, providing services rather than goods.

Explanation: Fertile alluvial plains usually support high population density, leading to compact or nucleated settlements.

Explanation: Overcrowding leads to negative outcomes such as strain on infrastructure, pollution, and the development of slums, which contradicts the positive options provided

Explanation: The Sundarbans mangrove forest is the primary habitat of the Royal Bengal Tiger in India; Gir is famous for lions.

Explanation: Statements A, B, and C are all geographically correct regarding the Karakoram range.

Explanation: Both Punjab and Haryana have seen significant declines in fertility and mortality rates, though Punjab is further along; “More than one” is the most inclusive answer.

Explanation: World Nature Conservation Day is celebrated on July 28th.

Explanation: Urban degradation is a result of multiple factors including vehicular emissions, SPM, and various pollutants.

Explanation: Human habitation exists in the high Arctic (e.g., Alert, Canada; Ny-Ålesund, Svalbard) extending to roughly 80 degrees North.

Explanation: Approximately 10-11% of the world’s land surface is arable and under permanent crop cultivation.

Explanation: The Kakrapar Atomic Power Plant is located in the state of Gujarat.

Explanation: Ramgarh Vishdhari Tiger Reserve is located in Rajasthan.

Explanation: Koraput in Odisha is famous for its rich Bauxite deposits; Khetri is known for Copper.

Explanation: These iron ore mines are located in the West Singhbhum district of Jharkhand.

Explanation: These regions receive heavy rainfall, supporting Tropical Evergreen forests.

Explanation: NFSM stands for National Food Security Mission, a central scheme in India.

Explanation: Bajra (Pearl Millet) is a hardy crop that grows well in drought conditions and poor soil.

Explanation: The proposal was moved by India.

Explanation: A natural region is defined by the uniformity of natural features like relief, climate, and vegetation.

Explanation: The Shivalik range is known by different names locally; the Abor, Miri, and Mishmi hills are in Arunachal Pradesh.

Explanation: Alfred Hettner defined geography as a “chorological” (study of places/regions) science; the question text likely contains a typo for “chorological,” making Hettner the intended answer.

Explanation: Volcanic eruptions are caused by a combination of magma formation, gas pressure buildup, and tectonic plate interactions.

Explanation: Karst topography is formed by the dissolution of soluble rocks (like limestone), creating sinkholes (dolines) and caves.

Explanation: Monsoons are defined by a seasonal reversal in wind direction caused by differential heating of land and sea.

Explanation: The subpolar low-pressure belts are located at approximately 60 degrees North and South latitude.

Explanation: Orographic rainfall occurs when moist air is forced to rise over a physical barrier such as a mountain range.

Explanation: The water cycle distributes heat (latent heat), regulates atmospheric moisture, and impacts ocean salinity through evaporation and precipitation.

Explanation: These extensive underwater mountain chains are specifically called “Mid-Ocean Ridges.”

Explanation: The Coriolis effect causes currents to deflect (to the right in the Northern Hemisphere and left in the Southern Hemisphere), it does not change their speed or move them in a straight line.

Explanation: Burning fossil fuels releases greenhouse gases, causes air pollution, and drives climate change.

Explanation: Laccoliths, Batholiths, and Dykes are all forms of intrusive (plutonic) igneous rock formations.

Explanation: The forest cover is 21.71%; the figure 24.62% represents “Forest and Tree Cover,” so technically none of the options strictly represent just “forest cover.”

Explanation: Volcanoes, faults, folds, and trenches are all direct results of plate tectonic movements.

Explanation: An ecological niche describes the functional role and position of a species within its environment, including how it gets resources and interacts with others.

Explanation: Reflected energy (albedo) is returned to space and is not absorbed, therefore it does not contribute to heating the atmosphere.
