General Studies Questions & Answers | Geography FAQs
Q: Hurricanes rarely form or move within 5° of equator, because [Assist. Comm, 2012]
Ans: Coriolis Effect is Weakest here
Explanation: At the equator, the Coriolis force is zero and the wind blows perpendicular to the isobars. The low pressure gets filled instead of getting intensified that is the reason, why tropical cyclones are not formed near the equator.
Q: Biome, largest recognizable assemblage of animals and plants on the Earth, is controlled mainly by [APFC 2012]
Ans: Biological Activity
Explanation: Biomes are climatically and geographically defined as similar climatic conditions on the Earth, such as communities of plants, animals and soil organisms and are often referred to as ecosystem.
Q: In which state is the ‘Guru Shikhar’ peak located? [SSC FCI 2012]
Explanation: The Guru Shikhar peak in Aravali ranges is the highest peak of Rajasthan. It is located at a distance of 15 km from Mt. Abu. The altitude of this peak is 5676 feet.
Q: The Iddukki hydroelectric plant is on river [SSC FCI 2012]
Explanation: The Iddukki hydroelectric project is the biggest hydroelectric Project in Kerala. It is built on the Periyar river, in the ravine between the Kuravan and Kurathi hills.
Q: Asteroid belt is situated between [Assist. Comm. 2012]
Ans: Mars and Jupiter
Explanation: The asteroid belt is the region of the solar system located roughly between the orbits of the planets Mars and Jupiter.
Q: Which Indian State shares international boundaries with three nations? [Assist. Comm. 2012]
Ans: Arunachal Pradesh
Explanation: Arunachal Pradesh shares boundaries with Bhutan, China and Myanmar.
Q: You placed a car in an open parking area in a summer day. After a few hours, you noticed that the heat is trapped inside the car. This phenomenon is known as [Assist. Comm 2012]
Ans: Greenhouse Effect
Explanation: The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions.
Q: The variability among living organisms from all sources including terrestrial, marine and other ecosystems and the ecological complexes of which they are part which includes diversity within species, between species of ecosystems refers to [CDS 2012]
Ans: Biological Diversity
Explanation: Biodiversity is the degree of variation of life forms within a given species, ecosystem, biome or an entire plant. Biodiversity is a measure of the health of ecosystem.
Q: The waves that help scientists to understand the internal structure of the Earth are [CDS 2012]
Ans: Secondary Waves
Explanation: Secondary waves help scientists to understand the internal structure of the Earth. This is because S-waves do not propagate through a fluid or a gas because a fluid or a gas cannot transmit a shear stress.
Q: In absorption of insolation, the most significant part is played by [CDS 2012]
Ans: Carbon Dioxide
Explanation: Earth and its atmosphere absorb 64% of the insolation. Land and water surfaces of Earth absorb 51% of this insolation. Ozone, carbon dioxide and water vapours directly absorb the remaining 13%. These gases absorb the insolation at certain wavelengths. Ozone absorbs only a small percentage of the insolation. The most important absorption occurs with C02 and water vapours, which absorb strongly over a broader wavelength bond.
Q: The most mineralised rock system of India is [CSG PSC 2012]
Ans: Dharwar System
Explanation: The rocks of the Dharwar system are mainly sedimentary in origin and occur in narrow elongated synclines resting or the gneisses found in Bellary district, Mysore and the Aravalis of Rajputana
Q: Which is the main area for producing ‘Tidal Energy’? [UP PSC 2012]
Ans: Gulf of Khambhat
Explanation: Gulf of Khambhat (Cambay) has the largest potential for tidal energy in India. The estimated potential is around 700 MW.
