The Sargasso Sea is a part of the
Detailed Explanation:
The Sargasso Sea is a unique region in the North Atlantic Ocean, bounded by four major currents: the Gulf Stream, North Atlantic Current, Canary Current, and North Atlantic Equatorial Current. These currents form an ocean gyre that traps floating Sargassum seaweed, giving the sea its distinctive name and golden appearance.
Unlike conventional seas, it has no land boundaries and is defined entirely by circulating ocean currents. It lies entirely within the North Atlantic, ruling out the Arctic, South Atlantic, and Indian Oceans.
Therefore, the Sargasso Sea is located in the North Atlantic Ocean, making Option 2 the correct answer.
Which is the chief heavenly body of solar system?
Detailed Explanation:
The Sun is the central and most massive body of the solar system, containing over 99% of its total mass. All planets, asteroids, comets, and other celestial objects revolve around it due to its immense gravitational pull.
Jupiter and Saturn are the largest planets but remain much smaller than the Sun. Earth is our home planet but neither central nor dominant in mass.
Therefore, the Sun is the chief heavenly body, making Option 3 the correct answer.
Which elements are abundant in the formation of interior layer of the earth Nife?
Detailed Explanation:
The Earth's core, called Nife, is composed primarily of nickel (Ni) and iron/ferrum (Fe), making it the densest layer (density 9.5–14.5 g/cm³).
The mantle is made of silicon and magnesium (Sima), while the crust consists of silicon and aluminium (Sial)—neither forms the core.
Therefore, nickel and ferrum are abundant in Nife, making Option 3 the correct answer.

Who among the following postulated the concept of geographical cycle of erosion?
Detailed Explanation:
William Morris Davis (W. M. Davis) postulated the geographical cycle of erosion in 1899, also known as the cycle of erosion. This model describes landform evolution through sequential stages: youth, maturity, and old age.
S. W. Wooldridge contributed to geomorphology but did not develop this cycle; Kober worked on mountain building theories; A. Holmes is known for geochronology and mantle convection—none proposed the erosion cycle.
Therefore, W. M. Davis is the correct answer, making Option 1 correct.
In which hemisphere, roaring forties, furious fifties and shrieking sixties blowing?
Detailed Explanation:
The Roaring Forties (40°–50°S), Furious Fifties (50°–60°S), and Shrieking Sixties (60°–70°S) are powerful westerly winds in the Southern Hemisphere, blowing unobstructed across vast oceanic expanses with minimal landmass interference.
In the Northern Hemisphere, westerlies are weaker and irregular due to large continental landmasses disrupting wind flow, hence these distinct names apply exclusively to the south.
Therefore, these winds blow in the Southern Hemisphere, making Option 1 the correct answer.
