World & Physical Geography MCQs

Notes:
Systematic approach of geography is divided into four main branches.
(i) Physical geography,
(ii) Biogeography, including environmental geography,
(iii) Human geography,
(iv) Geographical methods and techniques
Regional approach geography is divided into
(i) Regional studies
(ii) Regional analysis
(iii) Regional development
(iv) Regional planning including areas and community planning

Notes:
The sun accounts for approximately 99.86% of the total mass of the solar system. The remaining 0.14% is made up of the planets and their moons, as well as asteroids, comets, and other small bodies. The sun is an enormous, luminous ball of gas that is the dominant gravitational force in the solar system. It is made up of mostly hydrogen and helium, and is so massive that the gravitational pull of its own mass keeps it from collapsing under its own weight. The sun is the primary source of light and heat for the solar system and plays a vital role in the formation and evolution of the planets and other bodies that orbit around it.

Notes:
The precession of the Earth’s axis has a number of observable effects. First, the positions of the south and north celestial poles appear to move in circles against the space-fixed backdrop of stars, completing one circuit in 25,772 Julian years (2000 rate). Thus, while today the star Polaris lies approximately at the north celestial pole, this will change over time, and other stars will become the “north star”

Notes:
A barchan is indeed a type of dune. Characterized by its distinctive crescent shape and known to exist in arid desert environments, it faces the wind in a convex orientation. Barchans are not static; rather, they are able to shift and transform due to the predominant wind direction. This wind action contributes to their unique form and continual movement, enlightening us about the dynamic nature of desert topography.

Notes:
Zodiac constellations are the 12 constellations that lie along the plane of the ecliptic, which is defined by the circular path of the Sun across the sky, as seen from Earth. The 12 constellations in the zodiac family can all be seen along the ecliptic. They are: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpius, Sagittarius, Capricornus, Aquarius and Pisces.

Notes:
Arakan yoma is the extension of the himalayas located in Myanmar. The Arakan Mountains are also known as the Rakhine Mountains. These are a mountain range in western Myanmar, between the coast of Rakhine State and the Central Myanmar Basin, in which the Irrawaddy River flows.

Notes:
Benguela Current, oceanic current that is a branch of the West Wind Drift of the Southern Hemisphere. It flows northward in the South Atlantic Ocean along the west coast of southern Africa nearly to the Equator before merging with the westward-flowing Atlantic South Equatorial Current.
Guinea Current, surface oceanic current of the Atlantic Ocean, the eastward continuation of the Atlantic Equatorial Countercurrent, off the western coast of Africa near the Gulf of Guinea. The warm, highly saline Guinea Current reaches a depth of less than 660 feet (200 m).

Notes:
The Yangtze River is the longest river in Asia. It is third longest river in the world. It flows entirely within China. It is also the longest river in the world to flow within one country.

Notes:
Interferometer is used in astronomy to measure the diameters of the stars. It was invented in the late 19th century by Albert Michelson

Notes:
BepiColombo is a joint mission of European Space Agency (ESA) and Japan Aerospace Exploration Agency (JAXA) to the planet Mercury.
