World & Physical Geography MCQs

Notes:
Geomorphology is the scientific study of landforms, their processes, form and sediments at the surface of the Earth. Geomorphology helps to reconstruct history of the surface of the earth through a study of its forms, the materials of which it is made up of and the processes that shape it.

Notes:
‘Ecology is defined as the scientific study of the relationship of living organisms with each other and with their environment.’ It has been derived from two Greek words, ‘oikos’, meaning home or estate and ‘logos’ meaning study. Ecology not only deals with the study of the relationship of individual organisms with their environment, but also with the study of populations, communities, ecosystems, biomes, and biosphere as a whole.

Notes:
A nova is a transient astronomical event that causes the sudden appearance of a bright, apparently “new” star, that slowly fades over time. It is caused by a nuclear explosion, caused by the accretion of hydrogen onto the surface of a white dwarf.

Notes:
Shale is an example of sedimentary rock. It is from the compaction of silt and clay-size mineral particles that we commonly call “mud.”

Notes:
Petrology is the branch of geology that studies rocks and the conditions under which they are formed. It is further divided into igneous, metamorphic, and sedimentary petrology.

Notes:
Ring of Fire is a 40,000 km horseshoe shape in Pacific Ocean basin associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements.

Notes:
Jupiter is the planet that has the fastest rotation. It has an orbital period of 12 years. It is the fifth planet from the sun.

Notes:
The rank of earth in terms of mean radius is 5. Jupiter, Saturn and Uranus are top 3 countries with mean radius.

Notes:
Kamchatka Current is a cold-water current in the northeastern Pacific Ocean. It flows southwestward from the Bering Strait, along the Siberian Pacific coast and the Kamchatka Peninsula. The current is also known as the East Kamchatka Current.  The Kamchatka Current acts like a conveyor belt, bringing cold water to the Northeastern part of Japan. The current flows at speeds of 0.2–0.3 m s-1.  The Kamchatka Current originates in the Bering Sea. A portion of the current becomes the Oyashio Current, while the remainder joins the warmer North Pacific Current.  The Kamchatka Peninsula is part of the Kamchatka Krai of the Russian Federation. The peninsula is famous for its volcanoes, with more than 300 volcanoes, including 28 to 36 active or potentially active volcanoes

Notes:
The Amazon and its tributaries flow through the countries of Peru, Bolivia, Venezuela, Colombia, Ecuador, and Brazil before emptying into the Atlantic Ocean 6, 437 kilometers from the Amazon’s headwaters high in the Andes mountains of Peru.
