World & Physical Geography MCQs

Notes:
1 hour is equal to 15 degress. 360 degrees is equal to 24 hours and when we divide 360 by 24 we get each hour equal to 15 degree.

Notes:
Most of the coral reefs are found in Pacific Ocean. Pacific ocean has twice as many coral species as in Atlantic Ocean reefs. About 75% of the total coral reef in United States, is located in the Pacific Ocean.

Notes:
The correct answer is Western Disturbances. These are weather systems originating in the Mediterranean region that bring moisture-laden winds to the Indian subcontinent, particularly affecting northern India, including Bihar, Uttar Pradesh, and West Bengal. They typically occur during winter and early spring, contributing to rainfall and influencing the agricultural patterns in these regions. Eastern Disturbances are less common and do not importantly impact these areas.

Notes:
Pyroclastics are sedimentary clastic rocks. They compose mainly volcanic material. Where the volcanic material has been transported and reworked through mechanical action, such as by wind or water, these rocks are termed volcaniclastic.

Notes:
Maldives is known as “Dhivehi Jumhuriya” in its local language. Jumhuriya means republic.

Notes:
The term “cosmic rays” was coined by the Austrian physicist Victor Francis Hess in 1912. Hess was awarded the Nobel Prize in Physics in 1936 for his discovery of cosmic rays.

Cosmic rays are high-energy particles that travel through space and reach the Earth’s atmosphere. They are believed to be made up of protons, electrons, and atomic nuclei, and they can have energies that are millions or billions of times greater than those of particles produced by particle accelerators on Earth.

Hess discovered cosmic rays while conducting experiments in which he flew high-altitude balloon flights to measure the radiation levels at different altitudes. He found that the radiation levels increased with altitude, leading him to conclude that the radiation was coming from outer space and not from the Earth’s surface. He named these high-energy particles “cosmic rays” because they seemed to be coming from the cosmos.

Notes:
The Acasta Gneiss is located in the Northwest Territories of Canada. The rock is exposed on an island about 300 kilometers north of Yellowknife. The Acasta Gneiss is one of the oldest known intact crustal fragments on Earth. The rock was metamorphosed between 3.58 and 4.031 billion years ago.  The Acasta Gneiss was first described in 1989. It was discovered during fieldwork in 1983 by Geological Survey of Canada geologist Janet King.  Gneiss is a type of rock that has been metamorphosed by intense heat and pressure at depth in Earth’s crust. The original, unmetamorphosed rock was a granite, an intrusive igneous rock.

Notes:
Shakespeare beach is located at the foot of the Shakespeare Cliff along the Dover Harbour, situated in Dover, Kent, south-east England.

Notes:
Olympus Mons is a very large shield volcano on the planet Mars. The volcano has a height of over 21 km. Olympus Mons is about two and a half times Mount Everest’s height above sea level.

Notes:
The “harvest moon” is a traditional term for the full moon occurring during autumn, in the northern hemisphere usually on September 22 or 23.
