World & Physical Geography MCQs

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:
Mont blanc is located between Italy and France. Alps is mountain range in Europe.

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:
The Gulf Stream is a warm current. It along with the northern extension the North Atlantic Drift and swift Atlantic Ocean current that originates in the Gulf of Mexico and stretches to the tip of Florida and eastern coastlines of the United States and Newfoundland.

Notes:
The color of a star indicates Temperature. The color of fire indicates the temperature so a star’s color is proportional to Temperature.

Notes:
The hottest temperature ever recorded on Earth was in El Azizia, Libya on September 13, 1922. The temperature reached a staggering 57.8 degrees Celsius (136 degrees Fahrenheit). This record temperature was later contested by a new world record temperature of 56.7°C (134°F) which was recorded in Furnace Creek Ranch, Death Valley, USA. However, the Death Valley record has faced controversies and hence remains debatable.

Notes:
The correct reason for sprinkling salt on icy roads is that “the salt lowers the freezing point of water.” This process is known as freezing point depression. When salt (sodium chloride) is added to ice, it disrupts the formation of ice crystals, causing the ice to melt at lower temperatures. This is why salt is commonly used in winter road maintenance. it helps to keep roads safer by preventing ice formation. In fact, salt can lower the freezing point of water to about -9.5°C (15°F) when used in sufficient quantities.

Notes:
The area of the United States known as the South Plains is the largest contiguous cotton-growing region in the world

Notes:
Gulf of Saint Lawrence is the largest estuary in the world. It is the outlet of the North American Great Lakes via the Saint Lawrence river into the Atlantic Ocean, where freshwater and salt water mix together.

Notes:
Thwaites Glacier is also known as the Doomsday Glacier. It is a fast Antarctic Glacier and flows into the Pine Island Bay, which is a part of the Amundsen Sea.
