[B] A style of Dune
[C] A desert landform called Erg
[D] An expansive sandy terrain known as Sand sea
Show Answer
Correct Answer: B [A style of Dune]
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.
3. The part of Earth’s lithosphere that surfaces in the ocean basins is called ?
[A] Ocean floor
[B] Ocean crust
[C] Continental slope
[D] None of the above
Show Answer
Correct Answer: B [Ocean crust]
Notes:
Ocean crust is the thinner layer of the Earth’s lithosphere. It forms. This is the layer of igneous, sedimentary, and metamorphic rocks which form the continents and the shallow sea beds close to the shores.
4. Standard time zones can be defined by geometrically subdividing the Earth’s spheroid into how many parts?
[A] 12
[B] 24
[C] 36
[D] 48
Show Answer
Correct Answer: B [24]
Notes:
Standard time zones are typically defined by subdividing the Earth’s spheroid into 24 parts, with each part corresponding to a time zone that is typically 15 degrees wide. This means that the Earth is divided into 24 time zones, each separated by an hour, starting at the Prime Meridian, which is 0 degrees longitude, and extending eastward and westward around the globe.
5. Which among the following is the windiest place on earth?
[A] North Pole
[B] Indian Ocean
[C] Antarctica
[D] Gobi Desert
Show Answer
Correct Answer: C [Antarctica]
Notes:
Antarctica is considered to be the windiest place on Earth. The winds in Antarctica are often strong and persistent, with average wind speeds of around 6 meters per second and gusts reaching up to 200 kilometers per hour. These strong winds are caused by the unique weather patterns in the region, which are influenced by the cold temperatures and the presence of the Antarctic ice sheet.
6. Which of the following winds lets the Central Europe enjoy a warmer climate?
[A] Chinook
[B] Foehn
[C] Zonda
[D] Bergwind
Show Answer
Correct Answer: B [Foehn]
Notes:
Foehn is the winds lets the Central Europe enjoy a warmer climate. Chinook winds, flow in the interior West of North America.
7. A difference between 2 longitudes at equator is nearby equivalent to how many Km?
[A] 101 km
[B] 111 km
[C] 91 km
[D] 121 km
Show Answer
Correct Answer: B [111 km]
Notes:
At the equator, the distance between two longitudes is, 40075 km divided by 360 and that is, 111.32 km, indeed. That is, of course, if you measure the distance between two integer number longitudes.
8. Which of the following is an ore of iron?
[A] Epsom
[B] Siderite
[C] Galena
[D] Dolomite
Show Answer
Correct Answer: B [Siderite]
Notes:
Siderite is a mineral composed of iron(II) carbonate (FeCO3). It takes its name from the Greek word ‘sideros’, “iron”. It is a valuable iron mineral, since it is 48% iron and contains no sulfur or phosphorus.

[B] A layer
[C] E layer
[D] C layer
Show Answer
