World & Physical Geography MCQs

Notes:
All the rocks are derived from igneous rocks which are formed by the solidification of hot molten material called magma or lava. Therefore igneous rocks are also called as primary rocks or parent rocks.

Notes:
Antwerp, located in Belgium, is globally recognized as the diamond trade’s epicenter. This city, rich in art and history, houses about 84 percent of the world’s rough diamonds and 50 percent of cut diamonds. It has over 1,500 firms dealing specifically in diamonds, making it the world’s unrivaled diamond trading hub. The Antwerp province’s diamond district also houses four of the world’s 30 diamond bourses, avenues where legally certified diamonds are traded.

Notes:
Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturi, meaning treeless plain. It is present in the frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. It is a treeless biome.

Notes:
Cuba is traditionally known as the “Sugar bowl of the world” as it used to be the worlds largest sugar producer. But now brazil has taken the top spot in sugar production.

Notes:
The correct answer is the Equator. A geosynchronous orbit has an orbital period of 24 hours, matching the Earth’s rotation. For a satellite to appear stationary relative to the Earth’s surface, it must be positioned directly above the Equator at an altitude of approximately 35,786 kilometers (22,236 miles). This allows the satellite to maintain a fixed position over a specific point on the Earth’s surface, which is essential for communication and weather satellites.

Notes:
The Mekong–Ganga Cooperation was established on November 10, 2000, at Vientiane, Laos. It comprises six member countries India, Thailand, Myanmar, Cambodia, Laos and Vietnam. China is not a member.

Notes:
The moon has a significant impact on tides, due to the gravitational attraction of the moon on the Earth’s water. This effect is magnified when the moon’s gravitational attraction aligns with the gravitational pull of the sun. This produces the highest high tides and lowest low tides, known as spring tides. When the pull of the moon and the sun are perpendicular to each other, the lowest high tides and highest low tides, collectively termed neap tides, are produced. While ocean currents are primarily affected by winds and the Coriolis force, tides can have a large impact on currents near the coasts.

Notes:
The Horse Latitudes are two belts of latitudes located in between 30 degrees to 35 degrees north and south of equator. The Roaring Forties are strong westerly winds found in the Southern Hemisphere, generally between the latitudes of 40 and 50 degrees.

Notes:
High tides and low tides are caused by the moon. The moon’s gravitational pull generates something called the tidal force. The tidal force causes Earth and its water to bulge out on the side closest to the moon and the side farthest from the moon. When you’re not in one of the bulges, you experience a low tide.

Notes:
Karst topography is a result of presence of soluble rock materials beneath the surface layer which results in the wash away of the soluble material by moving water beneath the surface such that the top surface layer becomes weak.
