World & Physical Geography MCQs

Notes:
The Caspian Sea lies to the north of Iran. Iran is a country in Western Asia. It is bordered to the northwest by Armenia and Azerbaijan, to the north by the Caspian Sea, to the northeast by Turkmenistan, to the east by Afghanistan, to the southeast by Pakistan, to the south by the Persian Gulf and the Gulf of Oman, and to the west by Turkey and Iraq. It is the second-largest country in the Middle East, and its capital and largest city is Tehran.

Notes:
The Republic of Ireland is situated in the North Atlantic Ocean. United Kingdom lies to its immediate east.

Notes:
The largest lake in Kenya is Lake Turkana. It covers an area about 6405 sq. km. It is the world’s largest desert lake.

Notes:
Lithuania is a country located in the Baltic region of European continent. It shares its smallest border with the state of Poland which is about 71 km long.

Notes:
A solar eclipse occurs when the moon crosses the path between the sun and the earth. The darkest shadow (where the sun is completely covered) is called the umbra. The umbra is narrow at the distance of the Earth, and a total eclipse is observable only within the narrow strip of land or sea over which the umbra passes. The partial shadow is called the penumbra.

Notes:
The stratosphere defines a layer in which temperatures rises with increasing altitude. At the top of the stratosphere the thin air may attain temperatures close to 0oC. This rise in temperature is caused by the absorption of ultraviolet (UV) radiation from the Sun by the ozone layer. Such a temperature profile creates very stable atmospheric conditions. Consequently, the stratosphere is almost completely free of clouds or other forms of weather.

Notes:
In oceanography, terrigenous sediments are those derived from the erosion of rocks on land; that is, they are derived from terrestrial (as opposed to marine) environments. Consisting of sand, mud, and silt carried to sea by rivers, they are mainly deposited on the continental shelfand slopes. Terrigenous sediments that reach the continental shelf are often stored in submarine canyons on the continental slope. Turbidity currents carry them down into the deep sea.

Notes:
Most of the credit for making drip irrigation what it is today goes to Israel and South Africa where it is most efficiently used. As with most water-scarce countries, Israel has seen first hand how efficient irrigation methods and strategic water reuse can help ensure sustainable, reliable agricultural production.

Notes:
A land cyclone is a rare weather system with a low-pressure center that forms over land, occurring only 14 times since 1891. A mesocyclone is an air vortex within a convective storm, with a diameter of 3.2 to 9.7 km. A subtropical cyclone combines features of tropical and extratropical cyclones and forms at lower sea surface temperatures than tropical cyclones. Wave cyclones, or extratropical cyclones, are low-pressure areas that develop in middle and high latitudes, primarily between 30° and 60° latitude.

Notes:
The Puerto Princesa Subterranean River, located in the Philippines, is renowned as the world’s longest navigable underground river. Stretching over 8.2 kilometers within a UNESCO World Heritage Site, it is celebrated for its breathtaking limestone karst landscapes, extensive cave systems, and diverse ecosystem.
