World & Physical Geography MCQs

Notes:
The El Cajon Dam, officially known as Central Hidroelectrica Francisco Morazan, is a hydroelectric power plant located in Western Honduras. The dam impounds the Comayagua River, which derives its large volume from two large tributaries, the Humuya River and the Sulaco River. El Cajon is a double arch dam, which uses parabolic geometry in horizontal and vertical axes to spread the weight of the impounded water to canyon walls which act as buttresses. Overall, the dam is the fifth-highest dam in the Americas and the 16th highest in the world, as well as the highest arch dam in the western hemisphere, and the sixth-highest worldwide.

Notes:
Iceland’s major power source is the “Nesjavellir Geothermal Power Station”. The Nesjavellir Geothermal Power Station (NGPS) is the second-largest geothermal power station in Iceland. The facility is located 177 m above sea level in the southwestern part of the country, near Thingvellir and the Hengill Volcano.

Notes:
The Western Tien Shan is situated in the Jalal-Abad province of Kyrgyzstan. It was designated as world heritage site in 2015.

Notes:
The longest river of United Mexican States is river Rio Grande. The river begins its journey from Colorado in USA and flows into Gulf of Mexico. Its total length is about 3051 km.

Notes:
Montenegro is a Balkan country located in the Adriatic sea in the southeast Europe. It shares its borders with Albania, Croatia, Serbia, Kosovo and Bosnia and Herzegovina.

Notes:
The solar mass is used to indicate the masses of other stars, as well as clusters, nebulae and galaxies. It is equal to the mass of the Sun, about two nonillion (two quintillion in the long scale) kilograms. It is equal to approximately 1.99 × 1030 kilograms.

Notes:
Karst topography, a landscape formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum, characterized by underground drainage systems with sinkholes and caves.A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer. They are common where the rock below the land surface is limestone or other carbonate rock, that can be dissolved naturally by circulating ground water.

Notes:
An updraught or downdraught is the vertical movement of air as a weather related phenomenon. Better known as air current, they can be caused by differences in temperature, pressure, or impurity concentration. Temperature differences can cause air currents because warmer air is less dense than cooler air, causing the warmer air to appear “lighter.” Rising air is associated with turbulence as it creates a low pressure on the surface.

Notes:
The Suez Canal is an artificial waterway in Egypt extending from Port Said to Suez and connecting the Mediterranean Sea with the Red Sea. It is one of the world’s most important waterways. The canal separates the African continent from Asia, and it provides the shortest maritime route between Europe and the lands lying around the Indian and western Pacific oceans. It is one of the world’s most heavily used shipping lanes. The canal extends 101 miles (163 kilometres) between Port Said in the north and Suez in the south, with dredged approach channels north of Port Said into the Mediterranean, and south of Suez.

Notes:
The Philippines faces an average of 20 typhoons annually, attributable to its position in the northwest Pacific Ocean, which is a breeding ground for tropical cyclones, making it one of the regions most affected by typhoons globally.
