World & Physical Geography MCQs

Notes:
Sierra del Merendon is a mountain range extending on the eastern border of Guatemala and Honduras. Its south-western border is marked by the Lempa River valley, its northern border by the Motagua River valley. The mountain range has several different biomes and habitats, including cloud forests.

Notes:
The Pacific Ocean forms the coastline of Honduras through the Gulf of Fonseca. Honduras is a country in Central America. The Republic of Honduras is bordered to the west by Guatemala, to the southwest by El Salvador, to the southeast by Nicaragua, to the south by the Pacific Ocean at the Gulf of Fonseca, and to the north by the Gulf of Honduras, a large inlet of the Caribbean Sea.

Notes:
There are total of 15 rivers in Lebanese Republic. All of the 15 rivers have their source of origin in the mountains of Lebanon itself.

Notes:
The Republic of Lithuania is situated in the Baltic region of eastern Europe. The total land under forests in Lithuania is about 21306 sq. km which is about 34% of the total land of the country.

Notes:
The longest river of the country is river Niger which is about 4,180 km long out of which about 1,700 km flows through Mali. It is the third-longest river of Africa.

Notes:
The Himalaya are among the youngest mountain ranges on the planet and consist mostly of uplifted sedimentary and metamorphic rock. They are Fold Mountains which were formed due to a continental collision or orogeny along the convergent boundary between the Indo-Australian Plate and the Eurasian Plate.

Notes:
The average temperature on Earth is about 61o F (16o C). But temperatures vary greatly around the world depending on the time of year, ocean and wind currents and weather conditions. Summers tend to be warmer and winters colder. Also, temperatures tend to be higher near the equator and lower near the poles.

Notes:
The Earth has three layers : Outer layer : Continents [SiAl – Silica + Aluminum]; the main mineral constituents of the continental mass are sial. Mantle and oceanic crust : SiMa; oceanic crust mainly consist of sima. Typically, when the sima comes to the surface it is basalt, so sometimes this layer is called the ‘basalt layer’ of the crust. The sima layer is also called the ‘basal crust’ or ‘basal layer’ because it is the lowest layer of the crust. Because the ocean floors are mainly sima, it is also sometimes called the ‘oceanic crust’ Inner layer : Core [NiFe – nickel + ferrous]. Outer core is liquid and inner core is solid.

Notes:
These jet streams are located approximately over 27°-30° north latitude, therefore, they are known as subtropical westerly jet streams. Over India, these jet streams blow south of the Himalayas, all through the year except in summer. The western cyclonic disturbances experienced in the north and northwestern parts of the country are brought in by westerly jet streams.

Notes:
The slythmic side and fall of ocean water twice in a day is called a Tide. Tide-generating forces (TGF) are a result of the gravitational attraction between the earth, the sun, and the moon and the centrifugal force due to the relative motions of the moon around the earth, and the earth around the sun. While these forces exactly balance on average, the local mismatch at the earth’s surface creates a horizontal force directed towards the surface points closest and farthest from the moon.
