World & Physical Geography MCQs

Notes:
Geography is studied majorly by using two approaches
1. Systematic approach
2. Regional approach
Systematic geography approach was introduced by German Geographer Alexander Von Humboldt where as regional geography approach was introduced by another German geographer Karl Ritter
• Any phenomenon of geography in systematic approach is studied world over as a whole, and then the identification of typologies or spatial patterns is done.

• In the regional approach, the world is divided into regions at different hierarchical levels and then all the geographical phenomena in a particular region are studied

Notes:
Sometimes Venus appears in the eastern sky before sunrise. Sometimes it appears in the western sky just after sunset. Therefore it is often called a morning or an evening star, although it is not a star.

Notes:
Santa Ana, Brickfielder, Sirocco & Khamsin are examples of hot Winds. Hot Local winds are occur because of the downslope compressional heating also known as adiabatic heating. Examples of the Hot Local Winds include Chinook, Harmattan, Foehn, Sirocco, Norwester, Brickfielder, Khamsin, Santa Ana, Loo, etc.

Notes:
Umbra is shadow is a dark area which is formed when light from a light source is blocked by an opaque object. It occupies all of the three-dimensional volume behind an object with light in front of it. The cross section of a shadow is a two-dimensional silhouette, or a reverse projection of the object blocking the light.

Notes:
Pluto has been given a new name to reflect its new status as a dwarf planet. The 9th planet was assigned the asteroid number 134340 by the Minor Planet Center (MPC), the official organization responsible for collecting data about asteroids and comets in our solar system.

Notes:
The question is related to the centrifugal forces, which represent the effects of inertia that arise in connection with rotation and which are experienced as an outward force away from the center of rotation. The impact of this force is maximum at Equator and minimum at Pole.

Notes:
The salinity of Red Sea is greater than the world average, approximately 4 percent. It has been also cited as most saline open sea due to high rate of evaporation and very little precipitation, Lack of significant rivers or streams draining into the sea and limited connection with the Indian Ocean, which has lower water salinity.

Notes:
Gulfs with narrow fronts and wider rears would expect highest tides among all the four configurations. One example is Gulf of Mexico. The Gulf of Mexico has high tides because all the water must get in and out of the Gulf through the narrow Florida Straits.

Notes:
Sandstone is a clastic sedimentary rock composed mainly of sand-sized mineral particles or rock fragments. Most sandstone is composed of quartz or feldspar because they are the most resistant minerals to weathering processes at the Earth’s surface, as seen in Bowen’s reaction series.

Notes:
An oil refinery or petroleum refinery is an industrial process plant where crude oil is transformed and refined into more useful products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene, liquefied petroleum gas, jet fuel and fuel oils. It is indicated by the potion marked with ‘B’.
