World & Physical Geography MCQs

Notes:
The largest lake of the Republic of Lithuania is the lake Druksiai. It is situated in the northeastern part of the country. It is made by the river Nemunas and covers an area about 4.4 square kilometers.

Notes:
The longest river of Mongolia is Orkhon river. It rises in the Khangai mountains in the Tsenkher sum of Arkhangai amaig at the Kherkhan mountain. Its length is about 1124 km.

Notes:
Cliffs, caves, arches, stacks are some of the landforms produced by wave erosion. Caves form where rock runs in bands horizontal to the direction of wave attack. There is a band of resistant rock closest to the sea and a band of less resistant rock inland. The waves seek out faults in the hard rock and erodes using the processes of abrasion/corrasion and hydraulic action through to the soft rock behind.

Notes:
Winter solstice is an astronomical phenomenon marking the shortest day and the longest night of the year. In the Northern Hemisphere this is the 21st December solstice and in the Southern Hemisphere this is the 21st June solstice. Solstices are opposite on either side of the equator, so the winter solstice in the northern hemisphere is the summer solstice in the southern hemisphere and vice versa.

Notes:
A river delta is a landform created by deposition of sediment that is carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot carry away the supplied sediment.

Notes:
The climatic zones are classified on the basis of maximum and minimum temperatures and the temperature range as well as the total and seasonal distribution of precipitation. Based on these parameters, the most commonly used classification scheme was originally developed by Wladimir Koppen.

Notes:

• Chinook: a warm, westerly wind of Canada and USA
• Foehn: a warm, dry, gusty wind of the Alps
• Sirocco: blows by the local name of Khamsin in Egypt

Notes:
Insolation is a measure of solar radiation energy received on a given surface area in a given time. It mainly depends on two factors: (a) the angle at which the Sun’s rays strike the Earth, and (b) the length of time of exposure to the rays. Both of these factors are controlled by the latitude of the location and time of the year.

Notes:
Dasht-e Kavir is great salt desert of north-central Iran. Located in a basin southeast of the Elburz Mountains, it is approximately390 km wide. The desert is distinguished by its salt crust, caused by the almost rainless climate and intense surface evaporation, lying over treacherous quick sand like salt marshes that are almost uninhabited.

Notes:
Bomb cyclones, or weather bombs, are rapidly deepening low-pressure systems, primarily occurring in winter across both hemispheres. They are mainly maritime phenomena but can also happen in summer on land. Bombogenesis, the process behind their formation, is most common in four hotspots: Northwest Pacific, North Atlantic, Southwest Pacific, and South Atlantic. In the Northern Hemisphere, it frequently occurs north of the Gulf Stream and Kuroshio Current, while in the Southern Hemisphere, it is prevalent above the East Australian Current.
