WORLD GEOGRAPHY 2

Hydrosphere:

Focus:

A general idea about configuration of Ocean Floor – Continental Shelf, Slope, Rise, Abyssal Plan, Trenches.
Straits and Isthmuses- differences between them; Locate the famous Straits and Isthmuses on Atlas. Example: Strait of Gibraltar, Isthmus of Panama.
Fresh water found on the Earth’s surface. Ice caps, Glaciers and ground Water, Lakes, atmosphere
Ocean Currents (More Emphasis should be given)
Factors influencing the Movement of the Ocean Currents- Planetary Winds, Temperatures, Salinity, Earth’s Rotation, Land mass
Types- Warm and Cold Currents
What are Warm and Cold Currents, why are they called so?
Characteristics of the Currents
Identify the Warm and Cold Currents and their direction of flow in Northern and Southern Hemisphere. Example: Peru Cold current, in the Southern Hemisphere flows in the Anti-Clockwise direction
How do these currents influence the climate and vegetation across the world?
Benefits of these currents, Example: Confluence of Warm and Cold currents is region rich in fisheries. Disadvantages – Example: They make navigation difficult for the sailors

Example (2013 Prelims Questions Paper):

On the planet earth, most of the freshwater exists as ice caps and glaciers. Out of the remaining freshwater, the largest proportion

(a) is found in atmosphere as moisture and clouds

(b) is found in freshwater lakes and rivers

(d) exists as soil moisture

Solution (c)

The most important fishing grounds of the world are found in the regions where:(2013)

(a) warm and cold atmospheric currents meet

(b) rivers drain out large amounts of fresh water into the sea

(d) continental shelf is undulating

Solution (c)

Different Climatic types

Focus:

Have a basic idea about major Climatic Types – Tropical, Desert, Mediterranean, Taiga, Arctic (or Polar type)
Distribution or regions found (a general awareness)
Climate – temperature, rainfall (not exact numbers, just the range is enough)
Natural Vegetation, Forests:
Tropical (Forests, Grasslands, Deserts)
Mediterranean
Temperate ( Forests, Grasslands, Deserts)
Polar Tundra
Importance of the region and other activities carried out
Example: The Arctic or Polar Climate- they are found mainly in the north of the Arctic circle in the Northern Hemisphere. Temperature- ranges from 10 C to -37 C, Winters are long and very severe whereas summers are cool and brief. Precipitation is in the form of snow. Tundra Vegetation. It has gained importance due to discovery of minerals.
How do all these phenomenon influence Indian climate and vegetation
For better understanding refer these pages in the ‘The Orient BlackSwan School Atlas’
Atlas: Page No. 84 ‘Natural Vegetation’ and Page No. 85 ‘Climatic Regions’

Note: These pointers might be boring or difficult to remember. But using an Atlas, while studying these aspects of Geography, will make your preparation process enjoyable. You don’t believe us. Then, pick up an Atlas and experience it yourself J

Note: Though Topics like Ecosystems, Biomes, Biogeochemical cycles (Carbon, Nitrogen, Oxygen), Biodiversity and Conservation come under Geography they are covered under Environment Section

Example (2011 Prelims Questions Paper):

What could be the main reason/reasons for the formation of African and Eurasian desert belt?

1. It is located in the sub-tropical high pressure cells.

2. It is under the influence of warm ocean currents.

Which of the statements given above is/are correct in this context?

(a.) 1 only

(b.) 2 only

(c.) Both 1 and 2

(d.) Neither 1 nor 2

Solution (a)

Example (2012 Prelims Questions Paper):

Which one of the following is the characteristic climate of the Tropical Savannah Region? (2012)

(a) Rainfall throughout the year

(b) Rainfall in winter only

(d) A definite dry and wet season

Solution (d)

Example (2013 Prelims Questions Paper):

“Climate is extreme, rainfall is scanty and the people used to be nomadic herders.” The above statement best describes which of the following regions?

(a) African Savannah

(b) Central Asian Steppe

(d) Siberian Tundra

Solution (b)

Last but not the Least – Map-based questions have been frequently asked in UPSC prelims

Check out a few of them (from 2014 Question paper alone, 6 Questions had come). That is why, in the beginning itself, we had advised you to always keep an Atlas by your side while preparing for Geography

Though UPSC keeps changing its pattern of questions every year, atleast one can accept minimum 2 questions from Maps alone.

So, the next question would be- how to study/read Maps?

Studying maps alone is not advised and it is impossibleJ . While studying Geography or when you are reading Daily Newspaper, supplement it with an Atlas. When you read about a ‘place’ that is in news, look out for it in the Atlas; and also be aware of the nearby places.

Map-based Questions

Speechless as usual , going though your site in past 2 days ! No words will do justice to what u have accomplished here . The student community is going to be speechless at the awesomeness of this site and the coachingwallahs are going to be dumbfounded ( I suspect most of them are going to refer to your site to formulate their own strategies on how to teach 😉 ) . You just made the preparation of IAS a truly level playing field , no matter where we are , what our economic status , job status , etc etc … everyone can play the game equally well now . All we need to bring with ourselves now is a lot of enthusiasm and will to work (and internet access 🙂 ) . You will take care of the rest !!
(PS : Although only 2 months remain for PT , I am planning to dedicate the whole day today to reformulate my strategy and plan around your site . I know it will be worth it . Totally . Period . )
