Insights Revision Plan for Prelims 2016: Test – 14
18 June 2016
Questions Based on Day – 14 Syllabus
NOTE: Eventually we will cover all left out chapters/books in coming days.
Please Read before you Proceed to Take Today’s Test:
Hope you have completed yesterday’s targets and now ready to give this test. Please note that you should not worry about scores in these tests. Questions are mainly intended not to test your knowledge, but show which areas to focus when you study and how to study them. It’s more a learning process than testing process.
If you have any doubt, please discuss them in comment section. We are not giving explanations for CSAT questions (Yes, we have included them too!), please someone from you explain them in comment box. As of now we are posting previous year CSAT questions.
Note: As sources are numerous, we can not cover all of them within 20-25 questions. Even then, please try to complete 100% of targets. You will never know from which topic question might come!

Question 2 of 15
2. Question
2 pointsWhen a tsunami or storms approach, which of the following features first offer the buffer or defence against them and absorb most of their destructive force?
Correct
Solution: a)
NCERT Class XI, Fundamentals of Physical Geography, Page – 71
The coastal off-shore bars offer the first buffer or defence against storm or tsunami by absorbing most of their destructive force. Then come the barriers, beaches, beach dunes and mangroves, if any, to absorb the destructive force of storm and tsunami waves. So, if we do anything which disturbs the ‘sediment budget’ and the mangroves along the coast, these coastal forms will get eroded away leaving human habitations to bear first strike of storm and tsunami waves

Question 3 of 15
3. Question
2 pointsIn which one of the following regions the chemical weathering process is more dominant than the mechanical process?
Correct
Solution: c)
NCERT Class XI, Fundamentals of Physical Geography, Page – 73
Chemical Weathering Processes
A group of weathering processes viz; solution, carbonation, hydration, oxidation and reduction act on the rocks to decompose, dissolve or reduce them to a fine clastic state through chemical reactions by oxygen, surface and/or soil water and other acids. Water and air (oxygen and carbon dioxide) along with heat must be present to speed up all chemical reactions. Over and above the carbon dioxide present in the air, decomposition of plants and animals increases the quantity of carbon dioxide underground.
Above conditions are ample in limestone regions.

Question 6 of 15
6. Question
2 pointsThe Isotherms are lines joining places having equal temperature. On the North Atlantic Ocean and surrounding land regions, in January, the isotherms deviate to the north over the ocean and to the south over the continent. Why?
Correct
Solution: b)
NCERT Class XI, Fundamentals of Physical Geography, Page – 83
In the northern hemisphere the land surface area is much larger than in the southern hemisphere. Hence, the effects of land mass and the ocean currents are well pronounced. In January the isotherms deviate to the north over the ocean and to the south over the continent. This can be seen on the North Atlantic Ocean. The presence of warm ocean currents, Gulf Stream and North Atlantic drift, make the Northern Atlantic Ocean warmer and the isotherms bend towards the north. Over the land the temperature decreases sharply and the isotherms bend towards south in Europe.

Question 7 of 15
7. Question
2 pointsDuring summer, in which one of the following cities, are the days the longest?
Correct
Solution: c)
NCERT Class XI, Fundamentals of Physical Geography, Page – 85
The factor that determines the amount of insolation received is the angle of inclination of the sun rays. This depends on the latitude of a place. The higher the latitude the less is the angle they make with the surface of the earth resulting in slant sun rays (which means longer days).
Compared to other cities, Chandigarh is located in higher latitude, hence days are longer there.

Question 12 of 15
12. Question
2 pointsThe energy that intensifies the tropical cyclone mainly comes from
Correct
Solution: a)
NCERT Class XI, Fundamentals of Physical Geography, Page – 95
The energy that intensifies the storm, comes from the condensation process in the towering cumulonimbus clouds, surrounding the centre of the storm. With continuous supply of moisture from the sea, the storm is further strengthened. On reaching the land the moisture supply is cut off and the storm dissipates.

Question 13 of 15
13. Question
2 pointsWhich one of the following is the source region for the formation of air masses?
Correct
Solution: b)
NCERT Class XI, Fundamentals of Physical Geography, Page – 96
A source region must have certain temperature and humidity properties that can remain fixed for a substantial length of time to affect air masses above it.
Air mass source regions occur only in the high or low latitudes; middle latitudes are too variable.
Siberian plains plain fulfills above criteria, whereas other regions do not.
