Solution: a)

Western Ghats are locally known by different names such as Sahyadri in Maharashtra, Nilgiri hills in Karnataka and Tamil Nadu and Anaimalai hills and Cardamom hills in Kerala. Western Ghats are comparatively higher in elevation and more continuous than the Eastern Ghats.

Eastern Ghats comprising the discontinuous and low hills are highly eroded by the rivers such as the Mahanadi, the Godavari, the Krishna, the Kaveri, etc. Some of the important ranges include the Javadi hills, the Palconda range, the Nallamala hills, the Mahendragiri hills, etc.

The Eastern and the Western Ghats meet each other at the Nilgiri hills.

Winter Solstice:

• Winter Solstice (usually 21st or 22nd December) is the shortest day of the year in the Northern Hemisphere. In the Southern Hemisphere, conversely it is Summer Solstice, the year’s longest day.
• The winter solstice happens every year when the Sun reaches its most southerly declination of -23.5 degrees.
• It is when the North Pole is tilted farthest away from the Sun, delivering the fewest hours of sunlight of the year.
• The Sun is directly overhead of the Tropic of Capricorn in the Southern Hemisphere.

Solution: d)

EI-Nino is merely an extension of the warm equatorial current which gets replaced temporarily by cold Peruvian current or Humboldt Current. This current increases the temperature of water on the Peruvian coast by 10°C.This results in:

• the distortion of equatorial atmospheric circulation;
• irregularities in the evaporation of sea water;
• reduction in the amount of planktons which further reduces the number of fish in the sea.

Solution: c)

The Ten Degree Channel is a channel that separates the Andaman Islands and Nicobar Islands from each other in the Bay of Bengal.

Solution: b)

When the rivers originate from a hill and flow in all directions, the drainage pattern is known as ‘radial’. The rivers originating from the Amarkantak range present a good example of it. 

An area drained by a river and its tributaries is called a drainage basin. The boundary line separating one drainage basin from the other is known as the watershed.
