Western Ghats obstruct the south-west monsoon winds coming over from _________.

  1. Black Sea

  2. Red Sea

  3. South China Sea

  4. Arabian Sea

Show answer
Correct Option: D
Explanation:

South-West monsoon has two branches, 1. Arabian sea branch, 2. Bay of Bengal branch. The moisture ladden winds of the SW monsoon follow the path of low pressure zone so as to reach ITCZ which is at ganga plains due to northward march of Sun over the tropic of cancer. While flowing towards ITCZ the Arabian Sea branch gets obstructed by the Western ghats, this gives heavy orographic rainfall on Western coast. On the other hand the bay of Bengal branch flows parallel to eastern ghats, so there is less precipitation.

Which of the following factors are climatic control factors?

  1. Latitude

  2. Altitude

  3. Distance from the sea

  4. All of these

Show answer
Correct Option: D
Explanation:

All the above are the climate control factors.
The climate of any particular place is influenced by a host of interacting factors. These include latitude, elevation, nearby water, ocean currents, topography, vegetation, and prevailing winds. The global climate system and any changes that occur within it also influence local climate.

  1. Cool weather

  2. Hot weather during summer and very cold weather during winter

  3. Moderate climate

  4. Extreme hot conditions

Show answer
Correct Option: B
Explanation:

As the distance from the sea increases, people experience extreme weather conditions, i.e., very hot during summers and very cold during winters. This condition is known as Continentality.

El-Nino is a ___________.

geography pressure belts and winds climate and seasons winds atmospheric pressure and winds

  1. Warm current

  2. Reversal of wind

  3. Broad trough of low pressure

  4. Wind of upper atmosphere

Show answer
Correct Option: A
Explanation:

El-Nino is a warm ocean current that sometimes appears off the coast of Peru in South America during the month of December. It increases the surface temperature of the sea and affects the movement of monsoon winds in the Indian Ocean and causes a drought-like situation in the Indian sub-continent. 

"Ferrel law" is also known as  _______.

  1. Jet streams

  2. Wind force

  3. Coriolis force

  4. Cyclonic force

Show answer
Correct Option: C
Explanation:
Coriolis Force: An apparent force caused by the earth’s rotation. The Coriolis force is responsible for deflecting winds towards the right in the northern hemisphere and towards the left in the southern hemisphere. This is also known as ‘Ferrel’s Law’.

A type of wind that originates from North-West India in winters is _________.

  1. Jet streams

  2. Loo

  3. North East trade winds

  4. Westerly winds

Show answer
Correct Option: A
Explanation:

Air currents which determine the arrival and departure of monsoons are known as jet streams. These curents develop in the upper layers of the atmosphere. The westerly jet stream prevails over the North Indian plains during the winter months, while the easterly jet stream steers the tropical depression over India. 

El Nino is ________.

  1. A Portuguese word

  2. A French word

  3. A Greek work

  4. A Spanish word

Show answer
Correct Option: D
Explanation:

El Nino is a Spanish word. It means "the Christ child". El Nino is complex series of climatic changes which occurs irregularly. It affects the equatorial Pacific region every few years. It is characterized by the appearance of unusually warm, nutrient-poor water off northern Peru and Ecuador. Reversal of wind patterns across the Pacific, drought in Australia, and non-seasonal heavy rain in South America are the effects of El Nino. It typically occurs in late December, around Christmas. That’s why it is known as El Nino.
