B Correct answer
Explanation

Equatorial region
Doldrums, also called equatorial calms, equatorial regions of light ocean currents and winds within the intertropical convergence zone (ITCZ), a belt of converging winds and rising air encircling Earth near the Equator.

Assertion (A) : Westerlies are stronger in the northen Hemisphere than in the southern Hemisphere
Reason (R) : The nothern Hemisphere has more land area than the southern Hemisphere.

  1. Both 'A' and 'R' are true and 'R' is the correct explanation of 'A'.

  2. Both 'A' and 'R' are true and 'R' is not the correct explanation of 'A'.

  3. 'A' is true but 'R'n is false.

  4. 'A' is false but 'R' is true
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The westerlies are the prevailing winds in the middle latitudes between $35^{\circ}$ and $65^{\circ}$ latitude blowing from the west to east. The westerlies are strong especially in the southern hemisphere where there is less land in middle latitudes to cause flow pattern to amplify. The strongest westerly winds southern hemisphere is Roaring Forties which blows between $40^{\circ}$ and $50^{\circ}$ latitudes.

Why do coastal areas experience less contrasts in temparature conditions?

  1. Due to moderating effect of the seas

  2. Due to land mass

  3. Due to heat conditions

  4. Due to rotation of the earth
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Coastal areas experience less contrasts in temperature conditions due to moderating effect of the seas.  The large water bodies helps in moderating temperature. Water has a higher heat capacity than soil and rock, so the ocean takes much longer to heat and to cool than the land.

Tropical cyclones cause rains on the _______.

  1. Malabar coast

  2. Coromandel coast

  3. Konkan coast

  4. Saurashtra coast
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Tropical cyclones causes rains on the Coromandel coast. Devastating cyclones originate in the Indian ocean especially in the Bay of  Bengal. The highest frequency of the cyclones is in the month of October and the first half of November. These cyclones are accompanied by strong winds, dense cloud, thundering and heavy rain.

An instrument which measures the force and velocity of winds is called ______________.

  1. Barometer

  2. Anemometer

  3. Thermometer

  4. Hygrometer
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

An anemometer is a device specifically designed and used for measuring wind speed and direction, making it the correct meteorological instrument. A barometer measures atmospheric pressure, a thermometer measures temperature, and a hygrometer measures humidity.

How do the pressure and temperature vary with height?

  1. Both decrease with height

  2. Both remain constant

  3. Both increase with height

  4. The pressure decreases but the temperature increases with height
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In the troposphere, which is the lowest layer of the atmosphere where weather occurs, both atmospheric pressure and temperature decrease as altitude increases.
