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

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.

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.

C Correct answer
Explanation
  • The barometer is used for measuring atmospheric pressure, hence option C is correct.
  • Thermometer, is used to measure the temperature of human body.
  • Anemometer is used to measure wind speed and direction.
  • A hydrometer is used to measure the relative density of liquids.

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.

Earth rotates from ______________.

  1. East to west

  2. West to East

  3. North to South

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

West to East,

Earth's rotation is the rotation of Planet Earth around its own axis. Earth rotates eastward, in prograde motion. As viewed from the north pole star Polaris, Earth turns counterclockwise.
Because Earth rotates on its axis from west to east, the Moon and the Sun (and all other celestial objects) appear to move from east to west across the sky. Viewed from above, however, the Moon orbits Earth in the same direction as our planet rotates.

A column of air 1 sq. em. in cross-sectional area extending from sea-level to the top of the atmosphere weights approximately.

  1. 933 g wt

  2. 1013 g wt

  3. 1136 g wt

  4. 1360 g wt
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Standard atmospheric pressure at sea level is approximately 1013.25 millibars, which corresponds to a force of about 1033 grams per square centimeter. 1013 g wt is the standard accepted value in many physics textbooks for this calculation.

The stratosphere is said to be ideal for flying jet aircraft because ____________________.

  1. the aircraft in this layer goes out of the firing range of antiaircraft gun

  2. the layer is free from violent weather change

  3. the temperature is constant and ideal for aircraft engine efficiency

  4. All of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The stratosphere is characterized by stable, stratified air and a lack of convective weather patterns, making it ideal for smooth flight. While temperature is stable, the primary reason for its suitability is the absence of turbulent weather.
