C Correct answer
Explanation

The Doldrums, or Intertropical Convergence Zone (ITCZ), is a low-pressure belt near the equator characterized by calm winds and rising air.

In 1805, Admiral Francis Beaufort devised a guide to assess the speed and force of wind. It is called the ___________.

  1. Richter Scale

  2. Kelvin Scale

  3. Beaufort Wind Scale

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

A numerical scale for relating wind speed and sea state, devised by the British Admiral Sir Francis Beaufort in 1805. Beaufort numbers (or forces) range from force 0 (calm) to force 12 (hurricane). Sometimes (and originally) called the Beaufort scale of wind forces.

The velocity of winds is governed by ______________.

  1. temperature

  2. rotation of the Earth

  3. pressure gradient

  4. All the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Winds originate due to the pressure gradient i.e. winds travel from higher pressure region to the lower pressure region. The more the pressure gradient, the greater will be the wind speed and vice-versa. Hence option C is correct.
  • Rotation of the earth may affect wind direction eg Ferrel's law, but they do not govern the wind speed.

Which pressure belts are called the horse latitudes?

  1. Equatorial Low Pressure Belt

  2. Sub-Tropical High Pressure Belt

  3. Sub-Polar Low Pressure Belt

  4. Polar High Pressure Belt
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Sub-Tropical high pressure belt,

The horse latitudes are located at about 30 degrees north and south of the equator. It is common in this region of the subtropics for winds to diverge and either flow toward the poles (known as the prevailing westerlies) or toward the equator (known as the trade winds). These diverging winds are the result of an area of high pressure, which is characterized by calm winds, sunny skies, and little or no precipitation.

According to legend, the term comes from ships sailing to the New World that would often become stalled for days or even weeks when they encountered areas of high pressure and calm winds. Many of these ships carried horses to the Americas as part of their cargo. Unable to sail and resupply due to lack of wind, crews often ran out of drinking water. To conserve scarce water, sailors on these ships would sometimes throw the horses they were transporting overboard. Thus, the phrase 'horse latitudes' was born.

Which pressure belt is also known as the 'doldrums'?

  1. Equatorial low pressure belt

  2. Sub-Tropical high pressure belt

  3. Sub-Polar low pressure belt

  4. Polar high pressure belt
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Equatorial trough of low pressure is the zone of convergence of trade winds blowing equatorward from the sub-tropical belts of high pressure in the northern and southern hemisphere. Within this belt the winds are light and variable with frequent calms. That is why this belt is also known as doldrums.

In the northern hemisphere, due to Ferrel's law the wind is deflected  ______.

  1. Towards its right

  2. Towards its left

  3. Towards its north

  4. Towards its south
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ferrel's law states that due to the Coriolis effect caused by the Earth's rotation, winds are deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

What does the word doldrum means?

  1. The zone of severe wind

  2. The zone of no wind

  3. The zone of torrential rain

  4. The zone of storms
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The trade winds blow equatorward from the sub-tropical belts of high pressure in the northern and southern hemispheres. Within this belt, the winds are light and variable with frequent calms. That is why this belt is called the doldrums. The word doldrum means the zone of no wind.

Consider the following statements.
1. The sub tropical high-pressure belts exists at 30 degree north latitude and 30 degree south latitude.
2. The polar high-pressure belt experiences severe cold throughout the year. As a result, the air remains chilled under the extreme cold that prevails over the poles.

  1. only 1

  2. only 2

  3. both 1 and 2

  4. neither 1 nor 2

The air is colder at this zone. Though the cold air remains close to the earth, the air is thrown up due to the rotation of the earth.As a result,low pressure is experienced all along this zone.
The zone here refers to _________________.

  1. Equatorial low pressure belt.

  2. Sub tropical low pressure belt.

  3. Sub Polar low pressure belt.

  4. Polar low pressure belt.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The sub-polar low-pressure belt (around 60-65 degrees latitude) is created where warm westerlies meet cold polar easterlies, causing the warmer air to rise and creating a low-pressure zone.

The north-facing side of a hill in a mountainous region in the US tends to:

  1. Receive less sunlight during a year than the south-facing side

  2. Grow a variety of trees that are typically observed at higher elevation

  3. Be a better location for a ski run than the south-facing side

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In the Northern Hemisphere, north-facing slopes receive less direct sunlight, are cooler, often support different vegetation (higher elevation types), and are better for retaining snow for skiing compared to south-facing slopes.

To stay away from the intense heat during the day, they stay in _____ deep in the sand.

  1. Burrows

  2. Water

  3. Grass

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

To stay away from the intense heat during the day, they stay in burrows deep in the sand. These burrows stay cool in the day and hence protect these animals from hot weather.
