Which of the following names is given to the planetary winds blowing between the tropics?

  1. Monsoon

  2. Polar winds

  3. Westerlies

  4. Trade winds
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The planetary winds blowing between the tropics are known as trade winds. They are found in the lower section of the troposphere near the earth’s equator. Trade winds blow predominantly from the north-east in the Northern Hemisphere and from the south-east in the Southern Hemisphere. More rainfall can be expected within neighbouring landmasses if the trade winds become weaker.

The Westerlies are cold winds that blow towards the poles.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

True,

Westerlies - The directions of the Westerlies are opposite to trade winds and that is why they are also called antitrade winds. They are the cold winds that blow from subtropical high-pressure areas to circumpolar low-pressure areas, towards the poles. They flow from West to East in between 30 and 60 degrees latitudes.

If the direction of the earth's rotation on its axis is east-west, what would be the direction of Trade Wind blowing in Southern hemisphere?

  1. South-West

  2. South-East

  3. North-East

  4. North-West
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In the Northern Hemisphere, warm air around the equator rises and flows north toward the pole. As the air moves away from the equator, the Coriolis effect deflects it toward the right. It cools and descends near 30 degrees North latitude. The descending air blows from the northeast to the southwest, back toward the equator. Similarly, in the Southern Hemisphere, these winds blow from the southeast toward the northwest and descend near 30 degrees South latitude. If the direction of rotation changes the pattern will be a mirror image of the original, hence the Trade Wind in the southern hemisphere will blow from South West towards the equator.

  2. Earthquakes

  3. Cyclones

  4. Tsunamis

C Correct answer
Explanation
Of the given options, the destruction caused by cyclones has affected India the most. They mostly strike the eastern coast of India. Recently, the frequency of the tropical cyclones which hit the eastern coast of India has risen. It can be attributed to Global Warming.
Trees, buildings etc collapse due to strong wind killing many people.
Storm surges are Strong winds push water towards a shore. The low-pressure area in the eye lifts the water surface in the center which as high as 3 to 12 m. It appears like a water wall moving towards a shore. As a result, water enters the low coastal areas and causes severe loss of life and property.
Cyclones may also cause prolonged heavy rains. This may lead to floods causing heavy losses. Water becomes contaminated and people may suffer from various water-borne diseases.
It may block the rail and road transport system as well as telephones and other communication systems.

How many zones have been identified as the most affected by cyclones?

  1. 3

  2. 4

  3. 5

  4. 6
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Although tropical cyclones can occur in many parts of the world, about 75% of all tropical cyclones form in the Northern Hemisphere. The western North Pacific Ocean has the greatest number of storms per year. There are also areas that are not affected by tropical cyclones, such as the South Atlantic where the ocean is too cool.

The following is a listing of specific areas of the world which are affected by tropical cyclones:

Tropical North Atlantic, Caribbean Sea, and Gulf of Mexico.
Eastern North Pacific (from the west coast of Mexico to 180 degrees West)
Western North Pacific (Philippine Islands and the South China Sea extending to 180 degrees East)
Bay of Bengal
Arabian Sea
South Indian Ocean (off the coast of Madagascar extending eastward to the central Indian Ocean)
Northwest coast of Australia extending westward to the central Indian Ocean
South Pacific Ocean from eastern Australia to about 140 degrees West.

Which of the following names is given to the planetary winds blowing between the tropics?

  1. Monsoon

  2. Polar winds

  3. Westerlies

  4. Trade winds
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The planetary winds which blows between the tropics are termed as trade wind. Trade wind move out from the sub tropical high-pressure belt towards equators. In different sections of their path, the condition of temperature, humidity, and density is not uniform.

__________ are strong moisture laden winds  with low pressure at the center surrounded by high pressure.

  1. Cyclones

  2. Tsunamis

  3. Hurricanes

  4. Earthquake
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Cyclones
Cyclones are violent Storms with an intense spiral and accompanied by strong winds and heavy rains. They are caused due to strong winds blowing around the central area having low atmospheric pressure.

Causes of cyclones
As we know that when water vaporizes, it absorbs heat from the surroundings. Water vapor rises in the atmosphere where it cools down. When water vapor changes back into liquid the heat is released into the atmosphere. This warms the air around it.

The warm air tends to rise and causes a drop in the pressure. The air moves from surrounding high-pressure areas to the central low-pressure area. This cycle is repeated. The chain of events leads to the formation of very low-pressure system surrounded by with very high-speed winds. This weather condition is a cyclone.
