The winds on the Earth's surface blow primarily due to :

1 point

The humidity difference created due to the unequal heating of the Earth's surface by the Sun.

The pressure difference created due to the uniform heating of the Earth's surface by the Sun.

The pressure difference created due to the unequal heating of the Earth's surface by the Sun.

The temperature difference created due to the uniform heating of the Earth's surface by the Sun.

Clear selection

The path of the wind flow from the high pressure tropical regions to the low pressure equatorial regions of the earth is curved (not straight). This is due to the :

1 point

Gravitational force applied by the Earth.

The rotation of the Earth about its own axis.

The revolution of the Earth around the Sun

Both due to the rotation of the Earth about its own axis and the revolution around the Sun.

Clear selection

During a cyclone, the weak thatched roofs of houses in villages are generally blown away. This is because :

1 point

Thatched roofs in villages are generally weak that first succumb to the gale winds of the cyclone.

High speed winds is generally accompanied by an increase in pressure.

High speed winds is generally accompanied by a drop in air pressure.

High velocity storm winds transfer enormous kinetic energy to the weak thatched roofs which are ultimately blown away.

Clear selection

What are the name of the instruments used by a meteorologist to measure the wind speed, wind direction and the amount of rainfall?

1 point

Windmeter, Wind Vane and Rain Gauge (respectively)

Anemometer, Wind Meter and Rain Gauge (respectively)

Anemometer, Wind Vane and Rain meter (respectively)

Anemometer, Wind Vane and Rain Gauge (respectively)

Clear selection

Which coastal region of India is most vulnerable to cyclones in terms of both frequency and severity?

1 point

Southern coast bordering the Indian ocean

Western coast bordering the Arabian sea

Eastern coast bordering the Bay of Bengal

Konkan and Malabar coast

Clear selection

What is the name of the seasonal winds, high in water vapour, that blow over India producing copious rainfall and what does it literally mean ?

1 point

Kalbaishakhi, Devastating air ( respectively)

The Loo , Hot air ( respectively)

Monsoon, Seasons ( respectively)

Monsoon, Weather ( respectively)

Clear selection

What are the storms called that ravage the North American coasts and the Japanese coasts ?

1 point

Tornados and Hurricanes (respectively)

Typhoons and Hurricanes (respectively)

Hurricanes and Typhoons (respectively)

Typhoons and Tornados (respectively)

Clear selection

Electric charges are created in the clouds leading to the release of enormous energy in the form of lightning discharge and thunder. How do the clouds get charged?

1 point

The clouds got charged due to the process of electro-magnetic induction.

The clouds got charged due to the interaction with the earth's magnetic field.

The clouds got charged due to the interaction of the charged particles in the solar wind.

Warm air in the clouds rises against the falling rain droplets creating static electricity charges due to friction.

Clear selection

What are the differences between a Cyclone and a Tornado?

1 point

A Cyclone is a much larger circulation of swirling air than a tornado.

Generally a Cyclone has a clear Eye whereas a Tornado does not have any Eye.

Cyclones originate on waters whereas tornadoes originate on land.

Cyclones travel a much longer distance before landfall and lasts for a much longer period than a tornado.

All the above answers are correct.

Clear selection

The origin, development and movement of a cyclone in the far seas can be tracked ( for issuing early warning) by a :

1 point

Low earth orbit remote sensing satellite

High earth orbit communication satellite

Doppler Radar

Buoys equipped with sensors

Clear selection

Which was the most severe cyclone to have ever hit the Odisha coast in recent past?

1 point

Fani of May 5, 2019

Phailin of October 14, 2013

Cyclone of October 29,1999

Amphan of May 21 , 2020

Clear selection

A cyclone raging in a sea is much more powerful and even lasts for weeks than an ordinary thunderstorm formed on the land. Why?

1 point

The cyclone gathers its speed by travelling on the vast open waters of the sea.

The cyclone can travel a longer path on the sea than a thunderstorm on land.

In a cyclone, the heat released due to the condensation of rising water vapours further evaporates water from the sea surface triggering a cyclic process.

A cyclone gets its enormous energy from the sea waves.
