Answer: Option B. -> The air pressure in the bottle is greater than the outside pressure.
:
B
As we press the bottle, theair pressure inside the bottle becomesmore than the pressure outside. Thus, a paper ball kept near the mouth of the bottle will be pushed out due to this pressure difference.

Answer: Option C. -> Amritsar
:
C
Cyclones largely affect the coastal regions. As it can be observed that all the places except Amritsar are on coastal area, Amritsar will not be affected.

Answer: Option B. -> rain
:
B
The winds carrying water vapour brings rain.Rain is the liquid water in the form of droplets that have condensed from atmospheric water vapor and then precipitated.

Answer: Option A. -> Anemometer
:
A
An anemometer is a device used for measuring wind speedand is a common weather station instrument. The term is derived from the Greek word anemos, which means wind, and is used to describe any wind speed measurement instrument used in meteorology.
Barometer measures pressure.
Thermometer measures temperature.
Ammeter measures electric current.

Answer: Option A. -> Earthquake
:
A
Thunderstorms are usually associated with winds athigh speed, lightning and rain. Earthquake is an altogether different phenomenon related withEarth's tectonic plate movements.

Answer: Option A. -> True
:
A
The density of warm air is lesser than cold air. On heating, air expands andits density decreases.

Answer: Option C. -> Satellites help in predicting the path of cyclone.
:
C
During night, the winds flow from the land to ocean and this is known asland breeze.During daytime, the winds flow from the ocean to landand this is known as seabreeze.
Satellite images help to predict the path of cyclone to some extent. The whole system of clouds and winds spinning at high speed is captued by satellites.
The coastline of India is vulnerable to cyclones as cyclones form over the sea.

Answer: Option B. -> To decrease the air pressure difference between the two faces of hoardings.
:
B
In windy conditions, the air pressure differenceover the two faces of a hoarding can create a massive force. This force can easily topple or destroy the huge hoardings. Holes in the material allows the wind to pass through whichgreatly reducesthe overall pressure difference on the structure.

Answer: Option B. -> typhoon
:
B
A cyclone is also called as typhoonin Philippines and Japan.
It is calledhurricanein the American continent.
Tornadoes are also circular winds but they are much faster and narrower than cyclones.
Thunderstormisnot a cyclones rather it is astorm with thunder and lightning.

Answer: Option A. -> Satellites
:
A
The useof satellites in disaster management is becoming more integral in reducing reaction time and providing accurate information for rescue and disaster control operations. Satellites are used in disasters for communication, remote sensing and mapping. Meteorological and storm warning satellite technology can help in predicting disasters and setting up precautionary activities.
