The wind system in the equatorial areas is known as Trades.
The phenomenon of aurora borealis, the display of red and green lights in the northern hemisphere, is due to radiation from Mesosphere.
The doldrums is an area of Low pressure.
The monsoon has a well-developed cycle in South & South East Asia.
Cyclone is the most destructive.
The winds blowing from sea towards the coastal areas are called Sea breeze.
Anticyclones are caused by Winds that blow spirally outwards from the center.
Hurricanes are cyclonic storms in the West Indies and Gulf of Mexico.
Atmospheric pressure exerted on earth is due to Gravitational pull.
The four major components of the atmosphere are Oxygen, Nitrogen, Carbon dioxide, and Argon.
Increase in carbon dioxide in the atmosphere leads to Rise in earth temperature.
Cyclones occur more frequently than the other three in the Indian Ocean.
Monsoon is not a constant wind.
Pampero is a cold wind that prevails in Argentina and Uruguay.
Beaufort scale is used to measure wind velocity.
The plane of contact of the troposphere and stratosphere is known as Tropopause.
When the wind is deflected due to the rotation of the earth, it is called Geostropic wind.
Tornadoes are not a correct example of tropical cyclones.
The jet stream is found in the Troposphere.
Buran is a cold wind.
The dry wind “Santa Ana” blows in California.
The portion of the atmosphere which extends from the earth’s surface up to 6-8 miles and experiences a decrease in temperature at a constant rate is Troposphere.
In the northern hemisphere, currents are deflected to their right due to Coriolis force.
In the northern hemisphere, the wind blowing from the Horse latitudes to the doldrums is called Trade wind.
The lowest layer of the atmosphere is known as Troposphere.
Typhoon has the highest wind velocity.
Nitrogen is the chemically inactive gas present in the atmosphere.
The instrument used for measuring air pressure is Barometer.
The atmospheric level at which the decrease of temperature with height ceases to prevail is Tropopause.
In the northern hemisphere, the winds are deflected To the right.
Winds blow from a region of high pressure to a region of low pressure.
Anticyclones are so called because they move in a direction opposite to that of cyclones.
Oxygen in the upper atmosphere is converted into Ozone.
Typhoons are more frequently experienced in Philippines Islands.
In North America, the hot dry winds that blow on the eastern side of the Rocky Mountains are Chinook.
Exosphere is the uppermost layer of the atmosphere.
A storm accompanied by strong winds revolving round a center of atmospheric low pressure is known as Cyclone.
The proportion of nitrogen in dry air is 78% by volume.
The main cause of the movement in the earth’s atmosphere is Difference in air pressure.
The unit for measurement of atmospheric pressure is Millimetres.
The Horse latitudes are The regions of calm and light variable winds.
The gas in the atmosphere that provides a shield against harmful ultraviolet rays of the sun is Ozone.
The centre of a cyclone is called Eye.
The sea breeze blows during Day from sea to land.
The tropical cyclones of the Bay of Bengal are usually called Depressions.
The percentage of oxygen in the atmospheric oxygen is approximately 20.95%.
The amount of actual water vapour in air is known as Absolute humidity.
Anemometer is an instrument used to Measure wind speed.
Clouds with vertical development are known as Cumulus.
The primary rainbow has an angular radius of 42°.
The instrument used for measuring relative humidity in air is Hygrograph.
Waterfall is not a form of precipitation.
Clear nights are colder than cloudy nights because of Radiation.
A sudden fall in the barometric reading indicates Storm.
The formation of fog occurs when moist air meets cold surface of the earth.
Hailstorm occurs in summer season due to the formation of clouds called Cumulonimbus.
The dense mass of small water drops on smoke or dust particles in the lower layers of the atmosphere is Fog.
Cirrus is a high cloud.
Cirrus clouds are made up of tiny ice particles.
Convectional rainfall is often accompanied with lightning and thunder.
The type of clouds which is the thunder cloud and associated with heavy rain is Cumulonimbus.
Water vapor beyond the dew point results in condensation, leading to the formation of dew, fog, clouds, or precipitation like rain or snow.
