Question : 1 [SSC CGL Pre 2004]
Trade winds blow from the
a) polar high pressure
b) equatorial low pressure
c) subpolar low pressure
d) subtropical high pressure
Answer »Answer: (d)
Wind flows outward down the pressure gradient away from the subtropical highs. As it does so, it encounters the Coriolis Effect caused by the rotation of the Earth.
This force causes the winds in the Northern Hemisphere to move from the east towards the west below the subtropical high, and from the west towards the east above the subtropical high.
The opposite is true in the Southern Hemisphere. Above the subtropical high winds move from east to west, and below the subtropical high winds move from west to the east.
Question : 2 [SSC GL 2013]

a) Troposphere
b) Ionosphere
c) Exosphere
d) Stratosphere
Answer »Answer: (b)
The Radio waves are reflected back to Earth in the Ionosphere which is an electrically charged layer of the upper atmosphere.
This process is used to communicate beyond the horizon, at intercontinental distances, mostly in the shortwave frequency bands.
Question : 3 [CDS 2017]
Which one among the following is a source of methane emission into the atmosphere?
a) Industrial chimney
b) Automobile exhaust fume
c) Wetland
d) Mining
Answer »Answer: (c)
The most significant natural sources of atmospheric methane are wetlands. Wetlands are characterized by waterlogged soils and distinctive communities of plant and animal species that have evolved and adapted to the constant presence of water.
Due to this high level of water saturation as well as warm weather, wetlands are one of the most significant natural sources of atmospheric methane.

a) Mesosphere
b) Troposphere
c) Stratosphere
d) Ionosphere
Answer »Answer: (c)
The ozone layer is a region of Earth’s stratosphere. it is mainly found in the lower portion of the stratosphere, from approximately 20 to 30 kilometres (12 to 19 mi) above Earth.
The ozone layer absorbs 97 to 99 per cent of the Sun’s medium-frequency ultraviolet light (200 nm to 315 nm wavelength), which otherwise would be harmful to exposed life forms on the earth.
