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: (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.

c) Stratosphere

d) Ionosphere

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.
