Troposphere and Stratosphere quiz

what is the lower most limit of stratosphere

• tropopause

• troposease

• stratopause

• ozonosphere

the average height of troposphere

• 15Km

• 17Km

• 14Km

• 13Km

Answer explanation

The average height of troposphere is 14Km above sea level but it varies from season to season and from place to place

troposphere contains

• pure dry air

• ozone molecules

• water vaopur

• cloud particles

Answer explanation

in addition to dry air, water vapour and cloud particles are found here

the term troposphere literally means

Answer explanation

it has been derived from the greek word, tropos meaning mixing. virtually all the weather phenomena takes place directly in the troposphere

the 'mother of pearl clouds' are occasionally formed in

• upper stratosphere

• upper troposphere

• lower stratosphere

• tropopause

the region between 20 - 30km is known as

• stratosphere

• heterosphere

• homosphere

• ozonosphere

Answer explanation

one important feature of the stratosphereis that it contains the ozone layer. there is a maximum concentration of ozone, a vital gas between 20 to 30km. this region is called ozonosphere

the degree to which water vapour is present in the air is known as

a abrupt change in the lapse rate occurs of about

• 15km

• 15.5km

• 14.00km

• 18km

the elevation of tropopause is

• maximum at poles and minimum at equator

• equal at all regions

• cannot specify

• least at the poles and maximum at the equator

what is the lower most limit of stratosphere

• tropopause

• troposease

• stratopause

• ozonosphere

Answer explanation

The lower most limit of stratosphere is tropopause. this layer is free of water vapour and dust. it extends from 18 to 80 km between 50 and 60 degree latitudes
