Explanation:
The concentration of air molecules and pressure of it on the earth surface is called as air pressure. The average air pressure at sea level is 1013.25mb.Altitude, temperature has a very significant relationship with air pressure. When temperature increases air pressure decreases and when temperature decreases air pressure increases.
Like with increasing altitude air pressure decreases. As in maximum height the concentration of air molecules become light and it reduces the pressure in the atmosphere. Oxygen concentration and water vapour also decreases with increasing altitude.
Answer:
A
Explanation:
In the early 19th century, British traders centred on the illegal importation of opium into China from India as a means of paying for the British purchases of tea and silk. The British used Chinese objections to opium importation as a pretext to
invade China and forcibly open it to Western trade. Chinese attempts to halt the opium trade, which had caused social and economic disruption, started the first Opium War (1839–42) between Britain and China. Britain’s victory in this conflict forced the Chinese create five treaty ports in which foreigners could live and work outside Chinese legal jurisdiction, trading with whomever they pleased.
