Explain the first duty of the missionaries.

Hello,

The duty of missionaries is to invite people to follow there religion. I am a muslim so i will explain our missionaries. As a muslim your are required to go to a missionarie once in your life its not that hard. You can start by going to another citie to another country. In arabic missionarie is called ( Jamat ).

the causes of the dust bowls were severe droughts,   lands became dry and hard, temperature was higher than usual, hot and dry conditions killed crops, high winds. because of those factors, the winds kicked up dry soil and created clouds of dust.
