Many U.S. farmers from the Great Plains left their farms and migrated to California in the 1930s becuse of ____.
A.) the excessive high cost of new farm machinery B.) federal and state assistance programs available to farmers in California C.) drought and dust storms that destroyed their crops D.) the availability of factory jobs in California
Dust storms and drought, caused the sky to be darkened by cloud and dust so there was no way for crops to grow or live.. So I am going to choose option "C".. Farmers did not believe the storms would stop so they also sold their land.. I hope this answer has helped feel free to ask more..
