BPPV is an inner ear condition. BPPV is also called positional vertigo or benign (not life-threatening) paroxysmal nystagmus. Nystagmus is a quick, shaky eye movement that you cannot control. BPPV causes sudden attacks of vertigo when you change your head position. Vertigo is the feeling that you or the room is moving or spinning. With each attack of vertigo, you may have nystagmus. The attacks of vertigo and nystagmus last from a few seconds up to 1 minute.
Dust Bowl Facts ~ Great Depression. Here are some interesting facts about the Dust Bowl: â¢In 1932, there were 14 dust storms recorded on the Plains (an area that included the panhandle of Oklahoma and Texas, southwest Kansas, southeastern Colorado, and Nebraska). In 1933, there were 38 dust storms. â¢By 1934, because of years of repeated dust storms, approximately 100 million acres of farmland no longer had enough topsoil to grow crops. â¢In April 1935, an Associated Press reporter used the term âdust bowlâ to describe the conditions, and the term soon became popular.
The main causes of the dust bowl were extreme drought for eight years in total, and also very poor farming techniques on the behalf of the inhabitants. Normally crops are rota â¦ ted (different crops are grown in an area each year or sometimes no crops at all) so as to never deplete soil too much.
