Poor farming techniques and drought caused the formation of the in the great plains of the united states in the 1930s. this phenomenon made the land vulnerable to erosion and also led to the displacement of many people living in the great plains. today farmers plant trees and shrubs known as to control erosion in vulnerable areas. first drop down menu: dust bowl, sand bowl, particle bowl second drop down menu: wind, wave, glacial third drop down menu: wave breaks, wind breaks, glacial brakes

The correct options are:  "dust bowl - wind - wind breaks"

The dust bowl effect was caused by persistent drought conditions, favored by years of soil management practices that left it susceptible to the action of wind forces. The soil, stripped of moisture, was lifted by the wind in great clouds of dust and sand so thick they hid the sun.

The following year, 1937, President Roosevelt ordered the planting of "belts" of trees to protect the soil from erosion caused by the wind. The trees were planted along the fences that separated the properties or between the fields forming "windbreaks". The plan would last several years and in 1942 about 220 million trees had already been planted.

freeborn women in ancient rome were citizens (cives), but could not vote or hold political office. because of their limited public role, women are named less frequently than men by roman historians. but while roman women held no direct political power, those from wealthy or powerful families could and did exert influence through private negotiations. exceptional women who left an undeniable mark on history range from lucretia and claudia quinta, whose stories took on mythic significance; fierce republican-era women such as cornelia, mother of the gracchi, and fulvia, who commanded an army and issued coins bearing her image; women of the julio-claudian dynasty, most prominently livia (58 bc-ad 29), who contributed to the formation of imperial mores; and the empress helena (c.250–330 ad), a driving force in promoting christianity.

women in the ancient greek world had few rights in comparison to male citizens. unable to vote, own land, or inherit, a woman’s place was in the home and her purpose in life was the rearing of children. this, though, is a general description, and when considering the role of women in ancient greece one should remember that information regarding specific city-states is often lacking, is almost always from male authors, and only in athens can their status and role be described in any great detail. neither are we sure of the practical and everyday application of the rules and laws that have survived from antiquity. we do know that spartan women were treated somewhat differently than in other states. for example, they had to do physical training like men, were permitted to own land, and could drink wine.
