The economy in the Southern colonies was based on

Answers

Agriculture.

Explanation:

The economy in the Southern colonies was based on agriculture. Many Southerners relied on cash crops, plantations, and slave labor for their income.

The South had many plantations that would grow cash crops. Cash crops were crops that sold for a lot of money and were grown for profit. Southern cash crops during this time consisted of cotton, rice, indigo, and tobacco. In order to keep up with the amount of crops that were being grown, many Southerners relied on slave labor to tend to the fields.

After the Civil War, slavery got abolished and it was much harder for the South to continue their usual agricultural practices. The North heavily relied on industrialization during this time, making most of their money from factories, so they did not have to worry about the use of slave labor.

how does liberty's daughters by mary beth norton end

Answers

Answer:

Mary Beth Norton comprehensively examines the behavior and experience of women in America between 1750 and 1800. She explicitly argues against the idea of a "golden age" of women's status in colonial America, instead describing a world of rigid patriarchy in which women's worth was denigrated by themselves and others. In this world, women largely led lives of drudgery, controlled by husbands and fathers and denigrated in popular literature. Women enjoyed only limited freedoms, primarily in religious participation and in their female relationships with daughters, mothers, and female friends.  

Norton describes how the Revolution helped change women's status. During the war, women took on more active political roles by participating in non-importation and boycott movements, signing petitions, and in the famous case of Philadelphia women in 1780, raising money for the Continental Army. At home women were forced to take on more and more responsibilities with men away at war. The net result was a greater degree of public political participation and an increased sense of worth (both of themselves and of society's views of their contributions). After the war saw a limited flourishing of women's conditions: more control over choosing spouses, more mutual cooperation to prevent pregnancies, and most importantly, greater access to education. The end result was, in Mary Norton's characterization, cautiously optimistic. Women made advancements in several areas, although she is careful to note that their role was still tightly circumscribed to the household - it was just that their worth within this area had increased. This stands in contrast to Linda Kerber's interpretation of the era (who published Women of the Republic in the same year, 1980) - which Norton describes as a "half-empty" characterization of the Revolution's effects, compared to her own "half-full" interpretation.

Option: They shot down an American spy plane.

Explanation:

In the 1960s, the Soviet Union shot down a U-2 spy plane and captured its pilot, Gary Francis Powers.

The president was furious for the public humiliation of the United States.

The collapse of the 1960 summit meeting was a shock to both countries, who thought there was a peaceful rapprochement between the two superpowers.

what are two groups who discovered america by crossing the atlantic before columbus? (not the vikings)

Answers

Answer:

Long before America was discovered by Columbus, a band of Irish monks led by Saint Brenden visited Americas in sixth century. They traveled on ox-boats and returned after seven years. They reported that they have discovered a land full of vegetation, people believe that the land he mentioned was Newfoundland.

Some scholars say that before Vikings America was visited by Chinese travelers and also by visitors from Ice Age Europe and Africa.

Answer: First of all, let’s not ignore the fact that the Native Americans arrived in the Americas about 23,000 years ago. Even if these history questions and answers just focused on the first Europeans to arrive, Christopher Columbus still can’t claim the glory. About 400 years before Columbus sailed the ocean blue, Viking Leif Eriksson landed in Canada. (Don’t try arguing that his trip doesn’t count because it was in Canada and not the United States.) Columbus didn’t set foot on any of the 50 states during any of his four trips either—only Caribbean Islands and Central and South America. Other Spanish explorers were the first to arrive in what’s now the United States.

explain how more advanced civilizations were able to develope techonology that allowed their citizens to move away from the river

Answers

The correct answer to this open question is the following.

More advanced civilizations were able to develop technology that allowed their citizens to move away from the river and protected them from flooding.

This technology first, allowed civilization to predict the flooding of the rivers, and then to take advantage of the flooding to increase crop production.

Let's not forget that ancient civilizations such as Sumeria, settled in the middle of two rivers: the Euphrates and Tigris. This represented many advantages to farming but also had its risks, basically, flooding. In the case of ancient Egypt, they settled in the banks of the Nile River, and they were one of the most successful civilizations that developed the kind of technology to avoid disasters due to flooding, and instead, growing good crops. The flooding of the Nile left rich soil to grow quality crops that they traded with other towns. The Egyptians also built underground channels to take the course of the water in times of flooding. Thes minimized the risk of massive flooding of their cities.
