Give a explanation.

Answer 1

Answer:

Explanation:

I think it is a precipitate because that is when two solutions react to make a solid. I am not sure of this answer, however, so please correct me if I am wrong. Everybody makes mistakes sometimes. Hope this helped!

Many changes that have happened in American history started with one person standing up for what they believed in and others joining them in their cause. This was the beginning of the civil rights movement as well as the women’s movement. Because these people and groups were willing to stand up for what they believed in they were able to create a stronger country based on equality. Identify a problem in American society that you would fix if you could. Create an action plan to make others aware of the problem and fight for change. Your action plan should first state the problem and the solution you would like to see, give the steps to create awareness, and explain how you will fight to make this change.

A big issue in American society right now is texting while driving. It is the cause of most accidents today. An action plan that could spread awareness and fight for change  is gathering people with the same thoughts as you and make posters and flyers and hang them around so people can see them and join you. The solution I would like to see is less to no people texting and driving and being more aware of the road. This can help reduce accidents everywhere .

As a result of British expansion, which group of immigrants began migrating in the late 18th century to the U.S. mainly settling in
Virginia, Pennsylvania and the Carolinas?

Answers

Answer:scotch-irish

Explanation:

As a result of British expansion, the Irish group of immigrants began migrating in the late 18th century to the U.S. mainly settling in Virgenia, Pennsylvania, and the Carolinas.

Irish immigrants arrived in the United States in the 1840s and 1850s, settling primarily in coastal states like New York, Pennsylvania, and New Jersey and in the west in states like Illinois and Ohio.

When did most Irish immigrants come to America?

The Scotch-Irish settled primarily in the middle colonies, especially in Pennsylvania, where the city of Philadelphia served as a significant port of embarkation. The Scotch-Irish moved south throughout the ensuing decades via the Great Philadelphia Road, which served as the principal settlement route for the interior southern colonies.

Mainly Belfast, Dublin, and Derry were the Irish ports from whence the majority of voyages originated. After the 1830s, the cost of traveling from England decreased as trade between Britain and the US rose. Many Irish people first traveled to Liverpool before continuing on to Boston, New York, and Philadelphia.

Famine was caused by the potato blight, which eliminated the mainstay of Irish food. Peasants were forcibly evicted from their homes and compelled to move, most frequently to North America.

The central and eastern tropical Pacific Ocean are experiencing cooler than average sea surface temperatures.

Which of these events is
described by the statement?

a
EI Nino

ь
La Nina

c
Land breeze

d
Sea breeze

Answers

Answer:

The correct answer is - b. La Nina

Explanation:

The central and eastern tropical Pacific Ocean are experiencing cooler than the average during La Nina which is a weather pattern found in the pacific ocean especially in the central and eastern tropical area.

In this pattern rainfall increases on the ocean with warm waters and decreases in a cooler area of the ocean which is the central tropical pacific. These are opposite conditions to the El Nina weather pattern as El Nina warmer than the average sea surface.

This would be B, La Niña.


Why?
El Niño brings in warmer air, so it wouldn't be that. La Nina causes unusually cold sea. If it helps, try to remember it by thinking the two partners, El Niño is the hot one, and La Niña is the cold one. They're opposites.

Why did many colonists believe there was nothing wrong with slavery?

Answers

Answer:

Well, it's like with Suffragettes, a group of women fighting for the rights of women, well it's not completely like it, however, with the fight for women's rights, society had created a certain mindset, that women were a weaker sex, and that all and any of their value came with how the men saw them, they had no rights and they were thought of to need men. With Slavery, society had created a certain mind set that most people no longer hold, they believed that people of colour were lower than them, that they didn't deserve to have rights. The dehumanized them like they did with people from India, and as they dehumanized the slaves, it was easier for them to be able to treat them so poorly. Society had created this view and everyone else agreed. It was to help themselves and take over. Not to mention that Glory, Gold and Land was so important back then, people really didn't care about others, if they felt like someone wasn't of their status, they treated them poorly. Just like in Harry Potter, the purebloods had all gotten this ideology that they were better than anyone less than them, they taught their children and acted on their beliefs.
