Answers

Answer:

The consequences of the crusades on medieval society were largely cultural and educational, crusaders brought back with them spices, herbs, jewelry, and music, changing the cooking for higher rungs of society and even affecting the beer for commoners and serfs. they also brought back the Arabic system of numbers, allowing scholars and mathematicians to do more complicated equations, bringing forth a new era of science and mathematics in Europe. the crusades also lead to one of the first forms of banking in Europe lead by the Knights Templar, loaning money to rich and poor alike. it also lead to the explosion of popularity of the free masons, traveling stone and wood workers, building bridges and cathedrals. all in all the crusades didn't change much for the common serf of the medieval period, but changed the educated caste of society forever.

How did geography contribute to the economic development of Harappa?

Harappa used the fertile land to hunt animals for trade with other cities.
Harappa used the Indus River to trade and become a major fishing city.
Harappa used floodwater in trade and stored it for later use.
Harappa used fertile land from the Indus River to farm and trade.

Answers

Answer:

your answer is the last one

Explanation:

The annual flooding of the river left behind fertile soil to plant crops like wheat and barley. The rivers were so vital to the success of Mohenjo-daro and Harappa that when some parts of the system dried up, the civilization went into decline

In the economic development of the Harappa,  the contribution that was made by the geographical factors in the form of the fertile land from the Indus River which is used to farm and trade. Hence, Option D is correct.

What are geographical factors?

On the earth's surface, there are various things present which include topography, climate, soil, vegetation, and many more. The study of all such kinds of natural features of a region is known as the geographic factor. All these things exist at a location in the space and at a scale that is relevant to geography.

In simple words, factors that affect the agricultural geography are climate, relief, and soil also has an impact on the river that is present in that area. In the context of the Harappa, it is the river which is named the Indus river that gave support for the fertile land, and that land was further used in the farm and trade.

Thus, Option D is correct.

C

D
Saturn

Answers

Answer:

mars

Explanation:

Mars planets could be accurately described as rocky, terrestrial, and relatively close to the Sun. The correct option is C.

Why is Mars similar to Earth?

Mars and Earth were founded from the same materials and appeared very similar when the solar system settled in with its current layout over four billion years ago. Both have a solid pillar, a rocky mantle, and a solid crust.

The planets Mercury, Venus, Earth, and Mars are referred to as terrestrial because their surfaces are compact and rocky, similar to Earth's terra firma. The terrestrial planets are the solar system's four innermost planets. Mercury, Venus, Earth, and Mars are the four inner planets, or those closest to the Sun. They are smaller and primarily composed of metals and rocks. Jupiter, Saturn, Uranus, and Neptune are the four largest planets and are mostly made up of gases.

Thus, the ideal selection is option C.

The Whigs parted company with Tyler over the issue of a new national ___.
-railroad
-bank
-road
-government

Answers

Answer:

From what I know I will say the answer is bank

Explanation:

Suddenly President Harrison was dead, and "Tyler too" was in the White House. At first the Whigs were not too disturbed, although Tyler insisted upon assuming the full powers of a duly elected President. He even delivered an Inaugural Address, but it seemed full of good Whig doctrine. Whigs, optimistic that Tyler would accept their program, soon were disillusioned.

Tyler was ready to compromise on the banking question, but Clay would not budge. He would not accept Tyler's "exchequer system," and Tyler vetoed Clay's bill to establish a National Bank with branches in several states. A similar bank bill was passed by Congress. But again, on states' rights grounds, Tyler vetoed it.

In retaliation, the Whigs expelled Tyler from their party. All the Cabinet resigned but Secretary of State Webster. A year later when Tyler vetoed a tariff bill, the first impeachment resolution against a President was introduced in the House of Representatives. A committee headed by Representative John Quincy Adams reported that the President had misused the veto power, but the resolution failed.

Answers

Answer:

Explanation:

The Emancipation Proclamation in 1863 freed African Americans in rebel states, and after the Civil War, the Thirteenth Amendment emancipated all U.S. slaves wherever they were. As a result, the mass of Southern blacks now faced the difficulty Northern blacks had confronted—that of a free people surrounded by many hostile whites. One freedman, Houston Hartsfield Holloway, wrote, “For we colored people did not know how to be free and the white people did not know how to have a free colored person about them.”

Even after the Emancipation Proclamation, two more years of war, service by African American troops, and the defeat of the Confederacy, the nation was still unprepared to deal with the question of full citizenship for its newly freed black population. The Reconstruction implemented by Congress, which lasted from 1866 to 1877, was aimed at reorganizing the Southern states after the Civil War, providing the means for readmitting them into the Union, and defining the means by which whites and blacks could live together in a nonslave society. The South, however, saw Reconstruction as a humiliating, even vengeful imposition and did not welcome it.

During the years after the war, black and white teachers from the North and South, missionary organizations, churches and schools worked tirelessly to give the emancipated population the opportunity to learn. Former slaves of every age took advantage of the opportunity to become literate. Grandfathers and their grandchildren sat together in classrooms seeking to obtain the tools of freedom.

After the Civil War, with the protection of the Thirteenth, Fourteenth, and Fifteenth Amendments to the Constitution and the Civil Rights Act of 1866, African Americans enjoyed a period when they were allowed to vote, actively participate in the political process, acquire the land of former owners, seek their own employment, and use public accommodations. Opponents of this progress, however, soon rallied against the former slaves' freedom and began to find means for eroding the gains for which many had shed their blood.

4 bulletin points on Harriet Tubman birth and family!!

Answers

Answer:

Harriet Tubman was born around 1820 on a plantation in Dorchester County, Maryland. Her parents, Harriet (“Rit”) Green and Benjamin Ross, named her Araminta Ross and called her “Minty.”

In 1840, Harriet’s father was set free and Harriet learned that Rit’s owner’s last will had set Rit and her children, including Harriet, free. But Rit’s new owner refused to recognize the will and kept Rit, Harriett and the rest of her children in bondage.

On September 17, 1849, Harriet, Ben and Henry escaped their Maryland plantation. The brothers, however, changed their minds and went back. With the help of the Underground Railroad, Harriet persevered and traveled 90 miles north to Pennsylvania and freedom.

The 1850 Fugitive Slave Act allowed fugitive and freed workers in the north to be captured and enslaved. This made Harriet’s job as an Underground Railroad conductor much harder and forced her to lead enslaved people further north to Canada, traveling at night, usually in the spring or fall when the days were shorter.
