which two gases war in earths atmosphere right after earth was formed
A. oxygen
B.helium
C.nitrogen
D.hydrogen

Answers

Answer 1

Answer:

C and D

Explanation:

Answer 2

Given that hydrogen and helium made up the majority of the gas in the dusty, gaseous disk from which the planets originated, Earth's primordial atmosphere was most likely composed only of these two elements. It was extremely hot on Earth and in its atmosphere. Molecules of hydrogen and helium move really fast, especially when warm. Thus, options 'B' and 'D' are the correct options.

What are the main gases in Earth's atmosphere?

About 78% of the gases in the Earth's atmosphere are nitrogen, 21% are oxygen, 0.9 % are argon, and 0.1 % are other gases. The remaining 0.1 percent of gases includes trace quantities of neon, water vapor, methane, carbon dioxide, and methane. Based on temperature, the atmosphere is separated into five distinct strata.

The troposphere, which is located between five and ten miles (or seven and 15 kilometers) above Earth's surface, is the layer that is closest to the surface. The troposphere is significantly thinner near the North and South Poles than it is at the equator. The troposphere, which makes up between 75 and 80 percent of the total atmosphere, is where the majority of its mass is located. Along with dust and ash, the majority of the atmospheric water vapor.

Therefore, the term "Golden Age" refers to an era of supreme peace, harmony, security, and prosperity. Peace and harmony ruled throughout this time period since people didn't need to work to eat because the planet gave food in large quantities.

why did North America bought in 1/2 million of African slaves compared to South America, the West Indies and Brazil's 10.2 million. Why was this a strategic move by colonist in North America.

Answers

Answer:

African slaves

Explanation:

North America bought more slaves than compared to South America and the West Indies and Brazil. The reason for this was the involvement of the Atlantic slave trade (transatlantic slave trade). Plantation agriculture was part of the colonial economy. In the 1600s, tobacco planters in North America needed workers. They could not rely on Native Americans. Plantation owners both North and South America wanted a cheap workforce so they looked for the Africans who were shipped in America.

Why is freedom of of religion important?
Please answer in your own words ​

Answers

Answer:

In Democracy in America, Alexis de Tocqueville explains the importance of religious liberty: “Freedom sees in religion the companion of its struggles and its triumphs, the cradle of its infancy, the divine source of its rights. It considers religion as the safeguard of mores; and mores as the guarantee of laws and the pledge of its duration.”

Freedom of religion is a cornerstone of the American experiment. That is because religious faith is not merely a matter of “toleration” but is understood to be the exercise of “inherent natural rights.”

As George Washington once observed: The Government of the United States, which gives to bigotry no sanction, to persecution

no assistance, requires only that they who live under its protection should demean themselves as good citizens in giving it on all occa- sions their effectual support.” And “what is here a right towards men, is a duty towards the Creator,” James Madison wrote in his 1786 Memo- rial and Remonstrance. “This duty is precedent, both in order of time and in degree of obligation, to the claims of Civil Society.”

The model of religious liberty brilliantly designed by Madison and the other American Founders is central to the success of

the American experiment. It is essential to America’s continued pursuit of the ideals stated in the Declaration of Independence, the ordered liberty embodied in the Constitution, and peace and stabil- ity around the world.

The key to America’s religious liberty success story is its constitu- tional order

Religious liberty and a thriving religious culture are defining attributes of the United States, characterizing the American order as much as its political system and market economy.1 From the

earliest settlements of the 17th century to the great social reform causes led by religious congregations in the late 19th century and again in the 20th century, religion has been a dominant theme of American life.

Today, almost 90 percent of Americans say that religion is at least “somewhat important” in their lives.2 About 60 percent are members of a local religious congregation.3 Faith-based organizations are extremely active in providing for social needs at home and in sending aid abroad.

Why does religious liberty matter—to America and to the world?
