when and how did the earth originate?​

Answers

Answer 1

Answer:

Earth is the largest of the inner planets and was created like all the remaining planets in the Solar System, approximately 4.6 billion years ago. The early Earth was formed by the collision and fusion of smaller rock fragments, the so-called planetesimals

Explanation:

Scientists estimate that the Earth began to form about 4.6 billion years ago. Protoplanets had to experience various collisions, so that the Earth as a planet originated from the collision of several protoplanets. Each collision released a large amount of energy, and the larger protoplanets contracted under their own gravitational influence. A last collision caused the creation of a celestial body the approximate size of the present Earth, that has received the name of proto-Earth. The early Earth was a hot volcanic body. The metal reached the melting point and the denser material sank and formed the core, while the lighter materials rose and became the mantle and crust. This is how the layers of the Earth were formed. Little by little the planet lowered its temperature, many of the impact craters were covered with water, photosynthetic organisms appeared and an atmosphere was formed, all of which would give the conditions that make the planet the place of life.

Answer:

There may be a sizable gap between rich and poor people.

Citizens must pay for most basic necessities by themselves.

There is no guarantee of steady employment for many citizens.

Citizens often purchase their own health care and higher education.

Explanation:

just took test

The cons of a 'mixed market economy' for the majority of citizens include:

A). There may be a sizable gap between rich and poor people.

C). Citizens must pay for most basic necessities by themselves.

D). There is no guarantee of steady employment for many citizens.

F). Citizens often purchase their own health care and higher education.

'Mixed market economy' is characterized as the economy that contains the characteristics of both the capitalistic, as well as, socialist principles.

The three key characteristics of such an economy are:

Presence of both the public and private enterprises. Strong regulatory oversight over the private sector. Economic planning and interventionism to maintain equilibrium.

However, this leads to several cons as well.

Unequal distribution of goods leads to the widening gulf between rich and poor. The existence of private enterprises and their protection enhances competition, leading people to pay for the majority of the things. Competition is another cause of unguaranteed employment.

Although you did not provide some context or any particular reference, we can comment on the following.

The privileges I think I deserve, but you haven't been allowed yet are to get my own car, making my own decisions to drive my life, and create my own heritage.

But I have to get in mind that to have those privileges, I need to understand that I have obligations too. And it is a matter of time and experiences to grow, prosper, and thrive.

I have been taught that for every privilege, there is a responsibility.

Describe at least 2 similarities and differences between an Ancient Roman circus and the ones that still survive today.

Answers

The correct answer to this open question is the following.

The two similarities and differences between an ancient Roman circus and the ones that we see today are the following.

Similarities.

1.- Both were made for entertainment purposes, although entertainment in ancient Rome times meant something very different and cruel.

2.- It included people, acts, and animals, although as I said above, the shows were cruel, aggressive, bloody, and deadly.

Differences.

1.- The circus seated thousands of people. The circus buildings like the one in Rome were huge. According to historians and archeologists, these circuses seated 15,000 people (The small ones) to 80,000 to 100,000 people as was the case of the Roman Circus.
