In the early 1950's, Stanley Miller and Harold Urey conducted a series of pioneering laboratory experiments involving simulations of the early Earth. What did these experiments reveal

Answers

Answer 1

Based on historical and scientific records, the Stanley Miller and Harold Urey experiments reveal "that several organic compounds could be formed spontaneously by simulating the conditions of Earth's early atmosphere."

The Stanley Miller and Harold Urey experiments in 1950 were conducted to prove whether organic life can form from inorganic.

Following the experimentation, one of their significant findings was that numerous organic amino acids were formed spontaneously from inorganic raw materials.

Hence, in this case, it is concluded that the correct answer is "that several organic compounds could be formed spontaneously by simulating the conditions of Earth's early atmosphere."

Which layer of earth is liquid

Answers

Answer:

The Outer Core & Inner Mantle

Explanation:

The crust and the inner core are solid, whereas the outer core and inner mantle are liquid. The outer mantle is semi solid. The inner core is solid due to the massive pressure on it. Scientists theorize that the heat of the solid inner core is keeping the outer core in a semi-liquid state which allows the inner core to spin at a slightly different rate than the rest of the earth. This gives the earth its magnetic poles which diverts damaging cosmic rays from colliding with earth. The theories are the result of measurements during volcanic activity and sound waves. The mantle is a plastic solid of varying densities which allow convection currents to flow molten rock towards the earth's surface resulting in volcanic activity, tectonic plate movement, earthquakes, and movement of continents.

there has been multiple ice ages on earth. what causes ice ages?

Answers

The onset of an ice age is related to the Milankovitch cycles - where regular changes in the Earth's tilt and orbit combine to affect which areas on Earth get more or less solar radiation. When all these factors align so the northern hemisphere gets less solar radiation in summer, an ice age can be started.

Answer:

The variation of sunlight reaching Earth is one cause of ice ages. .

Explanation:

When less sunlight reaches the northern latitudes, temperatures drop and more water freezes into ice, starting an ice age.

When more sunlight reaches the northern latitudes, temperatures rise, ice sheets melt, and the ice age ends.

Explanation:

Both Jews and Muslims consider Jerusalem to be a sacred city. However, Jerusalem am and the wider Palestine region has been conquered numerous times by foreign powers.

At various times in history, it has been ruled by Romans, Egyptians, Byzantines, the Abbasid, Seljuk, Ottomans, and the British Empire.

The Jews consider the region as The holy land where their forefathers lived. Muslims only consider Palestine as the third-holiest place in the religion while for Jews it is not just about religion but about an ancestral home that they lost.

In the last 1500 years the area has mostly been ruled by Muslims and before that, only for a short period was it controlled by Jews themselves.

Yet, after the British Empire disintegrated, both Muslims and Jews laid claim to the land. Jews saw it as an opportunity to go back to their homeland, while Muslims believed that they could make their own country, free of foreign control.

Herein lies the problem, for both communities it is not just about religion but a matter of survival.

Below the mask of religion, there are obvious undertones to nationalism, survival, and to a lesser extent racial superiority from both sides.

Matters have only worsened due to Arabs losing two wars with Israel, which led to Israel annexing Egyptian, Syrian and Jordanian territory.

How do you convince two people to give up a piece of land which both belief is not only integral to their religion but to their survival as a nation?

Answer:

Americans were “pushed” west for many reasons. Many Americans felt like they were missing job opportunities in eastern states. Others felt that they were treated unfairly, and many believed that there wasn’t enough land to meet their needs. They were also “pulled” to the west by factors like new land, plentiful resources, and a desire for adventure.

hope it helps you…

People in the United States felt "pushed" west because they were missing out on employment options in the eastern states. New land, and an abundance of resources, were additional elements that "pulled" them toward the west.

What is migration?

When people from one location move or transferred to another location in search of livelihood and seek better opportunities for the future to have financial stability in life along with security is considered migration.

Economical reasons, such as a lack of employment and economic opportunity, motivate people to leave their homes and relocate elsewhere, whereas pull factors draw migrants to new locations for bringing positive change in their lifestyle.

A poor standard of living and a shortage of food, land, or employment opportunities are some factors that cause individuals to leave their homeland. Immigrants may run into problems along the way as they attempt to move.
