Answer:

The earth is made out of layers that separate according to their densities.

The density of each layer is affected by the composition of the material and the amount of pressure it is under.

The thinnest and least dense layer is known as the Crust.

The layer under the most pressure is known as the core.

Such high amounts of pressure cause this layer to remain in a Solid State of matter even though the nickel and iron are at such a high temperature.

On the other hand, the outer core remains in a molten state of matter even though it is made out of the same materials as the inner core since there is not enough pressure to change it to a solid.

Explanation:

The above question now updated with the missing words provide information about how the compositional layers of the earth's crust are formed.

The three major determinants as already explained about how the layers have come to be are:

Composition of Material
Pressure on the material
and their density

The Crust (which is the outmorst layer) comprises of more silica.

The Mantle is a combination of silica, magnesium, and iron.

The core is a combination of oxygen, nickel iron and sulphur.

Who inspired the French people with a sense of nationalism during the Hundred Years’ War? A. Gutenberg B. Charlemagne C. Martin

lara [203]

Answer:

Explanation:

Joan of Arc was a French peasant who claimed she'd had visions of saints and an angel that told her to help restore France from domination by the English.

Joan of Arc came to the scene at a critical time in 1429. The northern half of France was essentially under the control of the English. There was contention over who was truly the French king after Charles VI had died in 1422. His son, the prince Charles, was a claimant to the throne. But the English contended their boy king, Henry VI, should rule over France.

In January 1429, Joan (age 17) came to the court of the prince, Charles, and convinced him of her mission from God. Within a few months, she had rallied the people of France and helped to break the control of the English over large sections of French territory. She ultimately was captured by a group of French nobles who were allied with the English, was handed over to the English, and was burned at the stake (in 1431). But she had done much to unite the French people around a sense of common patriotism and national aspirations.
