What is the difference between terrae and Maria?
These are bright areas that are higher on the Moon’s surface than maria. They are hilly, mountainous and brighter than maria. Maria appear darker than the terrae as they contain more iron-rich elements. There are few maria on the far side of the moon. Rocks brought back from the Apollo missions have shown they were formed 3-4 billion years ago.
What is the difference between Maria and maria Mare?
Mare (pronounced Mah-ree) is the Latin for sea. Maria is the plural, seas (pronounced Mah-ree-a). While we see much of this when viewed from earth, only 17% of the lunar surface is classed as maria.

What is Terrae made of?
Although the terrae are highly modified, they are composed of rock material that formed very early in the Moon's history by the process of magmatic differentiation. By this process, minerals formed within an igneous melt become segregated according to differences in their physical properties.
Why is the maria dark?
The dark material filling the Maria is actually dark, solidified lava from earlier periods of Lunar volcanism. Both the Maria and the Highlands exhibit large craters that are the result of meteor impacts. There are many more such impact craters in the Highlands.
How old is lunar maria?

What is the difference between maria and highlands?

Why are there no maria on the far side?
They believe that the absence of maria, which is due to a difference in crustal thickness between the near side of the moon and the far side, is a consequence of how the moon originally formed. The researchers reported their results in the June 9 Astrophysical Journal Letters.
How did maria originate?
How did Maria originate? Maria originated when asteroids punctured the lunar surface, letting magma bleed out, forming extensive lava flows.
How did mare Crisium form?
Mare Crisium is a large, dark, basaltic plain on the Moon that filled an ancient asteroid impact. Basaltic plains on the Moon were created by early volcanic eruptions. Mare Crisium was flooded with basaltic lava, a dark, runny lava commonly found on Earth.
What is the largest mare on the Moon?
Oceanus Procellarum: The region towards the western edge of the Moon is dominated by the largest of the lunar seas; Oceanus Procellarum (Ocean of Storms). This is a massive region measuring approximately 1000 miles by 480 miles.
How many maria are on the near side of the Moon?
30%Ancient astronomers believed that the dark areas were actual oceans, which led to the name maria- or “seas” in latin. There is a 30% mare average on the near side and a 2% mare average on the far side.

Why does Mercury not have as many large maria as the Moon?
1) There are few maria on Mercury and they are small. No large impact era like the Moon. Therefore, Mercury must have cooled faster. 2) Cratering is less heavy, more plain region between craters.
Why is Maria darker than Terrae?
Maria appear darker than the terrae as they contain more iron-rich elements. There are few maria on the far side of the moon.

What did Maria Theresa do to the monarchy?
In the face of the opposition of many noblemen, she managed to reduce drastically (except in Hungary) the powers of the various dominions’ estates, which had held the monarchy’s purse strings since time immemorial. In the further process of abolishing tax exemptions held by the great landowners, who dominated those assemblies, she hit on the notion of a “God-pleasing equality.” Yet she did not question the justice of the manorial lord’s claim on the labour of his hereditary subjects. Only many years later did peasant riots in famine-stricken Bohemia, as well as the reported cruelty of Hungarian magnates, cause her to limit the use of forced labour. “The peasantry must be able to sustain itself as well as pay taxes…,” she wrote.

Practical, if not always fiscal, considerations, rather than doctrinaire humanitarianism, guided all of Maria Theresa’s reforms. An enlarged central administration —from which the judiciary was separated in 1749—and a repeatedly reorganized treasury required knowledgeable civil servants and judges; and their training was, to her mind, the sole purpose of higher education. She approved drastic changes that her physician, the Dutchman Gerhard van Swieten, carried through at the universities (such as the introduction of textbooks, the linking of the medical school of the University of Vienna with the embryonic public health service, and the sovereign’s right to veto the election of deans by the faculties) even as he took them out of the hands of the Jesuits, to whose Society she herself was devoted. (She was the last of the Catholic monarchs to close its establishments.) Deeply pious, strictly observant, and intolerant to the point of bigotry, she was moving, nonetheless, toward subordinating the church to the authority of the state.
