What Is True Of The Lunar Highlands

What is true of the lunar highlands? They are the oldest part of the lunar surface. they range from 4.6 – 4.4 billion years old, on average. the Moon lacks wind, water and an atmosphere.

What are the Lunar Highlands?, highlands: the lighter, heavily cratered regions of the Moon, which are generally several kilometers higher than the maria. mare: (plural: maria) Latin for “sea;” the name applied to the dark, relatively smooth features that cover 17% of the Moon’s surface.

Furthermore, How do lunar maria differ from lunar highlands?, How do maria differ from highlands. Maria are darker, less cratered, smoother, younger, higher in iron, and generally lower in elevation than the highlands. What are lunar rilles. Lunar rilles are river-like valleys and were most likely formed when lava flowed on the lunar surface.

Finally,  What is two special features of highlands on the Moon?, There are two main types of lighter-colored highlands on the moon—montes, which are mountain ranges, and mons, which are isolated single mountains. Probably the most well-known features of the moon are craters. Craters are very round basins that can be one inch or hundreds of miles across.

Frequently Asked Question:

What are the features of the lunar lowlands?

The lunar landscape is characterized by impact craters, their ejecta, a few volcanoes, hills, lava flows and depressions filled by magma.

What are the features of the lunar highlands?

The highlands have low, rounded profiles that resemble the oldest, most eroded mountains on Earth (Figure 3a). Because there is no atmosphere or water on the Moon, there has been no wind, water, or ice to carve them into cliffs and sharp peaks, the way we have seen them shaped on Earth.

What are the lowlands of the moon called?

The lunar maria /ˈmɑːriə/ (singular: mare /ˈmɑːreɪ/) are large, dark, basaltic plains on Earth’s Moon, formed by ancient volcanic eruptions. They were dubbed maria, Latin for “seas”, by early astronomers who mistook them for actual seas.

What is two special features of highlands on the Moon?

There are two main types of lighter-colored highlands on the moon—montes, which are mountain ranges, and mons, which are isolated single mountains. Probably the most well-known features of the moon are craters. Craters are very round basins that can be one inch or hundreds of miles across.

What kinds of features dominate the lunar surface?

The dominant features of the lunar surface are the old heavily cratered highlands and the younger basaltic maria, mostly filling the large impact basins (see Figs. 1 and 3). There is a general scarcity of tectonic features on the Moon, in great contrast to the dynamically active Earth.

What are the features of the lunar highlands?

The highlands have low, rounded profiles that resemble the oldest, most eroded mountains on Earth (Figure 3a). Because there is no atmosphere or water on the Moon, there has been no wind, water, or ice to carve them into cliffs and sharp peaks, the way we have seen them shaped on Earth.

How are highlands formed on the moon?

“The hot liquid, magma, seems to have flowed on to the surface and taken the form of lava. … The rocky remains that floated to the top appear to have transformed into the Moon’s highlands or mountains,” an Isro scientist explained.

What are the two main geological features of the moon’s surface?

The lunar surface can be divided into two main regions, the highlands and the maria. The highlands make up roughly 83 percent of the moon’s surface, whereas the maria make up about 17 percent of its surface. Both of these regions have a characteristic density of craters from meteor impacts.

What are the highlands on the moon made of quizlet?

The lunar highlands are light-colored areas elevated above the Maria. The highlands are largely made of low-density rocks rich in aluminum. The highlands are much older than the maria and are much more heavily cratered.

How are lunar maria different than lunar highlands?

The Maria are mostly composed of dark basalts, which form from rapid cooling of molten rock from massive lava flows. The Highlands rocks are largely Anorthosite, which is a kind of igneous rock that forms when lava cools more slowly than in the case of basalts.

What are three ways that lunar highlands differ from lunar maria?

How do maria differ from highlands. Maria are darker, less cratered, smoother, younger, higher in iron, and generally lower in elevation than the highlands. What are lunar rilles. Lunar rilles are river-like valleys and were most likely formed when lava flowed on the lunar surface.

What are lunar highlands?

highlands: the lighter, heavily cratered regions of the Moon, which are generally several kilometers higher than the maria. mare: (plural: maria) Latin for “sea;” the name applied to the dark, relatively smooth features that cover 17% of the Moon’s surface.

What are the moon Highlands and Maria?

The highlands are heavily cratered and mountainous. We have learned that the maria are relatively young areas on the Moon which were generated after very large impacts penetrated the crust of our Moon and excavated basins. During later volcanic episodes, liquid magma came to the surface and filled these basins.

What are the highlands of the Moon called?

The face of the Moon turned toward us is termed the near side (image at right). It is divided into light areas called the Lunar Highlands and darker areas called Maria (literally, “seas”; the singular is Mare).

How are lunar highlands formed?

“The hot liquid, magma, seems to have flowed on to the surface and taken the form of lava. … The rocky remains that floated to the top appear to have transformed into the Moon’s highlands or mountains,” an Isro scientist explained.

What is true about the lunar highlands?

What is true of the lunar highlands? A. They are less heavily cratered than the mare. … They are the darker regions of the Moon seen with the naked eye.

How do lunar maria differ from lunar highlands?

How do maria differ from highlands. Maria are darker, less cratered, smoother, younger, higher in iron, and generally lower in elevation than the highlands. What are lunar rilles. Lunar rilles are river-like valleys and were most likely formed when lava flowed on the lunar surface.
