What best describes the highlands of the Moon?

What best describes the highlands of the Moon?

The moon’s highlands are its old, mountainous regions. They are light in contrast to the moon’s maria. The highlands consist primarily of anorthosite. Anorthosite is an igneous rock that forms when lava cools very slowly.

What are highlands and lowlands on the Moon?

The dazzlingly bright psrtions of the lunar surface are the highlands, while the dark areas arethe lowlands, of comparatively low reflecting-power. They are the great maria or seas.

What are the regions on 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).

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.

Why are they called seas on the Moon?

Map of the Moon If Its “Seas” Were Really Seas Wikipedia explains that: The lunar maria 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 theory best describes the Moon’s origin?

What theory best describes the moon’s origin? The theory that best describe the moon’s origin is called the collision-ring theory . Scientific theorize that a planet-sized object collided with Earth to form the moon .

What are the lunar lowlands 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 types of terrain are found on the Moon?

There are two primary types of terrain on the Moon: the heavily cratered and very old highlands and the relatively smooth and younger maria. The maria (which comprise about 16% of the Moon’s surface) are huge impact craters that were later flooded by molten lava.

How are lunar highlands formed?

The Indian mission through the Moon mineralogy mapper has offered proof that the Moon’s highlands were formed by the eruption of a hot liquid inside the Moon’s surface popularly known as magma. “The hot liquid, magma, seems to have flowed on to the surface and taken the form of lava.

What are the parts of the Moon?

In Brief, What is the Moon Made Of? Well, Here are the Components of the Moon

• Soil.
• Rocks.
• Craters.
• Valleys.
• Water bodies.
• Mountains and highlands.
• Islands.
• Catena – chain of craters.

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 causes seismic activity on the Moon?

The deeper quakes are caused by tidal forces with the Earth and tended to occur in clusters. The shallow events have tectonic origins. Although more rare than deep events, the shallow events were larger, with body wave magnitudes > 5.5 and stress drops exceeding 100 MPa.

How do lunar maria differ from lunar highlands?

The lunar highlands have more craters, so they are older than maria. The side of the Moon that faces away from the Earth, often called “the dark side of the Moon,” is mainly covered with lunar highlands. This may mean that the crust on this side is thicker.

What is the mare of the Moon?

Lunar mare . The lunar maria /ˈmɑːriə/ (singular: mare /ˈmɑːreɪ/) are large, dark, basaltic plains on Earth’s Moon, formed by ancient volcanic eruptions. Aug 28 2019

What is a lunar highland?

Lunar highlands, on the other hand, also called terrae, are the light colored parts of the Moon. Again, early astronomers believed that terrae were the “drier” areas of the Moon. About 85% of the Moon’s surface is covered by lunar highlands. The lunar highlands have more craters, so they are older than maria.

What is the landscape of the Moon?

The landscape of the moon is full or craters made from meteor strikes. It has dead volcanoes and lava flow.
