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 Maria.
What are lunar highlands?
Lunar Highlands
● Elevated areas on the moon’s surface. ● The lunar highlands are the lighter areas on the moon visible to the naked eye. ● Riddled with craters.
Where are the lunar highlands?
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 did the lunar highlands form quizlet?
How did the lunar highlands form? As the molten Moon gradually solidified, lower-density rock floated to the surface and ultimately became the lunar highlands.
What is true about the lunar highlands quizlet?
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.
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.
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.
What are lunar highlands and how did they get their name?
These meteorites formed from fragmental debris near the surface of the Moon. The lunar highlands represent the ancient lunar crust that has been gardened extensively by meteoritic bombardment, particularly during the early period of intense bombardment around 3.9 Ga ago, resulting in extensive brecciation.
What is the difference between lunar 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.
What rocks make up lunar highlands?
Anorthosite
Anorthosite is an important rock type on the surface of the Moon as it makes up most of the lunar highlands and crust. This sample collected by the astronauts of Apollo 16 has been determined to be 4.19 billion years old.
What causes lunar phases quizlet?
What causes the phases of the moon? The moon’s phases are caused by the changing angles of the earth’s shadows and reflected sunlight as the moon revolves around the Earth over the course of about 1 month (28 days). An imaginary line where the Earth is tilted. You just studied 9 terms!
How was the lunar soil created quizlet?
Billions of years of impacts breaking up the rocks and scattering the debris over the surface have created lunar “soil.” Enough impacts have occurred to cover much of the surface with sand- and dust-sized particles.
What evidence shows that the lunar highlands are older than the lunar maria?
Two pieces of evidence that indicates the lunar highlands are older than maria is that maria has few craters, and the highlands have large and more common.
What make up the highlands and lowlands of the Moon?
The highlands are anorthositic in composition, whereas the maria are basaltic. The maria often coincide with the “lowlands,” but it is important to note that the lowlands (such as within the South Pole-Aitken basin) are not always covered by maria.
What are mountains on the Moon called?
In addition to giant craters and sweeping lava fields, the moon is home to some pretty massive mountains. Up there, the mountains are referred to as massifs.
What occurs during lunar eclipse?
During a lunar eclipse, Earth comes between the Sun and the Moon, blocking the sunlight falling on the Moon. There are two kinds of lunar eclipses: A total lunar eclipse occurs when the Moon and Sun are on opposite sides of Earth. A partial lunar eclipse happens when only part of Earth’s shadow covers the Moon.
How are highlands formed on Earth?
The world’s tallest mountain ranges form when pieces of Earth’s crust—called plates—smash against each other in a process called plate tectonics, and buckle up like the hood of a car in a head-on collision. The Himalaya in Asia formed from one such massive wreck that started about 55 million years ago.
What color are lunar highlands?
red
Areas appearing red generally correspond to the lunar highlands, while blue to orange shades indicate the ancient volcanic lava flow of a mare, or lunar sea.
What elements are most common in the lunar highlands?
The lunar basalts, relatively rich in iron and many also in titanium, are found in the maria. In the highlands the rocks are largely anorthosites, which are relatively rich in aluminum, calcium, and silicon.
Do the lunar highlands contain active volcanoes?
This activity was originally thought to have petered out about 1 billion years ago, but more recent evidence suggests that smaller-scale volcanism may have occurred in the last 50 million years. Today, the Moon has no active volcanoes even though a significant amount of magma may persist under the lunar surface.
What is the real name of lunar?
