The highlands are heavily cratered and mountainous. We have learned that the cratered 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.
How are highlands on the Moon 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 highlands on the Moon made of?
The maria are composed predominantly of basalt, whereas the highland regions are iron-poor and composed primarily of anorthosite, a rock composed primarily of calcium-rich plagioclase feldspar.
What type of rock are the highlands on the Moon?
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 best describes the highlands of the Moon?
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?
The chain of volcanic islands collided with the Grampian Highlands about 480–460 million years ago. This is called the Grampian Event. Baltica collided with the Northern Highlands about 440 million years ago, pushing together the Northern Highlands and North-west Seaboard. This is called the Scandian Event.
Whats the definition of highlands?
high·land ˈhī-lənd. : elevated or mountainous land.
What does highlands consist of?
Highlands or uplands are areas of high elevation such as a mountainous region, elevated mountainous plateau or high hills.
What is true about the Moon’s highlands?
Compared to geology of the Lunar Highlands: ● Lunar highlands have more impact craters than the mare. So, the highlands are older. They are the same age as the highlands because both features were formed by the hardening of lava. Also, they are mafic in composition, which means they were created by magma.
What are 3 main types of landforms found on the Moon?
While the craters, highlands and maria are the moon’s three main landforms, the moon’s surface has a number of other highly visible features. For example, some impact craters have bright rays that shoot outward from the center. Also, the moon has a number of rilles, which are long, thin tunnels or trenches.
What are the 4 types of rocks that are found on the Moon?
There are four types of rocks commonly found on the Moon: Basalt, Breccia, Highlands, and Regolith (or surface soil). The rocks on the Moon are the result of impact events, or meteoric collisions, throughout the Moon’s history.
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 the importance of highlands?
Answer and Explanation: Highland regions provide various important aspects to geography and ecosystems. They serve as sources of minerals as high mountains are subject to weathering phenomena which are enhanced by the slopes and steepness of the geological structures.
How high are the highlands of the Moon?
2.5 to 3 miles
The Apollo astronauts observed that the highlands are generally about 4 to 5 km (2.5 to 3 miles) above the average lunar surface elevation, while the maria are low-lying plains about 2 to 3 km (1.2 to 1.8 miles) below average elevation.
What are highlands Moon NASA?
Lunar Terrain
The light areas of the Moon are known as the highlands. The dark features, called maria (Latin for seas), are impact basins that were filled with lava between 4.2 and 1.2 billion years ago.
What are highlands in space?
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.
Where exactly are the Highlands?

By far the largest region in Scotland, the Highlands covers nearly 10,000 sq miles in northern Scotland. The region is home to stunning scenery, including the legendary Loch Ness.
How old are the Highlands on the Moon?
It also established that the intense cratering of the highlands occurred more than 3.8 billion years ago. Most highland samples have ages in the range 3.8–4.3 billion years.
