Further, different parts of the surface of the Moon exhibit different amounts of cratering and therefore are of different ages: the maria are younger than the highlands, because they have fewer craters. The oldest surfaces in the Solar System are characterized by maximal cratering density.
Which surface is older the highlands or the maria?
If we look at the highlands, we see that they are covered with lots and lots of craters. This tells us that in general, the highlands are older than the maria, which have fewer craters. We also know that if we see a crater on top of a mare, the mare is older.
Which is older the lunar highlands or lunar lowlands?
Compared to geology of the Lunar Highlands: ● Lunar highlands have more impact craters than the mare. So, the highlands are older.
Are lunar maria older?
The lunar maria (or plains), which were formed between 3.1 and 3.9 billion years ago, are the youngest geologic units on the lunar surface, except for more recent impact craters.
What is the difference between the lunar maria and lunar highlands?
The side facing the earth consists of dark (basaltic) lava filled basins called mare (maria) or seas. The lighter areas are heavily impacted terrain called the highlands. These contrasting features can easily be seen with the naked eye.
How old are the lunar highlands?
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.
How old is lunar maria?
between 3.1 and 3.9 billion years ago
The lunar maria (or plains), which were formed between 3.1 and 3.9 billion years ago, are the youngest geologic units on the lunar surface, except for more recent impact craters. The release of heat from large impacts caused extensive melting and extrusion of basaltic lavas on the moon.
Are highlands or lowlands older?
Discussion: These data are consistent with the results from global studies in that the lowlands are older than the visible highland surface.
Which is the oldest part of the Moon’s surface?
The light colored areas are the oldest part of the Moon’s surface – they have many craters and are called the “cratered highlands.” This part of the Moon’s crust formed from a cooling magma ocean soon after the Moon formed 4.5 billion years ago!
What are the oldest parts of the Moon?
Answer and Explanation: The Lunar Highlands are the oldest features of our moon. These highlands are about four billion years old (the moon itself is considered to be about 4.4 billion years old) and were created by a huge crater after the impact of a large object, most likely a meteor, with the moon.
Why are maria darker than the lunar highlands?
However, the lunar basalts are completely devoid of water and contain few volatile elements. The Moon’s basaltic rocks are fine-grained composed mainly by iron, magnesium and titanium. The maria appear dark due to their high iron and titanium content that lead to about half of the highlands albedo.
What are moon 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.
Why is it called lunar maria?
They were dubbed maria, Latin for ‘seas’, by early astronomers who mistook them for actual seas. They are less reflective than the “highlands” as a result of their iron-rich composition, and hence appear dark to the naked eye. The maria cover about 16% of the lunar surface, mostly on the side visible from Earth.
What created the lunar highlands?
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.
How does the age of the lunar highlands compare to the age of the lunar maria quizlet?
How does the age of the lunar highlands compare to the age of the lunar maria? The maria are a few hundred million years younger.
Does the lunar maria have seas?
In actuality, maria are huge basins containing lava flows marked by craters, ridges, faults, and straight and meandering valleys called rilles and are devoid of water. There are about 20 major areas of this type, most of them—including the largest ones—located on the side of the Moon that always faces Earth.
How old is apollo13?
Apollo 13 launched on April 11, 1970. The Apollo spacecraft was made up of two independent spacecraft joined by a tunnel: orbiter Odyssey, and lander Aquarius. The crew lived in Odyssey on the journey to the moon.
Who is the youngest land on moon?
Charles Duke
Alan Shepard was the oldest person to walk on the Moon, at age 47 years and 80 days. Charles Duke was the youngest, at age 36 years and 201 days.
Are the Moons highlands dark?
From Earth, the lunar highlands appear as light regions while the maria – the lunar plains or “oceans” – appear dark.
