RILLE. One of certain narrow, crooked valleys seen, by aid of the telescope, on the surface of the moon..
In this regard, what are valleys on the moon called?
Sinuous rilles are probably the most recognizable of small volcanic features on the Moon. Many partially resemble river valleys on the Earth. Thus, the sinuous rilles probably mark lava channels or collapsed lava tubes that formed during mare volcanism.
Furthermore, how are valleys formed on the moon? Valleys. Valleys are unusual because other features such as craters or rays (ejecta from impacts) intersect them. They are thought to have formed by ancient lava flows, collapsed lava tubes or geological faults. They are sometimes labelled as rilles - cracks or clefts on the lunar surface notably near maria.
Considering this, what are lunar rays?
Lunar rays are filamentous, high-albedo deposits occurring radial or subradial to impact craters. The nature and origin of lunar rays have long been the subjects of major controversies.
What are the three main features of 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.
Related Question Answers
Is there water on the Moon?
Lunar water is water that is present on the Moon. Liquid water cannot persist at the Moon's surface, and water vapor is decomposed by sunlight, with hydrogen quickly lost to outer space.Does the moon have mountain ranges?
The moon has neither tectonic plates nor volcanic action. Virtually all of its mountains are the result of impacts by asteroids in the distant past. The mountain ranges and individual mountains are labeled with their Latin names, "montes" for mountain ranges and "mons" for individual mountains.Are there footprints on the moon?
An astronaut's footprint can last a million years on the surface of the moon. It may have been decades since we last set foot on the moon, but its surface is still marked with the historic footprints of the 12 astronauts who stomped across it. That's because the moon has no atmosphere.Does the moon have a core?
Deep inside of its interior, the moon may have a solid iron core surrounded by a softer, somewhat molten liquid iron outer core. The outer core may extend as far out as 310 miles (500 km). But the small inner core only makes up about 20 percent of the moon, compared to the 50 percent core of other rocky bodies.How many seas are on the moon?
It also includes the one oceanus and the features known by the names lacus, palus and sinus. The modern system of
lunar nomenclature was introduced in 1651 by Giovanni Battista Riccioli.

Is the moon a desert?
The Moon is like a desert with plains, mountains, and valleys. It also has many craters, which are holes created when space objects hit the Moon's surface at a high speed. There is no air to breathe on the Moon. The Moon is much smaller than the Earth.What is the temperature of the moon?
Daytime on one side of the moon lasts about 13 and a half days, followed by 13 and a half nights of darkness. When sunlight hits the moon's surface, the temperature can reach 260 degrees Fahrenheit (127 degrees Celsius). When the sun goes down, temperatures can dip to minus 280 F (minus 173 C).What is the tallest mountain on the moon?
Mons Huygens
Why does the moon have lines?
The reddish-brown lines that crisscross the icy surface of Jupiter's moon Europa may be radiation-bombarded sea salt from an underground ocean, a new study suggests.What is a maria on the moon?
The lunar maria /ˈm?ːri?/ (singular: mare /ˈm?ːre?/) 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.Do all craters have rays?
Typically, visible rays have a higher albedo than the surrounding surface. More rarely an impact will excavate low albedo material, for example basaltic-lava deposits on the lunar maria. Rays can also become covered by lava flows, or by other impact craters or ejecta.What is a crater on the moon?
Lunar Craters Craters on the Moon are caused by asteroids and meteorites colliding with the lunar surface. The Moon's surface is covered with thousands of craters. Why does the Moon have so many craters compared to the Earth? Unlike the Earth, the Moon has no atmosphere to protect itself from impacting bodies.What is the origin of the bright rays that radiate outward from Copernicus?
Perhaps much of the continuous ejecta blanket is also formed of material splashed out by secondary impacts. Bright rays of ejecta radiate outward from Copernicus across a large part of the Moon's near side.How old are the craters on the moon?
two billion years
What are the dark spots on the moon?
And it's light in another sense, too: The "dark" side has few of the distinctive dark spots that mark the Earth-facing side of the moon. Those spots are called maria, from the Latin word for sea, because early astronomers mistakenly thought they were lunar seas (they're actually volcanic plains).Does the moon rotate?
The moon orbits the Earth once every 27.322 days. It also takes approximately 27 days for the moon to rotate once on its axis. As a result, the moon does not seem to be spinning but appears to observers from Earth to be keeping almost perfectly still. Scientists call this synchronous rotation.Does the moon have clouds?
The Kordylewski clouds are located near the L4 and L5 Lagrange points of the Earth–Moon system. They are about 6 degrees in angular diameter. The clouds can drift up to 6 to 10 degrees from those points.Why is the moon Rocky?
Surface composition Like the four inner planets, the moon is rocky. It's pockmarked with craters formed by asteroid impacts millions of years ago. Because there is no weather, the craters have not eroded.How does the moon stabilize the earth climate?
The Moon keeps the Earth from wobbling violently as it spins. “Without the Moon the tilt of the Earth's axis would vary more, with potentially strong climatic effects,” says Aksnes. With no moon as a stabilizer, the Earth would sometimes tilt all the way over and lie on its side in relation to its orbit around the Sun.
