What are the 5 characteristics of a moon?
Characteristics of the Moon include its distance from the Earth, size, mass, density, and temperature.
What are the Moon’s regions?
The lunar surface can be divided into two main regions, the highlands and the maria. The highlands make up roughly 83 percent of the moon’s surface, whereas the maria make up about 17 percent of its surface. Both of these regions have a characteristic density of craters from meteor impacts.
Which 3 characteristics describe conditions on the Moon?
The moon has no atmosphere, no weather and no oceans of water. Its surface is in a perpetual vacuum. Pairs of astronauts have lived on its surface only up to three days at a time, in the tiny Lunar Module of the Apollo program.
What are the characteristics of the topography of the Moon?
Answer. Answer: One of the surprising parts of lunar topography is that the crust on the far side of the Moon is much higher than on the near side. The near side of the Moon has large, low-lying, relatively smooth plains of basalt rock, which are shown as bluish-green features.
What are 2 characteristics of the Moon?
It is a spherical rocky body, probably with a small metallic core, revolving around Earth in a slightly eccentric orbit at a mean distance of about 384,000 km (238,600 miles). Its equatorial radius is 1,738 km (1,080 miles).
What are the 4 major features of the Moon’s surface?
The moon’s surface is covered with dead volcanoes, impact craters, and lava flows, some visible to the unaided stargazer. Early scientists thought the dark stretches of the moon might be oceans, and so named such features mare, which is Latin for “seas” (maria when there are more than one).
What is the dark region of the Moon called?
The surface of the Moon is covered in huge dark spots, visible from Earth even with the naked eye. These patches are known as maria – a Latin word meaning ‘seas’.
What are the dark regions of the Moon?
When you look at the Moon, you will see dark and light areas. The dark areas are young plains called maria and are composed of basalt. The basalt flowed in and flooded the area created by a huge impact with an asteroid or comet.
What are two types of rock regions found on the Moon?
The two most common kinds are basalts and anorthosites. 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.
What are the characteristics and phases of the Moon?
The Moon displays eight phases: new, waxing crescent, first quarter, waxing gibbous, full, waning gibbous, last quarter, and waning crescent. New moon occurs when the Moon is between Earth and the Sun, and thus the side of the Moon that is in shadow faces Earth.
What are the major features of the Moon explain long answer?
The moon does not have heat and light of its own. The moon shines because it reflects sunlight. There is no atmosphere around it and no trace of water. Due to the absence of an atmosphere, there is a great difference between the day (127°C) and night (-173°C), and no weather, clouds, rain, or winds exist.
What is the Moon environment like?
On the moon, there’s no air to breathe, no breezes to make the flags planted there by the Apollo astronauts flutter. However, there is a very, very thin layer of gases on the lunar surface that can almost be called an atmosphere. Technically, it’s considered an exosphere.

What is the best known feature of the moons surface?
If you look at the Moon through a telescope, you can see that it is covered by impact craters of all sizes. The most conspicuous of the Moon’s surface features—those that can be seen with the unaided eye and that make up the feature often called “the man in the Moon”—are vast splotches of darker lava flows.
How many features does the Moon have?
The Moon has plains, mountains, valleys, an estimated 300,000 lunar craters, as well as rilles, lava domes, and other stunning features.
What are the light regions of the Moon called?
It is divided into light areas called the Lunar Highlands and darker areas called Maria (literally, “seas”; the singular is Mare).
Will it rain in Moon?
The moon has a very thin atmosphere so it cannot trap heat or insulate the surface. There is no wind there, no clouds, no rain, no snow and no storms, but there is “day and night” and there are extreme differences in temperatures depending on where the sun is shining.
Is there water on the Moon?
Recent unmanned missions to the moon have discovered a few remnants of water ice trapped in sheltered craters around the poles, but much of the moon’s surface is now dry.
What are the light and dark areas of the Moon called?
Maria
The near side of the moon has light areas referred to as Lunar Highlands and dark areas called Maria. The maria are lower in altitude than the highlands and filled with dark solidified lava from when the moon was volcanically active.
Why is it silent on the Moon?
However, the Moon is in space, and space is mostly a vacuum (there are always some atoms floating around, but they are VERY far apart and don’t interact with one another). Thus there is no sound on the Moon.
