What are the 4 phases of the moon?
The four primary moon phases are:
- New Moon.
- First Quarter.
- Full Moon.
- Third Quarter (Last Quarter)
What happens after a full moon?
After the full moon (maximum illumination), the light continually decreases. So the waning gibbous phase occurs next. Following the third quarter is the waning crescent, which wanes until the light is completely gone — a new moon.
What is the difference between a full and new moon?
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. Full moon occurs when the Moon is on the opposite side of Earth from the Sun, and thus the side…
What are the 5 basic phases of the moon?
There are five phases of the moon: new, crescent, quarter, gibbous and full.
What are the 8 phases of moon?
- New moon. The first phase for us to consider is the ‘new moon’.
- The waxing crescent. The second phase of the Moon is called the ‘waxing crescent’.
- The first quarter.
- The waxing gibbous.
- The full moon.
- The waning gibbous.
- The last quarter.
- The waning crescent.
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.
What are the key features of the moon?
The surface of the Moon has many features, including mountains and valleys, craters, and maria—wide flat areas that look like seas from a distance but are probably solidified molten rock.
What are 5 facts about the moon?
Back to the Moon
- The Moon’s surface is actually dark.
- The Sun and the Moon are not the same size.
- The Moon is drifting away from the Earth.
- The Moon was made when a rock smashed into Earth.
- The Moon makes the Earth move as well as the tides.
- The Moon has quakes too.
- There is water on the Moon!
What surface region of the moon is oldest?
Lunar Highlands rocks returned by Apollo 16 are about 4 billion years old. The oldest Lunar rock found was located by Apollo 17 and appears to be about 4.5 billion years old.
What are the dark areas on 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’. Prof Sara Russell, a planetary scientist at the Museum, works with rock samples and high-resolution images to study the history and geology of the Moon.
Are there canyons on the moon?
Although Saturn’s largest moon, Titan, is surrounded by a thick, hazy atmosphere, Cornell astronomers have revealed that the moon’s terrain features deep, steep-sided canyons filled with liquid hydrocarbons. “The canyons found in Titan’s north are even more surprising, as we have no idea how they formed.
Can you see Grand Canyon from space?
These Canyons are Both Huge; Can You See Them From Space? Yes, both the Grand Canyon and Valles Marineris are visible from space. Astronauts on the International Space Station often take pictures of the Grand Canyon.
What are the canyons on the moon called?
Rille /ˈrɪl/ (German for ‘groove’) is typically used to describe any of the long, narrow depressions in the surface of the Moon that resemble channels. The Latin term is rima, plural rimae. Typically a rille can be up to several kilometers wide and hundreds of kilometers in length.
How deep are canyons on the moon?
The newfound Titan canyons are up to 1,870 feet (570 meters) deep and feature slopes that are at least 40 degrees steep, though they’re fairly narrow, with maximum widths of around 0.5 miles (0.8 kilometers), researchers said.
Which is the deepest trench in Moon?
South Pole–Aitken basin
What is the deepest crater on the Moon?
South Pole-Aitken basin
What does Rille mean?
Rille, any of various valleys or trenches on the surface of the Moon. The term was introduced by early telescopic observers—probably by the German astronomer Johann Schröter about 1800—to denote such lunar features. The word rima (from Latin, “fissure”) is often used for the same kind of features.

What are rays on the moon?
Lunar crater rays are those obvious bright streaks of material that we can see extending radially away from many impact craters. Historically, they were once regarded as salt deposits from evaporated water (early 1900s) and volcanic ash or dust streaks (late 1940s).
How old is a Rille on the Moon?
The Moon’s mountains are even older than the mare, dating back as far as 4.4 billion years. CRATERS – These roughly circular depression in the surface formed when meteoroids struck the Moon at high speeds.
What are the features of the moon named after?
The Moon is remarkable for the variety and unusual nature of the names of its surface features. The dark, smooth maria are named for weather or states of mind (Sea of Rains, Sea of Tranquility) while many of the abundant craters of the Moon are named for famous scientists, philosophers, mathematicians and explorers.
Why do we only see one side of the moon?
One side of the moon always faces Earth because of what’s called synchronous rotation. That is, the moon rotates, or spins on its axis, in the same length of time it takes to orbit Earth. For that reason, our moon always has one side facing Earth, which we call the moon’s near side.
How many craters are on the moon?
9,137 craters
