The craters on the Moon's maria can vary in size, but some can be several kilometers in diameter. The largest known crater on a lunar mare is the Orientale Basin, which is about 930 kilometers in diameter.

Why do craters contain maria?

Craters don't contain maria. 'Maria' (plural) are the large unbroken expanses that appear smooth, with no craters, or relatively few. 'Maria' means 'seas' ... at one time, they were thought to be oceans on the moon.


Why are there so few craters on the maria?

The maria are the craters. I believe it was Galileo who saw the dark spots on the moon and thought that they were seas, which is why he called them maria ("mar" being Latin for sea). Since then, advancements have been made in astronomy which have shown that the maria are not seas, but craters.

Does the moon surface maria have many craters?

Why are there relatively few craters in the maria of the moon?

The maria on the moon have fewer craters compared to the highlands because they are made of younger, solidified lava flows that have covered and filled in older cratered regions. The volcanic activity that created the maria also played a role in erasing or masking the older impact craters.


What is younger on the moon the maria or the craters?

The maria (large, dark, flat plains formed by ancient volcanic activity) on the moon are younger than the craters (impact sites from asteroids or meteoroids). The maria are estimated to be around 3 billion years old, while many of the craters are thought to be upwards of 4 billion years old.


Does the Highlands on the moon appear to have fewer craters than the maria?

Is it true or false that maria are larger than most craters?

False. Most craters on Earth are larger than Maria, which are large, dark, basaltic plains on the Moon. Craters can range in size from a few meters to hundreds of kilometers in diameter, making them generally larger than Maria.


What are the most obvious features on the Moon's surface?

Craters and the "maria".


Name the three kinds of features that Galileo saw on the Moon's surface?

Craters. Mountainous areas. Also, the dark areas called "maria" are very prominent, mainly on the side of the Moon facing Earth. The whole surface is covered in broken rock and dust. That's why astronauts left footprints.
