1) What does the term maria refer to?
2) Where does the name maria, meaning sea, come from?
3) How old are they, and what event(s) formed them?
1. Maria are large basaltic plains on our moon, Luna, that have been formed as a result of ancient volcanic eruptions 2. It is a Latin term, where "mare" mean sea. 3. The youngest ones are estimated to be 1.2 billion years old, but most range from around 3-3.5 billion years.
While 2 is not incorrect, I was thinking more along the lines that ancient astronomers thought they were seas on the lunar surface. Otherwise great!OrigamiPlanet wrote:Magikarpmaster629 wrote:Also regarding the moon's maria:

1. Venus 2. Around the sun, 224.7; rotation, 243.02 3. Venus' axis is tilted almost 180 degrees, so it spins on its axis almost exactly opposite its orbit
