Also regarding the moon's maria:

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!

Let's try something other than maria for now:

1) Identify the astronomical body.
2) How long, in Earth days, does it take this body to make an entire revolution?
3) Give a theory as to why the body moves in a retrograde rotation.

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

1. Name this formation.
2. How did it form?
3. Name a terrestrial body that has these formations.
