He thought they were seas. He called them maria (Latin for sea). Today scientists still call the dark, flat parts maria. Marias were formed when magma flowed through the surface of the moon. The magma cooled and became flat and dark.
that the moon was not flat, it was a sphere.
People had known the earth was not flat for centuries before Galileo's birth - much navigational technology had all based on that fact, and would not have worked otherwise. Galileo is more well known for providing observations and evidence that the sun, not the Earth, was the centre of the solar system - however the main proponent of this fact was Copernicus, a century previously.
The most usual term for large, flat areas is plains.
Galileo discovered the four largest moons of Jupiter (later named the Galilean moons), mountains and craters on the moon, phases of Venus, and sunspots on the sun. These observations supported the heliocentric model of the solar system and challenged the geocentric view of the universe.
My friends and me call them 'cheesies' because they are cheese shaped.
Galileo called the dark flat parts on the moon "seas" or "maria" in Latin, although they are now known to be basaltic plains formed by ancient volcanic activity.
When Galileo looked through his telescope at the moon, he saw dark, flat parts of the moon's surface which he called maria.
A "Maria", which is translated into "sea".

Luna's (Earth's moon's) apparent dark spots are giant "dust puddles." They are areas with large collections of dry sediment. Such things are best avoided, since they can be very deep, and therefor deadly.
flat worms live in Streams,Shallow Parts Of Lakes,Dark Places,On the surface of rocks and plants and also they live in moist soilhope it helped :)
craters
The dark areas that form the 'man in the moon' are large flat plains called maria and the brighter parts of the moon are the lunar highlands and the mountain ranges.
A "Layer" is a flat covering or thickness
Other than being slightly flattened at the poles, no parts of the world are perfectly flat. We perceive the ground we stand on as being flat rather than curved, though.
