He thought it was covered in seas because of the craters on the moon.
many craters, mountains, and what Galileo referred to as 'seas'.
There are no seas on the moon. The moon's surface is mostly covered by craters, mountains, and plains, but no bodies of water like seas or oceans. The dark areas on the moon that look smooth from Earth are actually large plains of solidified lava called maria.
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.
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.
Maria, or the dark plains on the Moon, were once believed by Galileo to be vast oceans or seas. He referred to these features as "maria," the Latin word for "seas," based on their appearance through his telescope. Galileo's observations in the early 17th century contributed to the misconception that the Moon had large bodies of water, rather than being dry, solid surfaces. This misunderstanding persisted until further lunar exploration revealed the true nature of these plains.
There are no seas on the Moon, but it was believed that there were.
Galileo mistakenly believed that the maria, or dark plains on the Moon's surface, were large bodies of water, similar to seas on Earth. He referred to them as "seas" due to their appearance and the limitations of his observational tools. This misinterpretation was a result of the lack of detailed knowledge about the Moon's geology and surface composition at the time. Modern science has since clarified that the maria are actually vast basaltic plains formed by ancient volcanic activity.
It is covered by 90% of seas and oceans.:)
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.
The seas on the moon are not like earth's seas. They do not contain water and are the same grey color as the rest of the moon.
Galileo used the Latin word 'Maria' to describe the vast lakes of hardened lava he saw on the moon because 'Maria' means 'seas' in Latin. Although these features are not actual bodies of water, they resemble the appearance of large, dark, smooth plains or seas when observed from Earth.
astronauts thought the moon was flat ,so they called some areas,seas.
