How would the surface of the Moon different today if meteorites had continued to hit it at the same rate as they did 3 billion years ago?
Describe how the surface of the moon would be different today if meteorites had continued to hit it at the same rate as they did 3 billion years ago. Many more craters would have been produced and the layer of debris would be much thicker.
How were the maria of the Moon formed quizlet?
How did the lunar maria form? the lava cooled, it formed the maria. The moon would probably have many more impact craters on its surface. Many of the impact craters on the near side are covered by maria, but the maria are no longer forming.
What do scientists believe about the maria regions of the Moon’s surface?
Maria are the large, smooth, dark areas of the Moon’s surface. This is a Latin word for “seas” (think of mare). These regions, like most of the Moon, are devoid of water. Interesting fact: Ancient observers would look onto the moon and would imagine the dark patches as oceans.
What is a mare on the Moon quizlet?
what is a mare on the Moon? large area of darker material on the lunar surface. maria are. ancient lava floodplains.
What happened to Earth’s twin Theia?
Scientists have long agreed on the existence of the planet, called Theia, and its role in creating the moon. The theory goes that Theia crashed into Earth early in its life and knocked loose a chunk of rock that would later become the moon.
Where is Theia now?
Scientists have long agreed that the Moon formed when a protoplanet, called Theia, struck Earth in its infancy some 4.5 billion years ago. Now, a team of scientists has a provocative new proposal: Theia’s remains can be found in two continent-size layers of rock buried deep in Earth’s mantle.
What caused the maria to form?
The maria basins were formed beginning about 3.9 billion years ago during a period of intense bombardment by asteroid-sized bodies. This was well after the lunar crust had cooled and solidified enough, following the Moon’s formation, to retain large impact scars.
What forms maria on the Moon Group of answer choices?
The lunar maria /ˈmɑːriə/ (singular: mare /ˈmɑːreɪ/) are large, dark, basaltic plains on Earth’s Moon, formed by ancient volcanic eruptions. They were dubbed maria, Latin for “seas”, by early astronomers who mistook them for actual seas.
What surface region of the Moon is oldest?
Lunar Highlands
Lunar Highlands rocks returned by Apollo 16 are about 4 billion years old. The oldest Lunar rock found was located by Apollo 17 and appears to be about 4.5 billion years old.

What is a sea on the moon?
Despite their name, the lunar seas are plains of solidified lava which appear dark on the Moon’s disc. Many lunar seas are large enough to spot with just your eyes, so see how many you can locate for our first challenge sheet.
What makes the Maria landforms on the Moon?
“Maria” is Latin for “seas” (the singular is “mare”). However, the maria do not contain water. Instead, they are the remnants of lava flows on the moon’s surface. The lava flowed through cracks in the moon’s crust and cooled on its surface.
How did Maria on the Moon get its name?
Describe what maria on the surface of the moon look like and how they came to be known as maria? Maria are large, dark, basaltic plains on the moon. Galileo named these places ‘maria’ after the Latin word for sea because he thought they looked like oceans.
Which is older the lunar highlands or Maria?
About 85% of the Moon’s surface is covered by lunar highlands. The lunar highlands have more craters, so they are older than maria. The side of the Moon that faces away from the Earth, often called “the dark side of the Moon,” is mainly covered with lunar highlands. This may mean that the crust on this side is thicker.
Why are there no Maria on The Dark Side of the Moon?
The side of the Moon that faces away from the Earth, often called “the dark side of the Moon,” is mainly covered with lunar highlands. This may mean that the crust on this side is thicker. If this is so, this may explain why there are no maria on this side of the Moon.
