How were rocks formed on the moon?
A few billion years ago, when the Moon was young and it was hotter than it is now, there was molten rock inside. This lead to the formation of igneous rocks on the surface.
How do rocks on the moon were formed?
Today, virtually all astronomers believe the moon was torn away from earth itself about 4.3 billion years ago, when some other celestial object - a very large one, perhaps as big as Mars - impacted the earth obliquely and tore off a large chunk (earth was still semi-molten at that time). The moon formed from that, and is now held in place by Earth's gravitational pull.
Did Galileo observed craters on the moon?
Yes he did, using the newly invented telescope.
Why was the earth molten at one time?
Yes, in the initial stages after it coalesced into a spherical shape, earth was essentially "molten" for quite some time. It is believed that during this molten period is when earth was struck by another heavenly body about the size of Mars, and the dislodgement of molten material caused by that impact is what formed our moon.
How did the Moon come to be in such an orbit?
In the early days of the solar system about 4.6 billion years ago the Earth had grown from gas particles and asteroid impacts into a molten ball of rock. Fortunately for us (it is thought that life wouldn't have evolved if it wasn't for the moon) a large body probably the size of Mars came along and collided with the newly forming Earth. This added mass to the Earth but also threw off lots of fragments that went into orbit around the Earth. These fragments over millions of years collided and stuck to each other and eventually formed a smaller ball of Rocky magma which when cooled turned into the moon.
What did chemist learn about the mons surface by analyzing moon rocks?
The rocks were similar to rocks formed by volcanoes on Earth, suggesting that vast oceans of molten lava once covered the moon's surface.
What came first the moon or earth?
We're not exactly sure, but it seems most likely that the moon was formed early in the Earth's history, when a large body collided with the Earth, shearing off molten debris. This molten debris formed the Moon. Most research and models show that the moon formed either at the same time or shortly after the Earth.
Is the moon a source of earth's magnetic field?
No. The source of earth's magnetic field is the molten inner core. The moon due to its proximity of course influences our magnetic field but it is to be considered a "weak effect".

What happened to the outer surface of the moon when the moon cooled and a crust formed over the molten interior?
When the moon cooled and a crust formed over its molten interior, the outer surface solidified, leading to the creation of a rugged landscape characterized by impact craters, lava plains, and highlands. As the molten material solidified, volcanic activity contributed to the formation of the Maria, the large basaltic plains visible on the moon's surface. This process resulted in a geologically diverse landscape, while subsequent impacts from meteoroids shaped its current appearance. Over time, the lack of atmosphere and weathering preserved these features, making the moon's surface relatively unchanged for billions of years.
Is Earth's moon made of molten rock?
No. The molten rock which once constituted the moon was long ago solidified from cooling into igneous rock.
In the book New moon what did Bella learn about the newly formed La Push gang?
Bella learns that the newly formed La Push gang are actually werewolves, shapeshifters who transform into wolves to protect their tribe from vampires. She discovers that her friend Jacob Black is part of this group and is now a werewolf.
The name for shapes of the moon seen from earth?
They are called maria. They were formed when asteroid and comet impacts on the moon exposed the mantle of molten rock. The lava flooded into and over the craters and hardened in vast fields forming the dark spots we see when we look up at the moon.
Does the moon have large molten core?
The moon is believed to have a small, solid iron core surrounded by a partially molten outer core. This molten region is thought to be much smaller than that of Earth because the moon is much smaller and has cooled more rapidly. It does not have a large molten core like Earth.
What are the Moon's seas made of?
They are old lava flows from the time when the moon still had a molten core.
