Moon Formation Research Paper

In 1975, two scientists by the name of Dr. William K. Hartmann and Dr. Donald R. Davis, came up with a groundbreaking new theory on how the moon was created. Their theory stated “At the time Earth formed 4.5 billion years ago, other smaller planetary bodies were also growing. One of these hit earth late in Earth 's growth process, blowing out rocky debris. A fraction of that debris went into orbit around the Earth and aggregated into the moon” (Hartmann & Herres 1). This theory is known as the Giant Impact Theory and is the accepted theory in the scientific community of how the moon was created. Even though this theory is accepted by most, there are still some people who don’t hold this theory to be true. I agree with Davis and Hartmann’s Giant Impact Theory that a great collision occurred and created the moon. The Giant Impact Theory is supported by the lack of iron on the moon, the moon rocks from the Apollo missions, and its acceptance in the scientific community.

It has been known for well over a century now that the Earth’s core, mantle and the crust make up the basic structure of the Earth. However, there is some controversy over how and when the Earth produced its core, mantle and crust. In this essay, I will first discuss about the formation of the Early Earth and its Moon, then about the methods used to pinpoint the age of the Earth. Other than that, I will also expand on core and mantle formation, as well as the eventual production of the continental crust.

The meteor that caused the crater would have been at least 6 miles wide, also entering the atmosphere at 45,000 Mph will burn so bright that bodies would be rendered invisible to the bone and when entering the denser atmosphere the rock would have evaporated into pulsar. A Meteor that size would have cause endless earthquakes and the made 300-400 feet high tsunami destroying the coast and also filling the air with superheated dust and smoke around 600 Degrees Fahrenheit spreading around the world covering it in a thick blanket, The Earth is like an oven the crust is being baked and all the dinosaurs on it without

The most favoured theory on the genesis of the moon that serves as a satellite to the Earth is the Theia Impact Hypothesis. When the early solar system was forming in the first 100 million years after the dust cloud began to coalesce, along with the recognized planet that survived until today, there were other proto-planets forming and orbiting our common star, the sun. Many of these proto-planets were ejected from the solar system, or else crashed into larger proto-planets, either destroying both in the process, or melding into one larger proto-planet. One of these theorized proto-planets was a Mars sized rocky body, known as Theia, which shared the Earth's orbital path.

The exact origins of the moon are unknown however there are many plausible theories. The most widely accepted theory is known as the giant impact hypothesis. This suggests that the moon was created during a collision between a young Earth and a Mars sized object over four billion years ago. As the two bodies collided they fused whilst simultaneously ejecting debris which combined and formed the moon as we know it.

Despite the theory of how the moon was formed from a single impact with Earth, samples taken from the moon and lunar meteorites have illustrated that the Earth and the Moon possess compositions that are fairly analogous. Also another contradicting piece is that there are some issues in honing the impact to give it the same angular momentum of Earth’s specific moon system. Though there are solutions to both these contradictions, neither answers every question. For example, one can theorize that the impactor itself had a similar make-up to Earth’s, but that itself is statically unlikely. For the second hypothesis, some scientists have argued that this process would have taken a long time and that this contradicts a few theories on when the moon was formed. New research this year (January 11th 2017 in Science Advances to be exact) helps build on the idea that the moon came together at a faster pace and formed about 4.51 billion years ago. Aside from when and how the moon was formed, findings suggest that water may have been in abundance on the moon during its formation and played a key part in how it was

The “giant-impact hypothesis” explains the creating of the moon by a collision of the Earth by a large size rock named Theia. In the past, scientist explained that the rock Theia collided at an angle towards earth and vaporized Theia completely and part of Earth. The debris then came back on Earth and some debris orbited Earth creating the moon. Samples of rock from the Moon are identical from Earth that gives evidence to this theory. Over the past 15 years, more evidence suggested that the rock Theia made a high-energy impact that decimated both Theia and most of Earth, the dense vaper than formed an atmosphere that filled a space than 500 times bigger that today’s Earth. Some debris than collided back to Earth and some formed the Moon. Scientist

The Moon has been around for 4.5 billion years. “The leading explanation for how the moon formed was that a giant impact knocked off the raw ingredients for the moon off the primitive molten Earth and into orbit” (Choi, 2017) about 95 million years after our solar system was born. This collision is thought to had been between a Mars size like object and earth. Back then Earth was a ball of molten magma. Once the object crashed with earth, the object collected magma and it was sent into orbit by the collision. After 100 million years all that magma in the object was able to crystallize and form the Lunar crust. With time it crystallized more and more giving us our beautiful moon as the only natural satellite of our home Earth.

There are many astrologers in the world , but some astrologers don’t really know how the moon’s mysterious craters suddenly appeared all over the moon. So I thought “hey” “I should help out these astronomers who don’t really know who the moon’s craters were actually created” so I decided to help out these astronomers , by creating my own project which surface would be best for craters? Some astrologers say the moon’s surface has many types of material. But I will be testing out which one would be best or the the surface that looks like a moon! I am going to use a rubber and sponge ball to reenact as asteroids that are going to hit the moon from billions of years ago. To start the investigation we first need to find out how high we will drop the ball , we will drop it around my height , so about 5 feet 7 inches then we will continuously be dropping the ball in the 4 different type of surfaces such as gravel (small rocks) , flour , soil, dirt, and we will be dropping the ball five times from the same height for each surface and we’ll go on from there . And some important vocabulary words for this experiment are Astronomy, Asteroids, Gravity Diameter , height , sponge ball , rubber ball , craters , and yes it is a lot of words but guess what? It’s all worth it at the end you all are really going to enjoy this project , I guarantee it. If you don't like you'll get your money

asteroids hitting the Earth, we might not be here today. Millions of years ago when the Earth

The night of observing, the Moon was in the waxing gibbous phase. The Moon was formed when it collided with Earth as a planetesimal and now it is an object that orbits Earth. The distance from Earth to the Moon is 238,855 miles away and is about 4.5 billion years old. (How) That night at 8:15 pm the telescope was places so we could see were the Moon was illuminated and where it was dark. On the left side of the Moon their were some darker spots, were greyish in color, compared to the reset of the Moon. Even though it was partly cloudy with slight wind that night we could see the craters on the Moon clearly. Through the telescope I saw craters with a typical bowel shape and others with more complex. Another type of crater I saw was

Next to the Sun, the moon is the most recognizable object in the night sky, and is Earth’s only natural satellite. It has been estimated that the moon formed somewhere in the region of 4.45 billion years ago, just a measly 30-50 million years after the origination of the Solar System. While there are many hypotheses that try to account for the formation of the moon, the one that is backed the greatest is the theory that the moon was formed when a large mass roughly the size of Mars collided with the newly formed Earth, this sending out planetary material into the same orbit of the Earth. This material then underwent the process of accretion and formed what we now know as the moon.

Complex alterations of the lunar surface occur, despite the fact that lunar processes are much less varied and dynamic than those of the Earth. The most important source of lunar surface alteration, at least over the last three billion years, is evidenced by the Moon’s heavily pocked and cratered surface.

The Earth and Moon do have some similarities and differences that are explained by this theory. The Moon, for example, does not have heavy materials like Earth does. One example of a heavy material on Earth is the iron core. Earth has one, and the Moon does not. This is explained by the timing of the impact. If the Moon hit the
