The dominant scientific model is that the Earth and all the planets (and the Sun) coalesced from a molecular cloud, also known as a nebula.
Supernovae are the only known natural events capable of producing elements heavier than Iron, and since heavy elements exist on Earth (and in the Sun), the debris field must have come from a supernova.
Clouds of gas and debris which exist in space have centers of gravity which cause the debris field to collapse toward a central point. This process is known as planetary accretion. As the gravity pulls material in and bits of mass collapse, angular momentum is conserved and primary rotation(s) begin. The solar system as well as the planets all rotate due to conservation of angular momentum around various gravitational centers.
Of course there are other "theories," or beliefs regarding the creation of the Earth, but these are not based on scientific evidence. Many people believe the Earth was created instantaneously, out of nothing, by a deity.

What would be a correct statement regarding metamorphic rock formation?
the deeper into earth crust the higher the pressure that forms metamorphic rocks
Who invented the world?
The concept of the world as we know it was not invented by any one person. The world's existence and formation is attributed to natural processes and scientific theories such as the Big Bang theory for the creation of the universe and Earth's formation over billions of years.
Which is the correct order in this secuence of events Big Ban Formation of galaxies formation of sun formation of earth?
Big Bang, formation of galaxies, formation of sun, formation of earth.
According to Copernicus what planet are located between the sun and the earth?
All the theories have Mercury and Venus between the Earth and the Sun.
What is theories of changes in the lithosphere?
The lithosphere undergoes changes through processes like plate tectonics, which describe the movement of Earth's outer shell. This movement results in phenomena such as earthquakes, volcanic eruptions, and the formation of mountains. Understanding these changes helps scientists predict natural disasters and study the evolution of Earth's surface over time.
What are the different earth theories?
Do you mean the formation of the Earth? If so, the two competing theories are creation and evolution, as in the formation of the observable universe by the Big Bang.

What are the different theories regarding the shape of the earth?
The main theories regarding the shape of the Earth are the oblate spheroid theory, which posits the Earth is mostly spherical but slightly flattened at the poles due to its rotation; the geoid theory, which describes the Earth as an irregular shape that approximates global mean sea level; and the flat Earth theory, a debunked belief that the Earth is flat and not a sphere.
Which answer is not one of the three theories of the Moon formation?
There are three main theories of how the moon came into existence. The theories are as follows: the moon was captured by Earth's gravitational pull, the moon was originally part of the earth's crust, or the earth and moon formed together out of the primordial nebula.
Who is the scientist formulated the different theories regarding the history of the earth?
You may be talking about Charles Darwin . . .
What is one of the accepted theories of the formation of the moon?
An early collision by (proto) Earth with a large protoplanet..
What are some common theories about the Moon's formation?
That is was a captured asteroid, it broke away from the earth after a huge impact, that it formed at the same time as the earth.
Can why the earth was formed be answered by scientists?
Yes, scientists have proposed theories to explain the formation of Earth. One widely accepted theory is that the Earth formed from accretion of dust and gas in the early solar system, approximately 4.5 billion years ago. This process led to the formation of rocky planets like Earth.
What would be a correct statement regarding metamorphic rock formation?
the deeper into earth crust the higher the pressure that forms metamorphic rocks
Explain how erupting volcanoes contributed to the formation of oceans?
Some theories regarding the origin of Earth's water say that it was "in" the Earth since it formed and that Volcanoes have brought it to the surface over geologic time. However, recent scientific work using the isotopic composition of Earth's water point to it having been delivered to Earth by meteorites and comets after the Earth was formed. This said, volcanoes are certainly part of Earth's current water cycle as areas of hot springs and mid oceanic, black smokers prove.
Has Earth always had the same composition?
The theories of planetary formation indicate that Earth's original form had more hydrogen and helium and less of the current atmospheric nitrogen and oxygen. Water may have been added by comets that Earth swept from its solar orbit.
What are the different scientific theories develop by the scientist to explain the origin of the earth?
Some scientific theories explaining the origin of Earth include the nebular hypothesis, which suggests that the solar system formed from a rotating disk of gas and dust, and the giant impact hypothesis, which proposes that the Moon formed from debris created by a collision between Earth and a Mars-sized protoplanet. Other theories include the core accretion model for planet formation and the theory of planetary migration.
