A small body moving in the solar system that would become a meteor if it entered the earth's atmosphere.
What are the five major stages of planetary formation?
The birth of a star, the evaporation of the gas cloud, the formation of bolides, the creation of gas and dust to form small bodies between 1-10 km in diameter, and less violent and rapid impact accretion.
The gravitational collapse of a star, the condensation of the gas cloud, the formation of chondrules, the accretion of gas and dust to form small bodies between 1-10 km in diameter, and more violent and rapid impact accretion.
The gravitational collapse of a white dwarf, the condensation of the gas cloud, the formation of chondrules, the accretion of gas and dust to form small bodies between 2,000,000 km in diameter, and more violent and rapid impact accretion.
The gravitational collapse of a star, the condensation of the gas cloud, the formation of the Avengers, the accretion of gas and dust to form small bodies between 1-10 km in diameter, and the birth of Groot from more violent and rapid impact accretion.
Why are the terrestrial planets found closer to the sun
that the Jovian planets?
The terrestrial planets formed close to the Sun where temperatures were well suited for rock and metal to condense. The Jovian planets formed outside what is called the frost line, where temperatures were low enough for ice condensation.
The terrestrial planets formed close to the Sun where temperatures were not well suited for gas and water to condense. The Jovian planets formed outside what is called the frost line, where temperatures were low enough for ice condensation.
The terrestrial planets formed close to the Sun where temperatures were well suited for rock and metal to condense. The Jovian planets formed inside what is called the yard line, where temperatures were low enough for ice condensation.
I am Groot.
Which explains CORRECTLY how old the Earth is estimated to be and the chemicals that make up our planet?
The Earth is 1 billion years old. Except for hydrogen and some helium created in the Big Bang. This occurred through sustained fusion or in supernova explosions.
The Earth is 8 billion years old. Except for hydrogen and some helium created in the Big Bang. This occurred through sustained fusion or in supernova explosions.
The Earth is 4.54 billion years old. Except for hydrogen and some helium created in the Big Bang. This occurred through sustained fission or in supernova explosions.
The Earth is 4.54 billion years old. Except for hydrogen and some helium created in the Big Bang, all of the stuff we and the Earth around us are made of was generated in stars. This occurred through sustained fusion or in supernova explosions.
Where does the Earth's magnet field come from?
Earth's magnetic field is the magnetic field that extends from the Earth's interior out into space, where it interacts with the solar wind. It is generated buy the Earth's core of solid iron.
Earth's magnetic field is the magnetic field that extends from the Earth's interior out into space, where it interacts with the solar wind. It is generated buy the Earth's core of molten copper.
Earth's magnetic field is the magnetic field that extends from the Earth's interior out into space, where it interacts with the solar wind. It is generated buy the Earth's core of molten iron.
Earth's magnetic field is the magnetic field that extends from the Earth's interior out into space, where it interacts with the solar wind. It is generated buy the Tesseract that is buried deep within it.
Where did the Earth's moon come from?
It came from a fiery crash. The most popular scientific theory for the origin of the moon is that two large planetesimals, Thea and Earth, collided in the solar nebula.
It came from a fiery crash. The most popular scientific theory for the origin of the moon is that two large planetesimals, Mars and Earth, collided in the solar nebula.
It came from a fiery crash. The most popular scientific theory for the origin of the moon is that two large planetesimals, Venus and Mercury, collided in the solar nebula.
The origin of the moon is that two large planetesimals collided in the solar nebula thereby cutting Tony Stark off from Earth and leaving the formation process in the capable hands of Thanos who held the Infinity stones.
Which is a reasonable explanation for all of the water found on our planet?
The blue infinity stone found on Thanos's glove represented water, therefore it became abundant in our solar nebula and planetary accretion disk when he snapped his fingers.
The conspicuous amount of water found on Earth is proof that water was abundant in our solar nebula and planetary accretion disk. It could be found in the matter and rocky materials that were creating our planetesimal.
The conspicuous amount of water found on the Moon is proof that water was abundant in our solar nebula and planetary accretion disk. It could also be found in the matter and rocky materials that were colliding to create our planetesimal.
The lack of water found on Earth is proof that water was not abundant in our solar nebula and planetary accretion disk. It could not be found in the matter and rocky materials that were colliding to create our planetesimal.
