Which hypothesis states that the moon originally broke away from Earth during its early formation?
PolarNik [594]

the answer D. Giant impact hypothesis or large impact hypothesis

The origin of the Moon refers to several explanations regarding the formation process of the Moon, Earth's natural satellite. Theory The large collision hypothesis is the best-known theory regarding the origin of the moon.

<h2>Further explanation </h2>

The big collision hypothesis theory states that the Moon was formed from debris left over from a collision between Earth and an object the size of the planet Mars, about 4.5 billion years ago. The object that crashed into the Earth is often called Theia taken from the Greek Titan myth, which is the mother of Selene, the goddess of the Moon.

Other hypotheses about the origin of the moon:

  • Catching Hypothesis. This hypothesis says that the Moon is an object captured by the Earth.
  • Cleavage Hypothesis. This hypothesis says, in the old days, the Earth was spinning very quickly throwing some of its mass.
  • Accretion Hypothesis. This hypothesis says that the Earth and the Moon formed at the same time as a double system of ancient accretion disks in the Solar System.
  • The Georeactor Explosion Hypothesis. Another more radical hypothesis was published in 2010, saying that the Moon might have been created by a georeactor explosion located along the boundary of the mantle's core in the rapidly rotating equatorial plane of the Earth. This hypothesis can explain the similarity of the composition of the Earth and the Moon.

Compare and contrast the function and structure of a compound light micrscope and electron micscrope
galben [10]
The major difference between a light microscope and a electron microscope would be that with the light microscope, a beam of light is used to focus the image. In an electron microscope, a beam of electrons is used to focus the image. Other notable differences would be with the light microscope, your specimens must be very thin; thin enough for light to pass through them. With the EM, you can place whole specimens that can generate 3D images. There is a much more complex specimen preparation process for the EM, where light microscope slide making is fairly simple in comparison. You can view live and wet specimens with a light microscope but you cannot with the EM because an EM requires specimens to be placed in a vacuum chamber. Lastly, the EM is very large and complex to operate, where the light microscope is somewhat portable. Hope this helps!
