What is the difference between the condensation theory and the Nebular Theory?
Condensation Theory: An extension of Nebular Theory that incorporates interstellar dust as a key ingredient. The solar nebula is initially a thin gas of hydrogen and helium strewn with tiny dust particles. These grains act as condensation nuclei, on which accretion of matter occurs.
What is the condensation theory?
The Condensation Theory: This theory proposes that the Moon and the Earth condensed individually from the nebula that formed the solar system, with the Moon formed in orbit around the Earth. However, if the Moon formed in the vicinity of the Earth it should have nearly the same composition.
What does the Nebular Theory explain?
The nebular hypothesis is the idea that a spinning cloud of dust made of mostly light elements, called a nebula, flattened into a protoplanetary disk, and became a solar system consisting of a star with orbiting planets [12].
What is the difference between condensation and accretion?
Condensation is the building of larger particles one atom (or molecule) at a time, whereas accretion is the sticking together of larger particles. The planets swept up gas, dust, and small particles.
How does the condensation sequence theory explain the similarities and differences between Jovian and terrestrial planets?
The condensation theory can explain the basic differences between the jovian and terrestrial planets because the temperature of the solar nebula would be expected to decrease with increasing distance from the Sun. When the Sun became a star, its strong winds blew away any remaining gas in the solar nebula.
What is the difference between a nebula and a solar nebula?
Nebula is a large cloud of gas and dust in interstellar space. Solar nebula is a rotating cloud of gas and dust from which the sun and planets formed.
Why is the solar nebula theory considered a theory rather than a hypothesis?
Why is the solar nebula theory considered a theory rather than a hypothesis? It has extensive evidence and explains many observations of different objects.
