Question: According To Modern Science, What Was The Approximate Chemical Composition Of The Solar Nebula?

What was the composition of the solar nebula?

The solar nebula, like most things in the universe, was 98% Hydrogen and Helium, with small amounts of hydrogen compounds (1.4%) and traces of rock and heavy metals (0.6%). All elements heavier than Iron were created in supernova explosions of prior high-mass stars.

Which of the following lists the major ingredients of the solar nebula?

According to our present theory of solar system formation, which of the following lists the major ingredients of the solar nebula in order from the most abundant to the least abundant? hydrogen and helium gas; hydrogen compounds; rock; metal.

What is the primary basis on which we divide the ingredients of the solar nebula into the four categories hydrogen helium hydrogen compounds rock and metal?

What is the primary basis upon which we divide the ingredients of the solar nebula into four categories (hydrogen/helium; hydrogen compound; rock; metal)? – The atomic mass numbers of various materials. – The amounts of energy required to ionize various materials.

What are the four major ingredients that make up the solar nebula?

The ingredients of the solar nebula fell into 4 categories based on their condensation temperatures: metals, rocks, hydrogen compounds (water, methane, ammonia), and light gasses (hydrogen and helium). Distance of a planet from the Sun determined the temperature and thus the materials which condensed first.

What does the solar nebula theory explain?

Solar nebula, gaseous cloud from which, in the so-called nebular hypothesis of the origin of the solar system, the Sun and planets formed by condensation. Swedish philosopher Emanuel Swedenborg in 1734 proposed that the planets formed out of a nebular crust that had surrounded the Sun and then broken apart.

What were the three major components of the solar nebula?

The solar nebula is the cloud of gas from which our solar system was born when it collapsed under its own gravity. By using the compositions of the Sun, other stars, and interstellar gas clouds, we know that the solar nebula contained 98% hydrogen and helium and only 2% of all other elements combined.

What is Pluto classified according to our theory of solar system formation?

According to our theory of solar system formation, what is Pluto? D) Pluto is a large Kuiper-belt comet. Based on our current theory of Earth’s formation, the water we drink comes from. A) ice that condensed in the solar nebula in the region where Earth formed.

What changed as the solar nebula shrank?

They were produced by stars that lived and died before our solar system was born. According to our theory of solar system formation, what three major changes occurred in the solar nebula as it shrank in size? It got hotter, its rate of rotation increased, and it flattened into a disk.

Which lists the major steps of solar system formation in the correct order?

Hydrogen and Helium. Which lists the major steps of solar system formation in the correct order? Collapse, Condensation, Accretion.

Which Jovian planets in our solar system have rings?

All four Jovian planets have rings: Jupiter, Saturn, Uranus, and Neptune. These rings are made up of rock, dust, and ice particles that form a ring

Where did the heavier elements that made up 2% of our solar nebula come from?

Heavier elements were formed in the cores of stars found in the early universe and through their explosions as supernovae. It took many billions of years of star formation and supernovae to produce a sufficient amount of heavy elements to begin to form solar systems that included rocky planets similar to Earth.

What is the only planet with rings?

Saturn is the sixth planet from the Sun and the second-largest planet in our solar system. Like fellow gas giant Jupiter, Saturn is a massive ball made mostly of hydrogen and helium. Saturn is not the only planet to have rings, but none are as spectacular or as complex as Saturn’s. Saturn also has dozens of moons.

What are the four major features of our solar system?

Four Major Characteristics of the Solar System

  • smaller size and mass.
  • higher density (rocks and metal)
  • solid surface.
  • few moons and rings.
  • closer to the Sun.

What are the two major types of planets?

Planets are generally divided into two groups: the terrestrial and the giant planets. The terrestrial planets are the four inner planets: Mercury, Venus, Earth, and Mars.
