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. You just studied 12 terms!
What are 3 pieces of evidence that support the solar nebula theory?
Comets, asteroids, and meteorites recovered on Earth also provide a number of clues and evidence of Nebular-type development. And the motions of most solar system objects orbit and rotate in an organized fashion.
What elements were in the solar nebula?
The planets in our Solar System are believed to have formed from the same spinning disc of dust that formed the Sun. This disc, called the solar nebula, was composed mainly of hydrogen and helium, but also had other elements in smaller proportions.
What was the main component of the original solar nebula?
About 4.6 billion years ago our solar system formed from a cloud of gas and dust which slowly contracted under the mutual gravity of all of its particles. The cloud was made largely of hydrogen (H) with some helium (He) and small amounts of the remaining naturally occurring chemical elements.What three major changes occurred in the solar nebula?
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 of the following types of material can condense into what we call ice at low temperatures?
What are the three major stages of planet formation?
After becoming distinct planets, they went through four stages of formation: Differentiation, Cratering, Flooding and Surface Evolution. For Earth, these changes led to the planet we know today, layered with an iron core, a weathered, shifting surface, water and life.
What are the main constituents of the Jovian planets?
Rather than having thin atmospheres around relatively large rocky bodies, the jovian planets have relatively small, dense cores surrounded by massive layers of gas. Made almost entirely of hydrogen and helium, these planets do not have solid surfaces.
What is the solar nebula quizlet?
Answer: Solar nebula is a massive cloud of gas and dust that collapses into itself, compresses the gas, heats up, and eventually (assuming its massive enough) begins nuclear fusion creating a star. The dust clumps together to form planetary bodies and whatnot.What is nebula in solar system?
The solar nebula was the rotating, flattened disk of gas and dust from which the solar system originated ∼4.6 Ga (Figure 1). … Artist’s concept of the solar nebula, showing the early Sun surrounded by a flattened disk of gas, dust, and growing planetesimals.
How did particles in the solar nebula from Earth?the growth of a particle by addition of material from surrounding gas, atom by atom. In the solar nebula, dust grains were continuously bombarded by atoms of gas. Condensation can increase the mass of a small grain rapidly, which converted some of the gas into solid bits of matter.
Article first time published onWhat are the three 3 most abundant elements in the solar system?
The solar system consists of the sun, the eight planets and several other miscellaneous objects, such as comets, asteroids and dwarf planets. The most abundant elements among these objects are hydrogen and helium, primarily because the sun and the four largest planets are predominantly made up of these two elements.
What are the energy components of the solar system?
The four major components of a solar energy system are the panels, inverter(s), racking and solar battery storage unit(s) (if desired). Solar panels are the most visible element of your system, which is why you’re likely the most familiar with it.
What are the elements of the solar system?
Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids.
What is the approximate chemical composition of the solar nebula?
-This cloud of gas and dust that gave birth to our solar system is called the solar nebula. According to modern science, what was the approximate chemical composition of the solar nebula? C. Roughly equal proportions of hydrogen, helium, water, and methane.
What are the 4 stages of solar system formation?
After becoming distinct planets, they went through four stages of formation: Differentiation, Cratering, Flooding and Surface Evolution.
Which of the following were most abundant in the solar nebula as the planets were formed?
Hydrogen and helium gas were the most abundant by far, comprising about 98% of the solar nebula.
What are the main constituents of the Jovian planets quizlet?
Which of the following is not a general characteristic of the four jovian planets in our solar system? They are composed mainly of hydrogen, helium, and hydrogen compounds.
What are three characteristics of all Jovian planets?
The Jovian planets are Jupiter, Saturn, Uranus, and Neptune. They orbit far from the sun. These planets have no solid surfaces and are essentially large balls of gas composed primarily of hydrogen and helium. They are much larger than the terrestrial planets (Earth, Mercury, Venus, and Mars).
What are the three planets that have rings?
Since then, astronomers – who study the universe and everything in it, like planets – have used bigger and better telescopes to find rings around all of the outer gas giant planets: Jupiter, Saturn, Neptune and Uranus.
What is the first stage of a solar system?
The first stage of planetary development is called differentiation, the settling of dense material, like iron-rich minerals, into the center of a planet and the rising of less dense material, such as silicon-rich minerals, to the surface.
What are the four stages of earth crust?
- 3.1 Primordial crust.
- 3.2 Secondary crust.
- 3.3 Tertiary crust.
How did the solar system form?
The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. … After the Sun ignited, a strong solar wind cleared the system of gas and dust. The asteroids represent the rocky debris that remained.
What are the types of nebulae?
There are five types of cloudy or nebulous objects in the sky: planetary nebulae, emission nebulae, reflection nebulae, dark nebulae and supernova remnants.
What creates a nebula?
The Short Answer: A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form.
What are the four major features of our solar system?
- smaller size and mass.
- higher density (rocks and metal)
- solid surface.
- few moons and rings.
- closer to the Sun.
What are the four key features of our solar system?
Four major features provide clues: (1) The Sun, planets, and large moons generally rotate and orbit in a very organized way. (2) With the exception of Pluto, the planets divide clearly into two groups: terrestrial and jovian. (3) The solar system contains huge numbers of asteroids and comets.
What happened to the solar nebula quizlet?
By the time planetesimals grew to a large enough mass to hold onto an atmosphere, the solar nebula had been blown away. There was no material to create planetesimals beyond the orbit of Neptune. By the time planetesimals grew to a large enough mass to hold onto an atmosphere, the solar nebula had been blown away.
What are the characteristics of a solar nebula?
Solar Nebula. Our solar system began forming within a concentration of interstellar dust and hydrogen gas called a molecular cloud. The cloud contracted under its own gravity and our proto-Sun formed in the hot dense center. The remainder of the cloud formed a swirling disk called of the solar nebula.
What two forces caused the solar nebula to develop into the sun?
Energy from collisions and pressure from gravity caused the center of the solar nebula to become hotter and denser.
What are the three 3 most abundant elements in the earth's crust as illustrated in the graph?
The mass-abundance of the nine most abundant elements in the Earth’s crust is approximately: oxygen 46%, silicon 28%, aluminium 8.3%, iron 5.6%, calcium 4.2%, sodium 2.5%, magnesium 2.4%, potassium 2.0%, and titanium 0.61%. Other elements occur at less than 0.15%.
What are the three most common gases in each planet's atmosphere?
Nitrogen, oxygen and argon are the three most abundant elements in the atmosphere, but there are other key components that are required for supporting life as we know it on earth. One of those is carbon dioxide gas.
