What does the nebular theory say?
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 nebular theory based on?
The nebular theory states that our solar system formed from the gravitational collapse of a giant interstellar gas cloud—the solar nebula. – (Nebula is the Latin word for cloud.) Kant and Laplace proposed the nebular hypothesis over two centuries ago. A large amount of evidence now supports this idea.
What is the nebular theory quizlet?
Nebular Theory. Nebular Theory: states that the Sun, when forming in the nebula, generated planets, asteroids, etc from spinning disk of matter called the accretion disk. – Most planets are on the same plane, "ecliptic" – all planets orbit in the same direction around the Sun.
What supports the solar nebula theory?
We see stars forming in the depths of giant clouds of gas and dust, and we even see young stars with disks of debris around them, which look just like the debris disk we think the planets formed from. Other lines of evidence come from simulations of the process.
What does nebular mean?
/ˈneb.jə.lər/ us. /ˈneb.jə.lɚ/ related to a nebula (= a cloud of gas or dust in space, appearing either bright or dark): a vast nebular cloud which covers most of Orion. the nebular stage of the universe.
What is the solar nebula quizlet?
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.
Which of the following can be explained using the nebular hypothesis?
The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems). It suggests the Solar System is formed from gas and dust orbiting the Sun.
How does the nebular theory form the solar system?
Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula. With the rise of the sun, the remaining material began to clump together.
What’s value of nebula?
Estimated Value Nebula is a godly knife that was originally obtainable by purchasing the Nebula Gamepass for 1,699 Robux.
How is nebula formed?
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.
When did the nebular theory happen?
about 4.57 billion years ago According to this theory, the Sun and all the planets of our Solar System began as a giant cloud of molecular gas and dust. Then, about 4.57 billion years ago, something happened that caused the cloud to collapse.
What is a nebula made from quizlet?
Is a interstellar cloud of 90% hydrogen, 10% helium , and trace amounts of heavier elements. Nebula are the basic building blocks of our universe, and contain the elements from which stars and solar systems are made.
Which hypothesis was out ruled by the solar nebular theory?
The nebular theory is a modification of the nebular hypothesis which said that the solar system formed from the gravitational collapse of an interstellar cloud of gas. It was formed when scientists used more sophisticated models of the processes that occur in a collapsing cloud of gas.
Which of the following describes 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 is nebula made of?
The roots of the word come from Latin nebula, which means a “mist, vapor, fog, smoke, exhalation.” Nebulae are made up of dust, basic elements such as hydrogen and other ionized gases. They either form through clouds of cold interstellar gas and dust or through the aftermath of a supernova.
How do stars form in a nebula?
Star Forming Nebula These knots contain sufficient mass that the gas and dust can begin to collapse from gravitational attraction. As it collapses, pressure from gravity causes the material at the center to heat up, creating a protostar. One day, this core becomes hot enough to ignite fusion and a star is born.
What does a nebula contain?
A nebula is an enormous cloud of dust and gas occupying the space between stars and acting as a nursery for new stars. The roots of the word come from Latin nebula, which means a “mist, vapor, fog, smoke, exhalation.” Nebulae are made up of dust, basic elements such as hydrogen and other ionized gases.
How do nebula form stars?
Star Forming Nebula These knots contain sufficient mass that the gas and dust can begin to collapse from gravitational attraction. As it collapses, pressure from gravity causes the material at the center to heat up, creating a protostar. One day, this core becomes hot enough to ignite fusion and a star is born.
What does it mean to characterize a nebula as diffuse quizlet?
Diffuse nebula. A cluster of stars within an intricate cloud of gas and dust. Evolution. The process a star goes through in its evolution. composition of a nebula.
How are stars and nebulae related?
A nebula is an enormous cloud of dust and gas occupying the space between stars and acting as a nursery for new stars. The roots of the word come from Latin nebula, which means a “mist, vapor, fog, smoke, exhalation.” Nebulae are made up of dust, basic elements such as hydrogen and other ionized gases.

What is nebula explain?
A nebula is an enormous cloud of dust and gas occupying the space between stars and acting as a nursery for new stars. The roots of the word come from Latin nebula, which means a “mist, vapor, fog, smoke, exhalation.” Nebulae are made up of dust, basic elements such as hydrogen and other ionized gases.
What happens in a nebula?
Nebulae are made of dust and gases—mostly hydrogen and helium. The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger.
What does a nebula consist of?
A nebula is an enormous cloud of dust and gas occupying the space between stars and acting as a nursery for new stars. The roots of the word come from Latin nebula, which means a “mist, vapor, fog, smoke, exhalation.” Nebulae are made up of dust, basic elements such as hydrogen and other ionized gases.
Can nebulae contain galaxies?
They can contain two or three galaxies, or they may have thousands of galaxies. Our home galaxy, the Milky Way, is part of a cluster known as the Local Group. Our nearest galactic neighbor, the Andromeda Galaxy, also belongs to the Local Group, as do several others.
What diffuse nebula?
Definition of diffuse nebula : any of the numerous luminous or dark formations or irregularly distributed dust and gas seen within the Milky Way galaxy and in other spiral galaxies but not including the planetary nebulae.
How are nebulae and stars Related quizlet?
– A nebula is an accumulation of dust and gas (a cloud) that is sometimes visible in the night and eventually collapses on itself creating a star. – The other way this type of nebula is formed is when a white dwarf star accretes material from other nearby stars.
How are stars formed in nebula?
Star Forming Nebula These knots contain sufficient mass that the gas and dust can begin to collapse from gravitational attraction. As it collapses, pressure from gravity causes the material at the center to heat up, creating a protostar. One day, this core becomes hot enough to ignite fusion and a star is born.
Is the solar system in a nebula?
The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. The Sun formed in the center, and the planets formed in a thin disk orbiting around it.
What happens in the nebula?
The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger. Eventually, the clump of dust and gas gets so big that it collapses from its own gravity.
