What is the planetary nebula theory?
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].
Which of the following describes a nebula?
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 are the two kinds of nebula theory?
The first is that the planets all rotate in the same direction. The second is that they all orbit within 6 degrees of a common plane. The third is that all the terrestrial planets, which are those within the orbit of the Asteroid Belt, are rocky, while those outside it are gaseous.
What are the three steps to the nebula theory?
Terms in this set (5)
- step one(4) -The solar nebula consisted of. -hydrogen,
- step two(2) -A disturbance.
- step three(2) -The solar nebula assumed a flat, disk shape.
- step four(2) -Inner planets began to form from metallic.
- step five(2) -Larger outer planets began forming from fragments.
What does a planetary nebula have in common with a supernova?
A planetary nebula is born when a low mass star dies (low mass means less than about 8 times the mass of the Sun), while the supernova is the death of a massive star. The ring of material was once part of the star in the center, but now has been ejected. The central star is now a white dwarf.
Which of the following best describes a nebula Quizizz?
Which of the following best describes a nebula? A disturbance in a nebula causes its center to begin collapsing from gravity. Dust becomes denser in a nebula, forming a star’s core. A nebula floats within the field of another star and brings in additional hydrogen.
Why does the solar nebula theory predict that planetary systems are common?
Why does the solar nebula theory predict that planetary systems are common? The solar nebula theory predicts that planets form as a natural byproduct of star formation. As the cloud collapses to form a star, small planetesimals form. These small planetesimals accrete matter to form planets.
When a planetary nebula gravitationally contracted to form our solar system what caused the central region to rotate faster and flatten into a plane?
When a planetary nebula gravitationally contracted to form our solar system what caused the central region to rotate faster and flatten into a plane? The conservation of angular momentum. Jupiter rotates once every 10 hours, more than twice as fast as the Earth.
What force causes the particles in a nebula to condense overtime?
gravity
According to the nebula hypothesis, the Solar System began as a nebula, an area in the Milky Way Galaxy that was a swirling concentration of cold gas and dust. Due to some perturbation, possibly from a nearby supernova, this cloud of gas and dust began to condense, or pull together under the force of its own gravity.
What do supernova remnant and planetary nebulae?
A planetary nebula is the death marker for a low mass star. A supernova is the massive explosion that marks the destruction of a more massive star.
Temperatures continued to increase
What is the evidence for the nebular theory?
¥The nebular theory holds that our Solar System formed out of a nebula which collapsed under its own gravity. ¥ observational evidence ÐWe observe stars in the process of forming today. Ð The are always found within interstellar clouds of gas. newly born stars in the Orion Nebula Solar Nebula The cloud of gas from which our own Solar System
What exactly does the Nebula do?
At its simplest,a Nebula is a giant cloud of gas and dust that is out there in space.
