Explain why the material surrounding a young star forms a disk?
The prograde rotation of the collapsing cloud of gas and dust results in conservation of angular momentum, causing the material to flatten into a disk shape. This disk of material, known as a protoplanetary disk, is where planets are thought to form through the process of accretion and gravitational interactions.
How does an accretion disk form?
An accretion disk forms around a massive object, such as a black hole or a young star, when material falls into its gravitational pull. The material spirals inward due to angular momentum conservation, forming a disk-shaped structure as it moves closer to the central object. Friction within the disk causes the material to heat up and emit energy in the form of radiation.
What is the compact gas and dust that became a planet?
A protoplanetary disk is a concentration of gas and dust around a young star that eventually comes together to form planets. As the material in the disk begins to clump together due to gravity, it forms planetesimals which then grow into planets through accretion and collisions.
What is a disk containing cell wall material called?
A disk containing cell wall material is called a cell plate. It forms during the plant cell division process to help separate the two daughter cells.
How are planets made wikipedia?
Planets are formed from a disk of gas and dust surrounding a young star known as a protoplanetary disk. Over time, the particles within the disk collide and stick together, gradually forming larger and larger objects. Eventually, these objects grow into planetesimals, which further accrete material to become planets.
What are the major steps of solar system formation in the correct order?
Collapse of a giant molecular cloud: Gravity causes a cloud of gas and dust to collapse under its own weight. Formation of a protostar: The collapsing cloud forms a protostar at its center due to increased pressure and temperature. Accretion disk formation: Surrounding material forms a disk around the protostar from which planets and other celestial bodies will eventually form. Planet formation: Dust particles in the disk collide and stick together, gradually forming planetesimals that will eventually accrete into planets.
What is the membranous disk containing cell wall material in plants?
The membranous disk containing cell wall material in plants is called the "cell plate." It forms during cell division in plant cells and eventually develops into a new cell wall that separates the daughter cells.
What is protoplanet nebular model?
The protoplanetary nebular model is a theory that describes how planetary systems form from a disk of gas and dust surrounding a young star. According to this model, the planets form as material within the disk accretes onto planetesimals, which eventually grow into planets through collisions and gravitational interactions. This model is widely accepted in planetary science for explaining the formation of our own solar system and others.
