According to the nebular hypothesis our solar system formed from a huge rotating cloud formed by?
The nebular hypothesis posits that our solar system formed from a large rotating cloud of dust and gas composed mostly of hydrogen and helium, leftover from previous supernova explosions. Over time, gravity caused the cloud to collapse and form a protostar at its center, with a surrounding disk from which planets eventually coalesced.
What is a contracting cloud of gas and dust with enough mass to form a star?
it's a protostar
Nebular hypothesis of the formation of the earth?
Early attempts to explain the origin of this system include the nebular hypothesis of the German philosopher Immanuel Kant and the French astronomer and mathematician Pierre Simon de Laplace, according to which a cloud of gas broke into rings that condensed to form planets. Doubts about the stability of such rings led some scientists to consider various catastrophic hypotheses, such as a close encounter of the Sun with another star. Such encounters are extremely rare, and the hot, tidally disrupted gases would dissipate rather than condense to form planets.
According to the nebular hypothesis our solar system formed from a huge rotating cloud made mostly of what?
According to the nebular hypothesis, our solar system formed from a huge rotating cloud made mostly of hydrogen and helium gas, with trace amounts of heavier elements. The cloud, or nebula, slowly collapsed under its own gravity, leading to the formation of the sun and the planets.
Who created the nebular theory?
The nebular theory was proposed by the philosopher Immanuel Kant and later expanded upon by the mathematician Pierre-Simon Laplace in the 18th century. It suggests that the solar system formed from a rotating cloud of gas and dust.
When vapor cools in a cloud?
it begins to condenses.
What is the steps of nebular theory?
The nebular theory posits that the solar system formed from a rotating cloud of gas and dust, known as a solar nebula. The process begins with the gravitational collapse of this nebula, leading to the formation of a protostar at its center. As the protostar continues to accumulate material, it ignites nuclear fusion, forming a star, while the remaining material flattens into a rotating protoplanetary disk. Within this disk, particles collide and coalesce to form planets, moons, and other celestial bodies.
What is it called when the nebula begins collapsing and turning into a small spinning cloud?
This stage is called protostar formation. As the nebula collapses due to gravity, it begins to spin faster and forms a hot, dense core known as a protostar. This marks the beginning of the process that will eventually lead to the formation of a new star.
The nebular model explains?
The nebular model explains how our solar system formed from a rotating cloud of gas and dust called a solar nebula. Gravity caused the nebula to collapse, forming a central protostar surrounded by a spinning disk. Over time, the material in the disk clumped together to form planets and other solar system bodies.

Was the earth formed of a nebular cloud?
a nebular creates stars as it caves in by its own gravity!
What is a star called that begins as a large cloud of dust and gas?
A star that begins as a large cloud of dust and gas is called a protostar. It forms as gravity causes the dust and gas to clump together and initiate the process of nuclear fusion in its core.
What is the beginning stage in the formation of a star called?
The beginning stage in the formation of a star is called a protostar. This is when a dense core within a molecular cloud begins to accumulate gas and dust, causing it to heat up and eventually become a star.
What is a star called before it is born?
A star is called a protostar before it begins nuclear fusion in its core and officially becomes a star. During this stage, a protostar is formed from a collapsing cloud of gas and dust, as gravity pulls material together and heats up the core.
What comes first a Nebula or a protostar?
A nebula comes first; it is a large cloud of gas and dust in space. Under the influence of gravity, regions within the nebula can collapse to form a protostar. As the material falls inward, the protostar heats up and begins the process of nuclear fusion, eventually leading to the formation of a star.
What are the main steps of the nebular hypothesis?
The nebular hypothesis describes the formation of the solar system from a giant rotating cloud of gas and dust, known as a solar nebula. The main steps include the collapse of the nebula under its own gravity, leading to the formation of a protostar at its center. As the protostar forms, surrounding material flattens into a rotating disk, where particles collide and coalesce to form planetesimals. These planetesimals further collide and merge, eventually forming the planets, moons, and other bodies of the solar system.
What slow down the contracting of a star forming cloud when it makes a protostar?
trapping of thermal energy inside the protostar
