This flattening is a natural consequence of collisions between particles in a spinning cloud. A cloud may start with any size or shape, and different clumps of gas within the cloud may be moving in random directions at random speeds. When the cloud collapses, these different clumps collide and merge, resulting in a flattened rotating disk.
Comments: Importantly, the cloud will be spinning slightly, because of random
motion effects.
As it collapses it will spin faster (conservation of angular momentum).
You can then explain what happens it in terms of the "centrifugal effect".
This effect is smallest near the axis of rotation of the cloud. So that the cloud will naturally flatten out.
A more technical explanation uses the "law of conservation of angular momentum".
This shows again the natural tendency to form a disk from a spinning cloud.

What happens to the rotation of a molecular cloud as it collapses to form a star?
The rotation rate increases and results in a disk of material around a protostar.
What is the Scale for universe molecular cloud galaxy star planet asteroid and atom biggest to smallest?
universe, molecular cloud, galaxy, star, planet, asteroid,atom
What is the birthplace of stars called?
Molecular cloud or Stellar Nursery .
Why does a planet travel in an orbit around the sun?
A solar system forms out of a large cloud of dust; as the cloud starts to rotate as it collapses in on itself, it tends to spin into a disc shape. The center starts coalescing and getting dense enough to turn into a star, and clumps all along the disc coalesce into planets. The reason why the cloud collapses in on itself, rotates, creates clumps that turn into the star and planets is all because of GRAVITY.
If you wanted to observe a molecular cloud in what wavelength of light would you most likely observe?
infrared.
What happens to the rotation of a molecular cloud as it collapses to form a star?
The rotation rate increases and results in a disk of material around a protostar.
As the cloud collapses the force of gravity drawing the cloud inward because?
As the cloud collapses the force of gravity drawing the cloud inward gradually becomes stronger because the strength of gravity follows an inverse square law with distance. hope that helps.
Why are stars born?
Stars form from collapsing clouds of dust and gas within regions of molecular clouds, often called stellar nurseries. As the cloud collapses its density and temperature increase until it eventually reaches the point where a start begins to form in the center of the cloud.
When a nebula collapses small regions in the cloud called?
globules
Whats pancaking in geography?
In geography, pancaking refers to the process in which tectonic plates collide, causing one plate to slide over the other, resembling the layers of a pancake. This process can lead to the formation of mountain ranges or other landforms, as the plates compress and deform.
The most common molecule in a molecular cloud is?
molecular hydrogen H2
What physical law explains why a cloud heats up as it collapses?
Law of Conservation of Energy.
As a rotating cloud collapses its rate of rotation?
The law of conversation of angular momentum.
Is Solar nebula a star?
No, its a molecular cloud.
What does the gravitational force in a molecular cloud depends on?
Density

What is the most abundant material in a giant molecular cloud?
Hydrogen
