Detailed explanation-1: -Gravity caused the cloud to contract and heat up. The cloud began spinning as it contracted, and it formed a disk shape.
Detailed explanation-2: -Shock waves from the explosion compressed the cloud of gas and dust. Compression made the cloud collapse, as gravity pulled the gas and dust together, forming a solar nebula. Just like a dancer that spins faster as she pulls in her arms, the cloud began to spin as it collapsed.
Detailed explanation-3: -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.
Detailed explanation-4: -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].
