Detailed explanation-1: -How were temperatures distributed across the protoplanetary disk that formed our solar system? Temperatures were greater at the core, and cooler at the outer regions.
Detailed explanation-2: -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. Small particles drew together, bound by the force of gravity, into larger particles, according to the core accretion model.
Detailed explanation-3: -What does a protoplanetary disk most likely have in common with Earth’s Solar System? They both are in motion and are held together by gravity.
Detailed explanation-4: -1.17.2.3 Disk Temperatures and Particle Drift Protoplanetary disks are heated by radiation from the central star and the release of gravitational energy as gas falls inwards through the disk.
