The planets in the solar system were formed through a process known as accretion. Here's a step-by-step explanation:
1. The remaining materials from the sun's formation clumped together due to gravity. As the sun formed from a giant molecular cloud, it left behind a rotating disk of gas and dust called the protoplanetary disk. Over time, these materials began to clump together under the force of their own gravity.
2. The solid materials were forced out of the sun's disc and cooled down. Within the protoplanetary disk, dust particles collided and stuck together, gradually forming larger and larger bodies called planetesimals. As these planetesimals grew, some were able to accrete more material and become protoplanets.
3. The protoplanets continued to grow by colliding and merging with other protoplanets and planetesimals. Over millions of years, this process led to the formation of larger planetary embryos and eventually the planets we have today.
4. The gas particles released by the sun were pulled away and became solid. As the sun formed, it released a disk of gas that surrounded the protoplanetary disk. However, as the planets accreted more material, their gravity became strong enough to capture some of this gas and incorporate it into their atmospheres.
Overall, the formation of planets in the solar system involved the clumping of materials from the protoplanetary disk, their gradual growth through collisions and accretion, and the capture of gas particles from the surrounding environment.
The correct response is:
The remaining materials from the sun's formation clumped together due to gravity.
Explanation:
The formation of the planets in the solar system is believed to have occurred around 4.6 billion years ago. The process began with the formation of the sun, which occurred when a large cloud of gas and dust, called a nebula, collapsed under its own gravity.
As the sun formed, it underwent a process called accretion, where particles of gas and dust came together to form larger objects. The remaining materials that did not become part of the sun's core or the protoplanetary disk clumped together due to gravity.
The protoplanetary disk was a rotating disk of gas and dust that surrounded the young sun. Within this disk, the dust particles began to collide and stick together, forming larger and larger objects called planetesimals. These planetesimals eventually grew into protoplanets, which then further accumulated material to become the planets we know today.
So, the formation of the planets in the solar system was a result of the remaining materials from the sun's formation clumping together due to gravity in the protoplanetary disk.
