Explanation:
scientists believe that the solar system was formed when some star had its explosion and due to its explosion there were waves generated in the space thus squeezing clouds and dust eventually gravity pulling everything together forming solar nebula. the clouds spin faster and faster thus making it into a thin disk and also the cloud becoming hotter and dense thus forming stars.
The correct answer is "greenhouse gases." Certain gases in the atmosphere, like carbon dioxide, nitrous oxide, and methane, absorb heat and prevent it from escaping into space. These gases are called greenhouse gases.
