Which of the following helps support molecular clouds against gravitational collapse?

Question

Quizplus · Accepted Answer

Molecular clouds are large and dense regions of interstellar gas and dust where stars form. These clouds are subject to the force of gravity that tries to collapse them into smaller and denser regions, which would eventually lead to the formation of stars. However, there are three main factors that can help support molecular clouds against gravitational collapse: thermal pressure, turbulence, and magnetic fields. Thermal pressure arises from the temperature of the gas in the cloud, which can help counterbalance the gravitational force. Turbulence refers to the chaotic motion of the gas, which can create eddies and turbulence that help support the cloud against collapse. Finally, molecular clouds are threaded with magnetic fields that can provide additional support against collapse. All three factors work together to create a balance between gravity and other forces that can help maintain the size and shape of molecular clouds.
