Answer:
The gravity that initiated the collapse of the cloud of gas, rock, ice, and other materials that formed the solar system came from the accumulation of mass within the cloud itself. Over time, the force of gravity grew strong enough to overcome the outward pressure of the gas and dust in the cloud, causing it to collapse inward and eventually form the Sun and the planets.
Step-by-step explanation:
The gravity that initiated the collapse of the cloud of gas, rock, ice, and other materials that formed the solar system came from the accumulation of mass within the cloud itself. The cloud of gas and dust that formed the solar system was made up of tiny particles, some of which had a slightly greater mass than others. As these particles moved around and collided with one another, their gravitational forces began to accumulate and become stronger. The more particles that came together, the greater the force of gravity became.
Over time, the force of gravity grew strong enough to overcome the outward pressure of the gas and dust in the cloud, causing it to collapse inward. As the cloud continued to collapse, it became denser and denser, and the force of gravity continued to increase. Eventually, the pressure and temperature at the center of the cloud became high enough to initiate nuclear fusion reactions, leading to the formation of the Sun and the protoplanetary disk that eventually formed the planets.
In summary, the gravity that initiated the collapse of the cloud of gas, rock, ice, and other materials that formed the solar system came from the accumulation of mass within the cloud itself, and as the cloud continued to collapse, the force of gravity continued to increase.
