SOLAR SYSTEM

Detailed explanation-1: -HEATING: The temperature of the solar nebula increases as it collapses. As the cloud shrinks, its gravitational potential energy is converted to the kinetic energy of individual gas particles falling inward. These particles crash into one another, converting their kinetic energy into thermal energy.

Detailed explanation-2: -Gravitational collapse This giant cloud was made up of dust, hydrogen, and other gases. It began to collapse in on itself after becoming gravitationally unstable. This was possibly because of a nearby supernova-an exploding star-sending shock waves rippling through space.

Detailed explanation-3: -As it collapses, pressure from gravity causes the material at the center to heat up, creating a protostar. One day, this core becomes hot enough to ignite fusion and a star is born.

Detailed explanation-4: -Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula.

Detailed explanation-5: -Answer and Explanation: Turbulence is the phenomena that start the collapse of a nebula. A nebula is a diffuse mass of gas in outer space. A disturbance such as that caused by a supernova explosion can cause parts of the nebula to come close enough together that they begin to collapse under the force of gravity.
