Arrange the events in the order that they’re likely to occur leading up to the formation of a solar system. the temperature increases. the nebula shrinks. the nebula spins. a cloud of dust and gas forms. the nebula flattens into a disk. nuclear fusion takes place.

1. A cloud of dust and gas forms  

2. The nebula shrinks  

3. The temperature increases  

4. The nebula spins  

5. The nebula flattens into a disk  

6. Nuclear fusion takes place

Explanation:

The sun was born in solar nebula. The solar system was formed in the following events.

Firstly, a cloud of dust and gas formed which. This is the stellar nursery - the nebula. The nebula started shrinking under its own gravitation due to which the temperature also started rising. It started spinning and shrinking more under its own gravitational force. A disk like structure is formed. A Protostar Sun is born. The temperature and pressure increases sufficiently such that Nuclear fusion kicks in which generates heat and light. The remnant forms the planets, asteroids and other parts of the solar system.

The sun born from dust, this shrinks and then temperature and pressure increases and finally nuclear fusion  occur this release energy.

The origin of Solar system,

It is completed in following Events:

    1. A cloud of dust and gas forms  

     2. The nebula shrinks buy its own gravitational force.

     3. The temperature and pressure increases.

     4. The nebula start spinning  

     5. The nebula flattens into a disk., known as Protostar.  

     6. Nuclear fusion takes place. this emits a lot of energy.

Hence, we can conclude that sun born from dust, this shrinks and then temperature and pressure increases and finally nuclear fusion  occur this release energy.
