Put the following statements about the formation of the solar system based on the nebular hypothesis in the correct order from 1.
‘’oldest event’’ (first to form according to the nebular hypothesis) to 10. ‘’youngest event’’
(last to form in the solar system, based on the sequence of events listed) (10 marks).

list of events :
• sun took 10 million years to form, nuclear fussion marked the birth of the sun.
• core of nebular cloud grows under influence of gravity and becomes denser and hotter
• clusters of molten metals and dust particles stuck together to form rocks
• material falls towards the core of the nebular cloud, which increases in speed, and flattens
into a giant spinning disk
• molten metals and dust particles stuck together to form clusters
• mutual gravity caused rocks to come together, eventually to form proto-planets
• increasing temperature in nebular cloud generates enough energy to trigger nuclear
fussion
• heavier rocky material, with metallics with higher melting points are left nearer to sun
• nebula composed of giant spinning cloud of mainly gases (hydrogen and helium) and dust.
• lighter gases were swept away from center of solar system into outer solar system
