43-49 Arrange the following in the correct chronological order by placing the numbers 1-7 in front of
the statements. Number 1 is the first event to occur.
____6___Temperature and pressure become great enough in core to cause hydrogen to fuse to heliumprotostar
___4____During collapse, the interstellar gas forms a disk due to the rotation of the cloud.
___5___Gravity draws gas and dust into a central core, heating it.
___1____Slowing spinning interstellar cloud of gas composed mostly of hydrogen and helium.
___7____As the process of fusion (H->He) continues, outward pressure balances inward gravity…a star
is born.
___3____Particles in the densest part of the cloud cause it to begin gravitational collapse.
___2____An event causes anomalies to appear in the interstellar gas.
