Rotates in the opposite direction to other planets in the solar system a) Mercury b) Venus c) Earth d) Mars 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.
