|---|---|
 cloud nebula | clumping occurs from gas and dust. gravity increases and this leads to friction. |
| protostar | heat is produced and more clumping occurs and pressure increases. |
| main sequence star | first light is produced. nuclear fusion takes place and helium pressure is added. |
| red giant | cooler surface temperature, due to its large surface area. the outside explodes while the inside implodes but the helium burning caused the surface to them expand. |
