How were gothic cathedrals different from romanesque churches

The architecture style is different. romanesque churches came first. they were bulky, strong and had really thick walls. their windows were regular roman arched shapes. they usually have lower ceilings and not much light inside.
Gothic cathedrals came later. they have pointed arches, lots of tall windows for light stained glass and flying buttresses to help support the higher and thinner walls.
