How would the universe be different if massive stars did not explode at the wnd of their lives

The extreme energy released in supernovae actually destroys the nuclei of atoms, causing heavier elements to reform and dispersing them throughout the universe. Before supernovae, the only three elements in the universe were hydrogen, helium, and lithium. More stable elements like carbon and oxygen that are necessary for life were created by them, and without them, we could not exist.

8. tapeats limestone

9. bright angel shale

10. muav limestone

11. temple butte limestone

12. redwall limestone  

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.
