Explain how scientists use geologic time to determine the age of landforms.

Explanation:Following are the techniques or methods or approaches we can say that were used by the scientists to determine the geologic age:

1. Relative age dating

2. Absolute age dating.

3. Radiation measurement.

4. Stratigraphic superposition.

5. The fossil record.

The scientists used the method of relative dating to divide Earth's past in different chunks of time when alike organisms were on Earth. After that, to discover the actual number of years ago that events occurred, the scientists used the method of absolute dating.

events in order:

1.       vishnu schist

2. zoroaster granite

3. bass limestone

4. hakatar   shale

5. igneous intrusion

6. shinumo quartzite

7. dox sandstone

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.
