The region has been experiencing the ozone hole every year since the 1980s.

Antarctica

Explanation: Ozone hole was discovered during 1980 in Antarctica. The reason being weather in the ozone layer.

The weather in the Antarctic region is cold that favors the formation of clouds. These clouds helps in the ozone layer formation. Maximum hole depletion is observed here only.

Other regions of the earth does not favors the formation of clouds that favors ozone formation.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.

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.
