Why do many organisms native to india more like the organisms that are native to africa, than the organisms that are native to asia?

The Himalayas, stretching from east to west, form a barrier that largely prevents the movement of fauna southward or northward. Thus, Asia north of the Himalayas, with parts of western Asia and most of East Asia, belongs to the Palearctic (Old World) subregion of the Holarctic zoogeographic region (roughly, the Northern Hemisphere north of the tropics). Asia south of the Himalayas is called the Oriental, or Indian, region. The boundary dividing those zones east and west of the Himalayas is not well marked, however, as the mountain chains there often have a north-south trend facilitating migration of animals between them.

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.
