Adaptive radiation is one pattern of a. speciation b. isolation c. mass extinction d. stabilizing selection

A. Speciation

Explanation:

The adaptive radiation can simply be defined as rapid diversification, or speciation, of one ancestral species, to numerous different species. This happens mostly as a result of ecological opportunities. Practically. when there are numerous niches free in an ecological system, one species will start to diverge into numerous other species if it has the opportunity. Groups of the species will start to adapt to certain niche that is free, thus developing their own unique traits, gradually becoming distinct enough that they create another species.

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.
