As rain mixes with chemicals such as sulfur dioxide in the air, acid rain is produced. this may result in
(a) lowering the ph in ponds, thus limiting the survival of many organisms
(b) lowering the ph in ponds, thus affecting water temperature
(c) raising the ph in ponds, thus encouraging the growth of organisms
(d) raising the ph in ponds, thus limiting animal development
(e) depleting atmospheric carbon dioxide available for photosynthesis

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.
