1. Describe what figure 8.29 tells us about of North America.

2. What is Rodinia? Explain the climate issue happening at the time.

3. What is a sequence? Explain the significance of the Sauk and Tippecanoe sequences.

4. Describe the major event going on tectonically in eastern North American margin in the late Paleozoic.

Expert Solution

1)The figure is not given.

2)Rhodonia is a supercontinent that existed during Mesoproterozoic (1600million -750million age).

Climate issues-

1)During this second snowball earth phenomenon occurred (750millionyears ago),wide spread glaciation was there in earth surface

2)Ozone layrr started to form around 1400 million years ago,before that ultraviolet Ray's causing damage to evolving of organisms

3)Edicaria fauna stated to evolved at the last stage of rhodonia approximately 700million.

4)wide spread regression of sea level occurred caused evaporation of sea water from shallow area. Evaporite started to deposit near sea coast.

5)Due to breaking of supercontinent acidic and alkaline magmatism occurred. Acidic volcano Malani volcanic happened in Indian subcontinent. Increased volcanic activity indirectly provides inorganic nutrient content to ocean for development of ocean organisms.

3)Sequences is a statigraphic unit which is bounded by unconformity indicates deposition of sediments in a particular sequences.

Sauk and Tippecanoe sequences are marine transgressions deposition occured during from precambrian to palaezoic

Sauk sequences deposited in late precambrian to mid ordovician approximately 650 million to 460 million ages

Similarly Tippecanoe sequences deposited during middle devonian to early devonian approximately 460 million to 400 million years ago.

This sequences widely gained importance because of shallow water deposition sandstone and clastic carbonate deposition.

4)During late carboniferous and Permian North America collided with Africa.

At the boundary Permian-Triassic age formation of pangea occurred that is approximately 250 million ago.

Widespread carbonate deposition occurred in mssissipian age.

After pangea break up eastern margin became passive continental margin.
