Geologic evidence for the repeated occurrence of continental collision and rifting since the Archean has led to the hypothesis that the continents periodically coalesced into large landmasses called supercontinents. The best known of the supercontinents include Gond-wana (Fig. 3.4) and Pangea (Fig. 11.27), which formed in the latest Proterozoic and late Paleozoic times, respectively. Other supercontinents, such as Rodinia and Laurussia, also have been proposed for Late Proterozoic and late Paleozoic times, respectively. Processes in the mantle that may have led to their assembly and dispersal are discussed in Section 12.11.

Lets start by identifying what exactly certain boats are. Sometimes the terminology can get lost on beginners, so well look at some of the most common boats and what theyre called. These boats are exactly what the name implies. They are meant to be used for fishing. Most fishing boats are powered by outboard motors, and many also have a trolling motor mounted on the bow. Bass boats can be made of aluminium or fibreglass.
