The diagram below shows how South America and Africa were once joined in the past. Name the phenomenon that lead to the world to have separated continents.

here are the answers to your questions: 3.3.1 The phenomenon that led to the world having separated continents is continental drift (or plate tectonics). 3.3.2 The Ostrich is found in Africa. 3.3.3 A unique characteristic common to both Rhea and Ostrich is that they are large, flightless birds. 3.3.4 The study of the distribution of existing and extinct organisms in different geographical areas is called biogeography. 3.3.5 South America and Africa belonged to the major supercontinents of Gondwana and Pangaea. 3.3.6 Birds like the Rhea and Ostrich, despite being different species, share similar characteristics because they evolved from a common ancestor that lived on the supercontinent Gondwana. When Gondwana began to break apart due to continental drift, the landmasses carrying these ancestral birds separated. The populations became geographically isolated on different continents (South America for the Rhea, Africa for the Ostrich). Over millions of years, these isolated populations evolved independently, adapting to their specific environments, leading to the formation of distinct species while retaining many shared traits from their common ancestor.
