The Galapagos islands are considered to be "young" islands. Explain what this means.

The Galapagos are considered 'young'because they were created relatively recently in geologic history. The islands are located on the Nazca oceanic plate and were formed by hot spot volcanic activity. As the tectonic plate moves over the hot spot repeated eruptions form islands. The Galapogus islands are thought to be no more than 5 million years old.
