The main islands are (from largest to smallest) Tenerife, Fuerteventura, Gran Canaria, Lanzarote, La Palma, La Gomera & El Hierro. The archipelago also includes a number of islands & islets: La Graciosa, Alegranza, Isla de Lobos, Montaña Clara, Roque del Oeste & Roque del Este. The islands are example of oceanic hot spot volcanoes above a slow-moving, thick oceanic plate. Lanzarote & Fuerteventura, the oldest islands, are in their erosional stage & recent volcanic activity is explained by a secondary mantle convection at the continental margin. Gran Canaria & Tenerife are in the post shield phase with rejuvenated volcanism. La Palma & El Hierro, the youngest of the island chain, are still above the hot spot & in their shield building phase.
