Galapagos is located on the Nazca tectonic plate. The islands were formed through the layering and lifting of repeated volcanic action.Each major island, with the exception of the largest island, Isabela, consists of a single large volcano. Isabela was formed when six volcanoes joined above sea level.

Were the Galapagos Islands formed?
The Galápagos Islands were formed as a result of several of Earth’s internal processes. The Galápagos’ stationary hot spot formed a chain of volcanoes as the Nazca crustal plate moved east-southeast above the hot spot like a conveyor belt.
How was the Galapagos Rift formed?
Submarine eruptions at mid-ocean ridges produce pillow lavas, which form as lava slowly erupts from a fissure on the sea floor. The E-W-trending Galápagos Rift located north of the Galápagos Islands is an oceanic spreading ridge between the Cocos plate to the north and the Nazca plate to the south.
What type of plate boundary formed the Galapagos Islands?
Nazca tectonic plate
The Galapagos Islands are located on the Nazca tectonic plate. This is a perpetually moving piece of the earth’s crust that is heading eastward over what is known as the Galapagos Hotspot. It’s found near the equator, not far from the divergent plate boundary with the Cocos Plate.
What is the history of the Galapagos Islands?

Why are the Galápagos Islands important?
Facts. Six hundred miles off the coast of Ecuador lie the volcanic islands of the Galápagos, famous for a wealth of unique plants and animals found nowhere else in the world. The Galápagos Islands were the source of Darwin’s theory of evolution and remain a priceless living laboratory for scientists today.
What makes the Galapagos Rift unique?
The Galapagos Islands are uniquely located on both sides of the equator in both the Northern and Southern Hemispheres. The islands are situated at a point in the Pacific Ocean where three ocean currents collide, creating a unique area in the sea where warm and varying degrees of cold water meet.
What happened to Galapagos Island?

Which natural process created the Galápagos Islands when was the last eruption among these islands?
As the Nazca Plate passed over the Galápagos hotspot — a point where magma pushes through the crust — volcanoes erupted, and eventually, the Galápagos Islands were formed.

Why are the finches now living in the Galapagos Islands different from the original species to land there Select all that apply?
Why are the large finches now living on the Galápagos Islands different from the original source population from a nearby island?Genetic drift occurred in the two populations. Natural selection favored individuals that were more fit in the new environment.
Why are the Galapagos Islands so diverse?
The Galapagos Islands are so biodiverse because of the many different habitat zones that can be found across the Islands. There are coral reefs, highland forests, sand dunes and scrubland, and the changing habitats from island to island. Species diversity is only one piece of the biodiversity puzzle.
