The tectonic setting of the hotspot is complicated by the Galapagos Triple Junction of the Nazca and Cocos plates with the Pacific Plate.

What surrounds the Galapagos Islands?
The islands are surrounded by the Galapagos Marine Reserve which was created in 1986 (70,000 km2) and extended to its current area (133,000 km2) in 1998, making it one of the largest marine reserves in the world.
What plates are involved in the Galapagos rise?
The Galapagos Rise is a divergent boundary located between the South American coast and the triple junction of the Nazca Plate, the Cocos Plate, and the Pacific Plate. The volcanically active Galapagos Islands exist on the Galápagos hotspot above the Galapagos Rise.
Is the Galapagos Fracture Zone a divergent plate boundary?
These structures are seen in the GTJ area, implying that not only divergent boundaries are present but smaller convergent/transform as well. Determining relative ages of the geology in the area is challenging due to consistent volcanic activity along spreading ridges and trenches bordering each plate boundary.
How far apart are the Galapagos Islands from each other?
The Galapagos Islands are about 1,000 km (600 miles) off the west coast of South America.
What country is closest to the Galapagos Islands?
The islands are located in the eastern Pacific Ocean, 973 km (605 mi) off the west coast of South America. The closest land mass is that of mainland Ecuador, the country to which they belong, 926 km (500 nmi) to the east.
Where is the Galapagos Ridge?
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 is the example of convergent plate boundary?
The Pacific Ring of Fire is an example of a convergent plate boundary. At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents.
Where is the Nazca plate moving?
The Nazca Plate is moving eastwards, towards the South American Plate, at about 79mm per year.
Is Galapagos a oceanic island?
The Galapagos are a group of volcanic islands located on the equator roughly 1000 km (600 miles) west of the South American coast. Like many oceanic islands, such as Hawaii, the Azores, and Reunion, the Galapagos are thought to be the product of a mantle plume.
Are the Galápagos Islands a convergent boundary?
The Galapagos contains three types of plate boundaries. Divergent and transform plate boundaries are located within the archipelago, while a convergent boundary exists directly off the coast of Ecuador.
Where are fracture zones located?
Fracture zones are common features in the geology of oceanic basins. Globally most fault zones are located on divergent plate boundaries on oceanic crust. This means that they are located around mid-ocean ridges and trend perpendicular to them.
Can I visit the Galapagos Islands?
Ninety-five percent of the land area of Galapagos is designated as protected by the Galapagos National Park Directorate (GNPD), and tourists are permitted to explore specific visitor sites only with Park-certified naturalist guides (refer to the Park rules).
How long is the boat ride from Ecuador to Galapagos?
3 days
By sea it takes 3 days to reach the Galapagos Islands from Ecuador. Boats depart from Guayaquil to the Galapagos. Most often these are cargo ships with basic accommodations not matching the luxury cruises in the archipelago.
What are Galapagos Islands famous for?
The islands are known for their famously fearless wildlife and as a source of inspiration for Darwin’s theory of evolution. And that’s just part of the story. Born of fire: The Galápagos Archipelago is one the most volcanically active areas in the world.
Who controls Galapagos Islands?
Ecuador
2. Who Owns the Galapagos Islands? Similar to the way that the Hawaiian Islands are a part of the United States, the Galapagos Islands are a part of the neighboring country of Ecuador, located in South America.
How far is Galapagos Islands from the equator?
2,811.78 mi
How far is Galapagos from the equator and on what hemisphere is it? Galapagos is 2,811.78 mi (4,525.12 km) north of the equator, so it is located in the northern hemisphere.
What are 3 characteristics of the Galapagos tortoise?
Shell functions (Chiari et al. 2009)
- Protection.
- Regulation of body temperature (thermoregulation)
- Facilitation of mating and reproduction.
- Ability to turn over (“self-righting”)
- Locomotion.
- Storage of water, fat, and wastes.
What is Map of plate boundaries?
A map of the tectonic plates of the earth showing the different boundary types in different colors. Locations where plates collide (convergent boundaries) are shown in red. Locations where plates are spreading (divergent boundaries) are shown in yellow.
What plate residents live in Tallahassee?
What plate do residents of Tallahassee Florida live on? North American Plate.
Is the Nazca plate convergent or divergent?
The Nazca plate is an oceanic tectonic plate in the southeastern Pacific Ocean that shares both convergent and divergent boundaries, corners multiple triple junctions, contains three seamount chains, overrides four hotspots, and is responsible for the creation of the Andean orogeny (Figure 1).
