The Galapagos hotspot (estimated to be around 150km wide) is located to the west of the Galapagos Archipelago. The Islands are located in the northern part of the Nazca plate, which is slowly drifting in a southeasterly direction at a rate of approximately 5cm per year.

Is Galapagos Islands biodiversity hotspot?
Reached by four major ocean currents, including upwellings of deep water rich in nutrients, the Galápagos Islands off the coast of South America are a hotspot of biodiversity.
Where are the hotspots located?
Most of these are located under plate interiors (for example, the African Plate), but some occur near diverging plate boundaries. Some are concentrated near the mid-oceanic ridge system, such as beneath Iceland, the Azores, and the Galapagos Islands. A few hotspots are thought to exist below the North American Plate.
What is an example of a hotspot island chain?
The Hawaiian Islands and the chain of seamounts that continue their trend for about 6,000 kilometers (3,750 miles) into the northwest Pacific Ocean are an example of a hotspot track. The Island of Hawaii is the youngest, and most active, volcano in the chain.
What is an example of a continental hotspot?
Columbia Plateau —Yellowstone Hotspot Track. Volcanic rocks in the Pacific Northwest show the effects of a tectonic plate riding over a deep-mantle hotspot.A hotspot is like the hot wax rising in a lava lamp.
Why might the Galapagos Islands be considered a biodiversity hotspot?
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.
What is the biodiversity of Galapagos?
The Galapagos Islands are home to some of the highest levels of endemism (species found nowhere else on earth) anywhere on the planet. About 80% of the land birds you will see, 97% of the reptiles and land mammals, and more than 30% of the plants are endemic.
What are 3 examples of hotspots?
Examples include the Hawaii, Iceland and Yellowstone hotspots. A hotspot’s position on the Earth’s surface is independent of tectonic plate boundaries, and so hotspots may create a chain of volcanoes as the plates move above them. There are two hypotheses that attempt to explain their origins.
Is Japan a hotspot?
Japan is one of the 34 global biodiversity hotspots, as identified by Conservation International.This approach means those parts of a large-scale hotspot particularly rich plant diversity and of global importance for conservation (bioquality) can be identified.
What is the hotspot?
Mobile WiFi hotspots
Did you know that you can use your iPhone or many Android smartphones as a WiFi hotspot? By turning on this feature, your phone uses its cellular data to create a WiFi hotspot. You can then connect a computer or other device to this hotspot to access the internet.
What hotspot is located on the African plate?
13. Name the hotspot located on the African Plate. Canary Islands Hot Spot 14.
Is Yellowstone a hotspot?
Yellowstone sits above a melting anomaly within the Earth, called a “hotspot.” This hotspot is powered by a plume of hot (but not molten) material that may extend as deep as the boundary between the planet’s mantle and core.
Why is Hawaii a hotspot?
This upwelling of molten rock, known as a “hot spot,” creates volcanoes that spew out lava (magma that reaches Earth’s surface). The lava then cools and hardens to create new land. The Hawaiian Islands were literally created from lots of volcanoes—they’re a trail of volcanic eruptions.
Is Mt St Helens a hotspot?
Helens in Washington state. NASA scientists took these visible and infrared (IR) digital images of the mountain on Tuesday, Oct. 12, that show an increase in the number of hot spots as well as a plume of smoke coming from the crater. Bright red in the crater indicates hot spots, and blue indicates snow and the plume.
What type of boundary are hotspots?
Hot spot volcanoes occur far from plate boundaries. Because the hot spot is caused by mantle plumes that exist below the tectonic plates, as the plates move, the hot spot does not, and may create a chain of volcanoes on the Earth’s surface.
Are the Canary Islands a hotspot?
The Canary hotspot, also called the Canarian hotspot, is a hotspot and volcanically active region centred on the Canary Islands located off the north-western coast of Africa.Volcanism is believed to have first started about 70 million years ago.
Why are the Galapagos Islands 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.
How did the Galapagos Islands become so diverse?
Repeated volcanic eruptions helped to form the rugged mountain landscape of the Galápagos Islands. The Galápagos are best known for their diverse array of plant and animal species. Many species are endemic, which means they are not found anywhere else in the world.
What is the Galapagos Islands function?
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 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 defines a biodiversity hotspot?
To be classified as a biodiversity hotspot, a region must have lost at least 70 percent of its original natural vegetation, usually due to human activity. There are over 30 recognized biodiversity hotspots in the world. The Andes Mountains Tropical Hotspot is the world’s most diverse hotspot.
