What is an hot spot?
A hot spot is an area on Earth over a mantle plume or an area under the rocky outer layer of Earth, called the crust, where magma is hotter than surrounding magma. The magma plume causes melting and thinning of the rocky crust and widespread volcanic activity.
Is a classic example of a hot spot?
Question: Activity 1.5: HOT SPOTS A classic example of a hot spot is the Hawaiian Islands where only one island has active volcanoes. Hot spots are the surface manifestations of a mantle plume, which are vertical movements of heat through the mantle.
Where are hot spots found?
Hot spots are found around the globe, on land and in the ocean. The Hawaiian Islands are the youngest volcanic mountains in a long chain of volcanoes that formed over a hotspot. They are still forming today.
What is a hot spot and how does it work?
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.
Is Yellowstone a hotspot volcano?
The Yellowstone hotspot is a volcanic hotspot in the United States responsible for large scale volcanism in Idaho, Montana, Nevada, Oregon, and Wyoming, formed as the North American tectonic plate moved over it. The hotspot currently lies under the Yellowstone Caldera.
Why is Yellowstone a hotspot?
Beneath Yellowstone National Park in the western United States, lies a hot, upwelling plume of mantle. Heat from the mantle melts the overlying rocks and the resulting magma pools close to Earth’s surface. Areas such as these are known as volcanic hotspots. Occasionally, molten rock from a hotspot will erupt.
What is the most famous hot spot?
Although Hawaii is perhaps the best known hotspot, others are thought to exist beneath the oceans and continents. More than a hundred hotspots beneath the Earth’s crust have been active during the past 10 million years.
