from being under the mantle the gas pressure builds up and forces magma out forming a hot spot.
What else can I help you with?
What processes found at hot spots will help igneous rock form?
Igneous rocks are formed around hot spots when there is an increase in temperature, a decrease in pressure, or a change in composition. Igneous rock is formed through the cooling and solidification of magma or lava.
When mountains are formed such as by uplift or hot spots away from a convergence they are called?
Mid-plate.
Are hot spots located over rising calderas?
No. Hot spots are located under many, but not most volcanoes. Many calderas are associated with subduction zones. When the ground in a caldera rises it is called a resurgent dome, not a hot spot.
What kind of rock types are found in hot spots?
Hot spots are known to produce basaltic rocks, such as basalt and rhyolite. These rocks are typically associated with volcanic activity and are formed from the cooling and solidification of magma from the Earth's mantle. The specific rock type found in hot spots can vary depending on the composition of the magma and the conditions of the eruption.
What boundary is it when a volcano formed?
Volcanoes can form at convergent boundaries, divergent boundaries, and at hot spots away from any plate boundary.
What are the volcano prone areas of the world?
There are many areas around the world where volcanoes reside. Most volcanoes are near plate boundaries (see "what are tectonic plates?") because this is where lava from the mantle is forced upward, to the surface. Volcanoes formed in the middle of plates are formed from "hot spots", regions where hot rock and magma are forced to the surface from deep in the mantle in tube-like formations. As plates slide across these hot spots, lines of volcanoes are formed.
What are the major volcanic hot spots?
Major volcanic hot spots include the Hawaiian Islands, which are formed by a plume of molten rock beneath the Pacific Plate, and Yellowstone in the United States, known for its supervolcanic activity. Other notable hot spots include the Galápagos Islands, Iceland, and the Réunion Island in the Indian Ocean. These hot spots are characterized by volcanic activity that occurs independent of tectonic plate boundaries, often resulting in the formation of islands and extensive volcanic landscapes.
Why hot spots located at the tropical regions?
They aren't necessarily. Several well-known hot spots are in tropical areas, but a number are not. We have the Hawaiian and Galapagos hot spots, but we also have hot spots under Yellowstone, Iceland, and Antarctica.
Where do hot spots start?
hot spots begin at the boundary between the mantle and the outercore.
Where do hot spots originate?
Hot spots begin at where 2 plates move apart
What type of volcanoes form on a hot spot?
Shield volcanoes typically form on hot spots. These volcanoes have gentle slopes due to the low-viscosity basaltic lava they produce. Examples of shield volcanoes formed on hot spots include Mauna Loa in Hawaii and Galapagos Islands in Ecuador.
What causes hot spots on earth?
The flow of molten magma is what causes varying hot spots on Earth. Hot spots are also known to heat water beneath the ground.
