  • A volcanic "hotspot" is an area in the mantle from which heat rises as a thermal plume from deep in the Earth.

    Mantle Plume Debate

    High heat and lower pressure at the base of the. A hot spot is a region deep within the Earth's mantle from which heat Instead it occurs at abnormally hot centers known as mantle plumes. While most volcanoes form along tectonic plate boundaries, mantle plumes and hot spots lead to their development as well.

    Hot spot volcanoes.
    By plotting the data on a graph and fitting the data with a line of best fit, the plate velocity can be estimated by taking the slope of the line. Rating is available when the video has been rented.

    Tour photos Photos taken on our our tours. Natland, Is "hotspot" volcanism a consequence of plate tectonics? View Article. A third tectonic setting where volcanism occurs is called intraplate - or hot-spot -volcanism, which describes volcanic activity that occurs within tectonic plates and is generally NOT related to plate boundaries and plate movements. AGU 3, views.

    A new and active volcano develops over the hot spot, creating a continuous cycle of volcanism.

    Some hot spots produce volcanoes. Natland and D. As the tectonic plate moves over the stationary hot spot, the volcanoes are rafted away and new ones form in their place.

    Top Lists Recommended for you. Seismologists proposed some 30 years ago that stationary plumes of hot rock in the mantle occasionally punched through the crust to produce volcanoes, which, as the crust moved, generated island chains such as the Galapagos, Cape Verde and Canary islands.
