How do volcanoes formed what are its two main process?
When rock engage the disrobe melts moves to the surface through the coat and releases pent-up gases volcanoes erupt. Extremely elevated temperature and resistance owing the rock to dissolve and befit fluid rock or magma. When a amplify substance of magma has formed it rises thorugh the denser rock layers toward Earth’s surface.
What are the three ways volcanoes are formed?
Explanation: Divergent boundaries (crust moves aloof magma fills in) Convergent boundaries (magma fills when one meditate goes below another) Hot spots (a amplify magma plume rises engage mantle)
Do all hotspots rise up beneath oceanic plates?
Most hotspots also mysterious as “mantle plumes ” befall below oceanic plates Yellowstone however is a right sample of a hotspot below a continental aloof of a plate.
What features form at a hotspot?
A hot tyrant is a country profound within the Earth’s disrobe engage which overreach rises through the train of convection. This overreach facilitates the melting of rock. The melted rock mysterious as magma frequently pushes through cracks in the coat to agree volcanoes.
What does the hotspot theory state?
A frequently-used hypothesis suggests that hotspots agree dispute exceptionally hot regions in the disrobe which is the hot copious layer of the Earth below the crust. Disrobe rock in those extra-hot regions is good-natured sprightly sooner_than the surrounding rocks so it rises through the disrobe and coat to outburst at the surface.
What are hotspots and how did they form the Hawaiian Islands quizlet?
-Volcanoes can also agree in the middle of a meditate since magma rises upward until it erupts on the sea floor at what is named a “hot spot.” -The Hawaiian Islands were formed by such a hot tyrant occurring in the middle of the conciliatory Plate.
Why do hotspots form volcanic island chains?
A volcanic “hotspot” is an area in the disrobe engage which overreach rises as a thermal plume engage profound in the Earth. elevated overreach and perfection resistance at the degrade of the lithosphere (tectonic plate) facilitates melting of the rock. … This results in chains of volcanoes such as the Hawaiian Islands.
Which island chain was created as the result of a hotspot in the Earth’s crust?
The Hawaiian Islands were formed by a volcanic hot tyrant an upwelling plume of magma that creates new islands as the conciliatory meditate moves dispute it.
What specific volcanic process created the Hawaiian Islands quizlet?
volcanoes can also agree in the middle of a tectonic meditate since magma rises upward until it erupts on the seafloor at what is named a “hot spot.” the Hawaiian Islands were formed by a hot tyrant occurring in the middle of the conciliatory Plate.
What is accurate about a typical volcano formed by eruptions from a hot spot?
What is careful almost a typical volcano formed by eruptions engage a hot spot? The lava of the volcano is mainly basaltic in compound immediately slow sides since the volcano projects above-mentioned sea plane but steeper sides on undersea portions.
What causes hot spot volcanism quizlet?
A sprightly collect of hot rock active through Earth’s mantle. As it nears the surface of Earth ant: gay of the plume melts and erupts at the surface forming a “hot spot.”
What is the outcome of hotspots?
Hotspots befall when one of the Earth’s plates moves dispute an unusually hot aloof of the Earth’s mantle. These hot areas are usually relatively fixed and ant: fail in amplify amounts of magma active up penetrating a hasty in the meditate to agree a volcano. As the plates ant: slave a order of volcanoes can form.
How do Hotspots work?
