When lava goes threw crust it forms a hotspot (valcano)
Volcanoes are essentially holes in the earths surface through which magma and lava can erupt. when pressure builds up below the earths crust, magma is then forced violently out of the volcanoes.
volcanoes
volcanoes form when there is a crack in the earth's crust and a chamber of hot rocks(magma chamber) builds up pressure and eventually lava flows out of the crack
Some volcanoes lie over 'hot spots' in the Earth's mantle where molten material is continuously being produced and injected through the crust. Other types of volcanoes are produced from the subduction processes of tectonic plate collisions where magma pressure builds, erupts, then builds again in a cycle of sorts.
Volcanos are scientists window to the mantle and core past the crust. Or volcanoes erupt when pressure builds up then explodes!
because central places inn the united states not close to the ocean which builds up volcanoes by pushing them up on the ocean floor to form a volcano.
Nobody knows because volcanoes just erupt when the lava builds up and is forced up the main vent and out of the crater!
Well, according to scientific logic, extinct volcanoes can create new volccanoes because if they are in an area that can create more volcanoes and mountains like plate boundaries and hotspots, they can be joined with other newer landforms that grow around them. They can also use the pressure from their volcano to join with others so the pressure builds up.
the pressure builds up from tectonic plates moving past each other causing gaps and then volcanoes are produced. hope it helps.
The movement of plates cause volcanoes pressure builds in the mantle when 2 plates push towards together and the pressure pushes lava up through the ground and over time this makes volcanoes
inside the earth is gases and it gets very hot. this melts the rock and builds up pressure. Eventually it causes a volcanic eruption
When a volcano erupts and the lava hardens it can build up under water and over time, if enough builds up, the result will be an island
