Yes it is very true. Due to enormous pressure build up by the volcanic material underground volcanoes are formed quickly. Mountains are formed slowly and gradually over a period of time and go on rising in inches and centimeters.
Because the keep eroding and eroding and mountains are sometimes made out of volcanos after they have erupted many times. take Hawaii for instance it was formed by a volcano.
because the tectonic plates converge and form mountains then the lava forms underground and erupts with burnin hot maga and lava
Volcanos CAN form under water. that is how land is formed.
Because of the plates
Some islands are formed by volcanoes, but most are not.
mostly on techtonic plates by volcanos
when to different plates push up to form a volcano
Volcanos and mountains cover most of japan
Composite volcanos commonly develop to form large volcanic mountains.
Because the keep eroding and eroding and mountains are sometimes made out of volcanos after they have erupted many times. take Hawaii for instance it was formed by a volcano.
plates of rocks beneath the earth's surface fold up and they have stones to help them since without them they will brake and form volcanos
Along rift valleys, lava pours out of cracks in the ocean floor, gradually building new mountains.
Volcanos form usually from thin spots in the Earth's crust where magma pipes may extend up to the surface. Magma flow may build up from these pipes resulting in the formation of volcanos. Also, plate tectonics may result in regions of upheval and the formation of mountains and volcanos.
they form by something
Hot spot volcanos. As these age they can become island chains and eventually subsurface seamount arcs if the hot spot is in the ocean.
