These volcanoes are made of pyroclastic material. These are small and only erupt for a short amount of time.
What is a cinder cone volcano

when tecnotic plates gets into water it makes the water seperate.
What happends when tecnotic plates get into water?

These locations of volcanoes gives clues about how volcanoes form on a map it may show some of the worlds most active volcanoes. a map may olso show the bounderies between tectonic plates.
where do volcanoes form?
100
lava that flows from undersea rift zones produces volcanoes and mountains chains called mid ocean ridges.
What happends when lava gets into water?
200
These volcanoes are made up of layers of lava released from repeated nonexplosive eruptions.
What is a shield volcano
200
these plates are areas where tectonic plates either collide, seperates, or slide on one another. at these bonderys it is possible for magma to form and travle to the surface. about 80 percent of active volcanoes on land form where plates collide. about 15 percent form where plates seperate.
What is tectonic plate bonderys?
200
Because magma is less dence than the surounding rock, it rises torward the surface, where it forms new crust on the ocean floor.
What is magma in water do?
300
shield volcanoes, composite volcanoes, cinder cone volcanoes.
What are three types of volcanoes
300
A convergent boundary is a place where tecnotic plates collide. when an oceanic plate collides with a continental plate, the oceanic plate usally slides underneatth the continental plate.
What happends when two tecnotic plates collide?
400
These volcanes are sometimes called stratovolcanoes, These are also one of the most common types of volcanoes
What is a composite volcano
500
around the centeral vent at the top of many volcanoes is a funnel shaped pit.
