In seafloor spreading molten material rises from the mantle and erupts?
When spreading molten material rises from the mantle in the sea-floor and erupts, it can create sea mounts, which are underwater mountains. If enough material is ejected, the mounts will break through the surface of the water to create islands.
What happens to the old oceanic crust as new molten material rises from the mantle?
The older oceanic crust moves away from the spreading center and is eventualy subducted back into the mantle.
When does an active volcano erupt?
They can erupt anytime, when magma rises from the mantle and spews out of the volcano.
Why do you usually find volcanoes near subduction zones?
When one plate slides beneath another it carries volatiles such as water with it. These substances get into the mantle rock and lower the temperature needed for it to melt. This molten material then rises as it is less dense and forms volcanoes as it reaches the surface.
How is lava produced in a volcano and what is it made of?
The when it is inside the earth, the lava is called magma. It is composed of molten rock. It originates from the melting of rock in the mantle and the crust. How the material melts depends on the geologic setting. At divergent plate boundaries the crust becomes thinner, which reduces pressure on the mantle and lowers the melting point, causing some of it to melt. At subduction zones, volatile components such as water are introduced into the mantle, which also lowers the melting point. At hot spots, material rises from the hotter lower mantle to the upper mantle, and thus experiences lower pressure. The magma then rises through the crust to erupt from volcanoes. As the magma rises it sometimes melts some of the crust. Since some of the original magma solidifies this does not increase the total amount of magma but it is important in that it alters the magma's composition and thus its behavior.

In sea-floor spreading molten material rises from the mantle and erupts .?
When spreading molten material rises from the mantle in the sea-floor and erupts, it can create sea mounts, which are underwater mountains. If enough material is ejected, the mounts will break through the surface of the water to create islands.
What caused the plates to move?
The intense heat in the Earth's core causes molten rock in Earth's mantle to shift. That causes a pattern called a convection cell which forms when material rises, cools, and sinks. When the material sinks, it is warmed and rises again.
What happens to old oceanic crust as new molten material rises to the mantle?
The older oceanic crust moves away from the spreading center and is eventualy subducted back into the mantle.

Is the molten rock from the mantle that rises up the vent and flows out of a volcano?
yes. :)
In sea-floor spreading what happens to the old oceanic crust as new molten material rises from the mantle?
It gets pushed out to either side of the mid-ocean ridge.
What is a volcanic area on a plate where plume of mantle material rises?
Mantle plum

Melted material that rises from the mantle is called?
magma
Which layer of earth is the source of molten rock called magma that sometimes rises to earths surface?
the mantle
