What is the melted material beneath the Earth's surface?
This material is most often referred to as magma.
What happens in a volcano?
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 are effects of connection currents in the mantle?
The flow of mantle effects convection currents in the mantle. This process happens as hot material within the mantle begins to rise. As it rises, it begins to cool and then sinks. This process repeats as a cycle of convection currents.
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.
What happens when buoyant mantle material gets near earths surface?
The buoyant mantle material will not subduct under Earth's continental crust. Instead, it will form mountains.
What brings material from the mantle to the earths surface?
What brings material from the Mantle to the Earth's Surface is rock...
What happens when water is added to rock in the mantle?
It causes a lowering of the melting temperature of the material, which in turn can cause partial melting of the mantle material leading to the formation of magma.
What is Circular movement of material inside Earth's mantle called?
What happens in the asthenosphere (part of the mantle) is called convection currents
What is the melted material beneath the Earth's surface?

The balance between the weight of a continent and the buoyant force of mantle is?
isostasy
What happens the the temperature and density of material between points D and A?
Because its closer to the mantle and the core.
What happens in a volcano?
How do convergent boundaries add material to earths surface?
At convergent boundaries some mantle material can melt and rise through the crust, forming volcanoes.
