How do you know earths outer core is liquid?
Volcanoes allow the molten lava from the outer core to pass through weak spots in the mantle.
Where does the lava emitted during volcanic eruption come from?
Magma originates either from rising plumes of heat at hot spots in the Earth's mantle, where decompression melting takes place as the hot rock nears the surface; or, it originates in the mantle from subduction of oceanic crust, where cold, wet rock speeds melting of the subducting rock and it rises toward the surface.Read more: Where_does_magma_and_lava_come_from
What heats the lava in a volcano?
The lava of a volcano originates from Earth's mantle, which is very hot due to a combination of radioactive decay and residual heat from Earth's formation.
How are lava form?
Lava is molten rock. The rock deep inside the earths mantle is always molten, and when it occasionally breaks through to the surface, the opening is called a volcano, and the liquid rock spilling out of the top is lava.
What kind of landforms are made by volcanoes?
It when plates colliding and making the volcanos also when the earths crust is open and the mantle or lava comes out,
What is upon the sky and what is under the land?
upon the sky is heaven is higher. under land is the earths crust,mantle and then pure lava.
What is earths mantle heated by?
Earth's mantle is mainly heated by the decay of radioactive isotopes and residual heat from the formation of the planet. This heat causes convection currents in the mantle which drive plate tectonics and other geological processes.
Does the magma and lava from a volcano come from the mantle?
Yes it does , The magma finds gaps through the crust ( oceanic or continental) and comes up as a volcano. It is originally in the mantle.
What is melted in a volcano?
mama also known as lava it's melted rock and other things and is from the earths mantle located under the crust
Where does molten rocks come from?
It comes from the melting of material within the Earth's mantle. Moltan Rock comes from the lava chambers, the temperature makes the bits of sedimaentary and igneouse rock wich is made into lava , all the time this takes place in the earths inner third the mantle.
What is a liquid rock called?
That depends where it is. On the surface of the planet it would be lava and in the earths core it would be the mantle.
What does the mantle make?
Lava
