where do lava comes from, what are the forces that make it travel through the crust, and what are the channels it uses to reach the surface? please

lava comes from volcanos.

It occurs when the earth takes a crap

Lava comes from underneath the Earth's crust. Most of the Earth is very hot and molten, only the top is solid and cool and okay for life and liquid water and so on. Sometimes pressure under the surface pushes the magma around, and with nowhere else to go it squirts up through the crust and comes out in the form of a volcano.

Magma is molten igneous rock which has gone through a lot of warm temperature to soften the unique rock. The magma is kept in the Earth's mantle, this also strikes plate barriers. The magma is kept in magma chambers which run by a volcano as a lot because the crater (undemanding as a universal vent) or can "strengthen" to the area. The magma erupts as lava by volcanic pastime or basically by ability of plate tectonics. The lava composition is going from extremely undemanding to acidic relying on how a lot silica is in the rocks. If there is low silica <40% the lava is stick and thick so thats the lava you've a tendency to work out. If the silica content fabric is >sixty 3% the volcano is explosive and that's the position you get pyroclastic flows. As on your idea, no that's not plausible because the magma is formed in the mantle and not in any respect on the crater.

lava is encrusted deep into the surface of the earth. below the core.volanoes are holes that were already there years ago and lava accumulated there.making the other lava travel towards the greatest amount of concentration in lava thus storing all that lava inside a volcano.when the temperature reaches its maximum level of heat it (just like when you boil water) it erupts.

The earth is like a water balloon full of molten rock instead of water. When there is a crack in the crust, just like the water balloon when it has a leak, the molten rock will come out.

Lava is molten rock expelled by a volcano during an eruption.

Volcano's.The pressure way,down in the core of the volcano.It gets very,very hot!And the pressure forces its way up.Then BOOM,it has to come out somewhere.
