Volcanoes allow the molten lava from the outer core to pass through weak spots in the mantle.
Scientists know the outer core is liquid because S waves, which cannot travel through liquid, are not detected beyond the core. Additionally, seismic waves from earthquakes have shown that P waves slow down significantly when passing through the outer core, indicating it is a liquid layer.

some kinds of seismic waves cannot travel through liquids, such as the outer core.

Seismic measurements and rheology. The outer core is so hot the iron and nickel there is liquid. The inner core is also as hot and just as liquid but the pressure in the inner core is so great it is solid. Some believe the inner core is a single iron crystal from earth's initial formation but there is no evidence to support that.
the outer core is above earths solid inner core and below its mantle this is the outer part but not the crust and it would feel pretty warm to go through this area. ok well i hope this helped this is all i know.!:)

Oh, dude, the inner mantle is definitely hotter than the outer mantle. Like, we're talking about temperatures reaching up to 4000°C in the inner mantle compared to a measly 500-900°C in the outer mantle. So, if you're looking for a hot spot, the inner mantle is where it's at.
The inner core is solid, but the mantle is the only layer of Earth that flows in currents. These currents are caused by convection. If you don't know what convection is then you might as well look it up because I don't have a good definition.
Scientists determined that the Earth's outer core is liquid primarily through the study of seismic waves generated by earthquakes. When these waves travel through the Earth, they behave differently depending on the state of the material they encounter. S-waves, which cannot travel through liquids, are absent in the outer core, indicating that it must be in a liquid state. Additionally, the behavior of P-waves, which can travel through both solids and liquids, further supports the conclusion that the outer core is liquid.
Scientists study seismic waves and magnetic fields to determine the composition and properties of Earth's core. They use data from earthquakes and magnetic measurements to infer that the inner core is solid iron and nickel, while the outer core is liquid iron-nickel alloy. Deep drilling and experimental simulations also provide insights into the Earth's core composition.
nope i dont know really
