A hot spot. An example of a hot spot are the islands in Hawaii which were made from hot spots.
in the mantle above the slab
The layer that floats above the Earth's core is the mantle. The mantle is a thick layer of solid rock that lies between the core and the Earth's crust. It is responsible for the movement of tectonic plates and plays a crucial role in Earth's geology.
Depends if your talking about the inner core or the outer core: Outer core or mantle.
The middle mantle is just above the lower mantle.
The Hawian island chain was created by a "hotspot" in the Earth's mantle. This in turn is thought to be caused by a mantle plume. This is an up welling of very hot material from deep within the mantle (possibly even the core mantle boundary). The mantle plume stays in the same place, however the lithospheric plates are moving above it. So the mantle plume causes volcanism to occur at the spot on the surface directly above it forming a volcano, however as that volcano is dragged away by the movement of the lithospheric plate it is no longer over the mantle hot spot and loses it's supply of magma and becomes extinct. Meanwhile a new volcano will form in the lithosphere that is currently over the hotspot.
the center of the earth is called the inner core then you have the outer core and then you have the mantle and lastly the earths crust
im pretty sure it earths crust and core or if not the top part of the mantle and the crust above it this is the only infomation i could get sorry
Convection cells in the Earth's mantle can drive the movement of tectonic plates, which in turn can affect the Earth's crust through processes like subduction, where one plate is forced beneath another. This movement can cause earthquakes, volcanic activity, and the formation of mountain ranges as plates collide or separate.
The very top of Earth's mantle is known as the lithosphere. It is a rigid layer that consists of both the uppermost part of the mantle and the crust above it. The lithosphere is broken into tectonic plates that float on the semi-fluid asthenosphere beneath it.
is the temperature if the stiffer mantle above or below its melting point
The mantle makes up about 67% of Earth's mass. It is a layer of hot, dense rock located beneath the Earth's crust and above the core. The mantle plays a crucial role in the movement of Earth's tectonic plates.
The Earth's crust lies above the mantle.
