hot spot
Hope this help
Hot Spot
The mantle makes up 68.4 % of earth's mass and 49.5 % of earth's volume. The mantle extends from the base of the crust to a depth of about 2900 km (1800 mi).
The lithosphere is made up of the crust and the upper mantle. On average the lithosphere extends about 100 km into the Earth's interior.
Earth's surface I might be wrong I am only 9
All of the Earth's mantle is hot. And while some geologists believe that there are Mantle plumes (or hot spots) current evidence seems to support a view that mantle plumes do not exist. What causes magma to rise up from the lower crust and mantle is the convection of the mantle and therefore the places where most heat (and magma) is coming up to the surface is along the mid oceanic ridges.
Any surface feature that had to do with lithospheric plate movements, such as a mountain, mountain chain, or subduction volcano.
Hot Spot
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 Canary hotspot is an area located just off of the northwestern coast of Africa within the Canary Islands. This is made up of a volcanic hotspot that has an underlying mantle plume that is considered to be quite deep under the earthâ??s surface.
It is the second layer of the earth... That i am trying to figure out what it is composed o help me...
Rift zone
A hot spot deep in the Earth's mantle creates a rising plume of magma that is even hotter than the regular magma of which the mantle is composed. When this plume of magma hits the crust, it breaks through and causes a volcano. The reason why we eventually wind up with a whole chain of volcanoes, rather than just one, is continental drift. The Earth's crust is moving, while the plume of magma is always directed at the same spot, so as the tectonic plate slowly drifts by, the plume will impact different parts of that plate.

The lithosphere is the hard rocky outer shell of the Earth, composed of the crust and uppermost mantle, that extends from the surface to a depth of up to 200 km at its deepest point.

The Hawaiian islands are the result of a hot spot beneath the Pacific Plate. Hot material rises from deep within the mantle and collects beneath the lithosphere. Some of it rises through the crust and erupts at the surface, forming volcanoes. Those volcanoes gradually build up into islands. As the plate moves over the hot spot the old volcanoes go extinct and new ones form.
