What percentage is the mantel of the earth mass?
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).
How are lithosphere and the crust the same and different?
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.
Which of earth's layers contains soft areas on which plates float?
Earth's surface I might be wrong I am only 9
Area in the Earth's mantle hot enough to melt rock into magma and create volcanoes?
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.
What features would not form on earth's surface if the mantle were solid rock?
Any surface feature that had to do with lithospheric plate movements, such as a mountain, mountain chain, or subduction volcano.
A mantle plume extended up to the surface where There is?
Hot Spot
Why are most Hawaiian volcanoes nonactive?
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.
Canary Islands Hot Spot?
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.
What is mantle?
It is the second layer of the earth... That i am trying to figure out what it is composed o help me...

How does a hot spot make a chain of volcano mountains?
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.
Where does the lithosphere located?
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.
How are the lithosphere and the crust the same?
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.
What layer makes up most of the earths volume?
ANSWER: The crust floats on the asthenospheric mantle, which is convecting due to the forces of plate tectonics. The mantle, which extends to a depth of nearly 3,000 kilometers is the source of all magma. The mantle makes up 84% of the earth's volume and can sometimes get as hot as 3700°C. ==== ====
How was Honolulu formed?
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.

What is the ridge layer of earths surface made up of the crust and part of the mantle called?
