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 else can I help you with?
What if mantle were rock what feature would not form on earths surface?
If anything is rock-solid, it will result in a flat landscape. This will mean that there will be no plateaus, deep sea trenches, volcanoes or mountains if the mantle were solid rock.
Which of the following is part of the Earths lithosphere SoilMagma None of these Mantle, magma, and soil Mantle?
Mantle is part of the Earth's lithosphere.
What is the motion of earths plates?
Slow and constant.
What is a special feature of earths crust?
One special feature of Earth's crust is that it is divided into tectonic plates that float and move on the semi-fluid upper mantle. This movement causes earthquakes, volcanoes, and the formation of mountain ranges.
The Mantle comprises what percentage of the earths mass?
The Mantle takes up 84% of the Earth's mass.
What causes volcanoes and earthquacks?
Volcanoes are caused by the rising of magma in the earths mantle and earthquakes are caused by the colliding of the earths tectonic plates against one another.
Convection currents in the earths crust causes volcanos?
No. Earth's crust does not convect. Convection in the mantle, however can create hot spots and rifting, which can lead tot he formation of volcanoes.
How does plate tectonics affect the mantle?
Tectonic Plates float on top of the earths mantle, the earths mantle is made up liquid which is always circulating.
What kind of landforms are made by volcanoes?
It when plates colliding and making the volcanos also when the earths crust is open and the mantle or lava comes out,
What is the composition earths mantle?
The mantle is 82% of Earth's volume. It is composed of ultramafic rock called peridotite, which is hot enough to flow.
What if mantle were rock what feature would not form on earths surface?
If anything is rock-solid, it will result in a flat landscape. This will mean that there will be no plateaus, deep sea trenches, volcanoes or mountains if the mantle were solid rock.
How do you know earths outer core is liquid?
Volcanoes allow the molten lava from the outer core to pass through weak spots in the mantle.
What name is given to the area where volcanoes often occurs because convection in the earths mantle produces a column of magma that rises into the crust?
hotspots
How are earthquakes eruptions different from volcanoes?
Earthquakes do not exactly erupt. Earthquakes are caused by the movement the Earth's tectonic plates. Yes, Earthquakes can contribute to the eruptions of Volcanoes because when one plate goes under the other water could be taken with it down into the Mantle. The water and sometimes air when is in the mantle is forced to find an exit and those exits are Volcanoes. When they go into the Volcano pressure builds up and the Volcano erupts. So really Earthquakes are caused by the movement of the Earths tectonic plates while Volcanoes are caused by a build up of pressure in the Earths Mantle.
How do convergent boundaries add material to earths surface?
At convergent boundaries some mantle material can melt and rise through the crust, forming volcanoes.
What is the name given to the area where volcanoes often occur because convection in the earths mantle produces a column of magma that rises into the crust?
hotspots
What help create volcanoes?
Volcanoes are created by the movement of tectonic plates on the Earth's surface. When two tectonic plates collide or move apart, magma from the mantle rises to the surface, eventually erupting through a volcano. Additionally, hotspots, subduction zones, and rift zones can also contribute to the formation of volcanoes.
