What else can I help you with?
Are mines deep enough to reach the mantle?
No, mines are not deep enough to reach the Earth's mantle. The Earth's mantle is located about 25 miles beneath the Earth's surface, while most mines only reach depths of a few miles.
What are plumes of molten rock originating deep within the mantle known as?
Plumes of molten rock originating deep within the mantle are known as mantle plumes. These plumes are believed to be responsible for hotspots and volcanic activity at the Earth's surface.
Is the deep mantle mostly solid?
Of course.
The deep mantle is composed of material with a lighter density than the outer mantle?
The deep mantle is actually composed of denser materials compared to the outer mantle. These denser materials are mainly made up of silicate minerals rich in iron and magnesium, which contribute to the overall density of the deep mantle. This density variation plays a key role in the movement of material within the Earth's mantle through processes like convection.
Topographic highs in the crust have deep what that extend into the mantle and provide buoyant support?
Topographic highs in the crust have deep roots that extend into the mantle and provide buoyant support through isostasy. These roots are a result of the difference in density between the crust and underlying mantle, allowing for uplifted regions to be supported by the denser mantle material beneath.
Are mines deep enough to reach the mantle?
No, mines are not deep enough to reach the Earth's mantle. The Earth's mantle is located about 25 miles beneath the Earth's surface, while most mines only reach depths of a few miles.
Is solid rock located deep in the mantle called magma?
No, solid rock located deep in the mantle is not called magma. Magma is molten rock that is found beneath the Earth's surface in the mantle and crust. Solid rock in the mantle is known as the lithosphere.
What are plumes of molten rock originating deep within the mantle known as?
Plumes of molten rock originating deep within the mantle are known as mantle plumes. These plumes are believed to be responsible for hotspots and volcanic activity at the Earth's surface.
Is the deep mantle mostly solid?
Of course.
how many km deep is the earths mantle?
2900 km
At deep ocean trenches what allows oceanic crust to sink back into the mantle?
Conduction. Heat istransferred from the mantle to the crust, melting it to become part of the mantle.
How deep can you dig before reaching the Earth's mantle?
It is not possible to dig deep enough to reach the Earth's mantle because the mantle is located about 1,800 miles below the Earth's surface, much deeper than any human-made hole.
The deep mantle is composed of material with a lighter density than the outer mantle?
The deep mantle is actually composed of denser materials compared to the outer mantle.

Oceanic crust returns to the mantle at deep ocean trenches which are?
rocks
What is a energy source for hydrothermal vent?
The heat from deep in the earth's mantle.
Topographic highs in the crust have deep what that extend into the mantle and provide buoyant support?
Topographic highs in the crust have deep roots that extend into the mantle and provide buoyant support through isostasy. These roots are a result of the difference in density between the crust and underlying mantle, allowing for uplifted regions to be supported by the denser mantle material beneath.
What is is the thickness of the upper mantle?
In oceanic areas the upper mantle is usually 5-200km thick and on continental areas it is 75-300km deep.
