It is colder than the lower mantle.
What else can I help you with?
What is the special features of the mantle?
It is colder than the lower mantle.
What are the features of crust mantle and core?
the crust is dirt, the mantle is lava and the core is liquid and or solid metal
Where do convection currents flow in Earth?
Convection currents flow in Earth's mantle, which is the layer of rock beneath the Earth's crust. These currents are responsible for the movement of tectonic plates and the formation of features like mountain ranges, volcanoes, and earthquakes.
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.
What are the main features of the Earth's mantle?
The Earth's mantle is a layer of hot, solid rock between the crust and the core. It is composed of silicate minerals rich in iron and magnesium, and is responsible for convection currents that drive plate tectonics. The mantle's temperature and pressure conditions vary with depth, with the upper mantle being cooler and more rigid compared to the lower mantle.
What are columns of hot rock rising through earth's mantle called?
Columns of hot rock rising through Earth's mantle are called mantle plumes. These plumes originate near the core-mantle boundary and can cause volcanic activity on the Earth's surface when they reach the crust, creating features like hotspot volcanoes.
What is covecting mantle?
Covecting mantle refers to the dynamic movement of material within Earth's mantle. This convection is driven by the internal heat of the Earth, causing the mantle material to slowly rise, cool, and sink in a circular pattern. These movements play a significant role in processes such as plate tectonics and the creation of geological features on the Earth's surface.
What is mantle plume?
A mantle plume is a column of hot rock rising from deep within the Earth's mantle to the surface. These plumes can cause volcanic activity and create features like hotspots and mid-ocean ridges. Mantle plumes are thought to be responsible for some of the most significant geological phenomena on Earth.
What is a hot plume of mantle material which may extend to the core mantle boundary produces a?
A hot plume of mantle material, which may extend to extend to the core-mantle boundary, produces a(n) a volcanic region a few hundred kilometers across
What are the four parts of the mantle from top to bottom?
The mantle is divided into four main parts from top to bottom: the uppermost mantle, which includes the lithosphere and asthenosphere; the transition zone; the lower mantle; and the outer core. The uppermost mantle is solid and rigid, while the asthenosphere is semi-fluid and allows for tectonic plate movement. The transition zone, located between the upper and lower mantle, features changes in mineral structures due to increased pressure. The lower mantle is solid and extends to the outer core, characterized by higher temperatures and pressures.
How do you spell asthonshpere?
The correct spelling is "asthenosphere" -- the ductile upper layer of the Earth's mantle over which the crustal features or lithosphere moves.
What are the features of the lithosphere?
The lithosphere is the outermost shell of a rocky planet. On Earth, it is the crust and the upper mantle of the planet, containing the tectonic plates.
