Earth's mantle is a rocky shell about 2,890 km (1,800 mi) thick that constitutes about 84 percent of Earth's volume. Two main zones are distinguished in the upper mantle: the inner asthenosphere composed of flowing rock in the state of plasticity, about 200 km thick, and the lowermost part of the lithosphere, composed of rigid rock, about 50 to 120 km thick. A thin crust, the upper part of the lithosphere, surrounds the mantle and is about 5 to 75 km thick. The mantle is divided into sections which are based upon results from seismology. These layers (and their depths) are the following: the upper mantle (starting at the Moho, or base of the crust around 7 to 35 km, downward to 410 km), the transition zone (410-660 km), the lower mantle (660-2891 km), and in the bottom of the latter region there is the anomalous D" layer with a variable thickness (on average ~200 km thick)
What else can I help you with?
What will happen if the flow of hot rock in earths mantle if the planets core eventually cools?
The flow of hot rock in earths mantle will stop and Earth's magnetic field will disappear
How does hot spot form?
A hot spot is formed on a point of the earths surface where strong upward convection currents or plumes of hot magma in the upper mantle push up below the plates of the lithosphere causing volcanic activity. no it doesn'twhen the mantle is weak
What are the Hot rocks rising in the mantle called?
The hot rocks rising in the mantle are commonly referred to as "mantle plumes." These are columns of hot, solid material that rise from deep within the Earth's mantle, potentially leading to volcanic activity when they reach the crust. Mantle plumes can create hotspots, which are areas of intense volcanic activity, like those seen in Hawaii.
What is the circulation within earths mantle called?
The circulation within Earth's mantle is called mantle convection. This process involves the movement of hot material rising and cool material sinking in the mantle, creating convection currents that drive plate tectonics.
What are facts about earths upper mantle?
Temperature is about 2000 to 3000 degrees celsius maybe less.The mantle is hot but not the hottest layer.It is is the second layer of the Earth. The mantle is the thickest layer of the earth, it is the layer of the earth beneath the crust.Upper mantle and Lower mantle are the two parts of the mantle, The lower mantle is deeper and denser than the upper mantle .
How is the mixture of cornstarch and water different from the Earths Mantle?
the earths mantle is very hot were cornstarch is not hot at all
How is the mixture of cornstarch and water differ from the earths mantle?
the earths mantle is very hot were cornstarch is not hot at all
Is it hot in the earths mantle?
Decay of radioactive elements in the mantle heats it.

Is the earths lower mantle hot?
the average temperature for the Earth's lower mantle is 5400 degrees
Where is a region where hot rocks extend from deep within the mantle?
a hot spot :)
What Layer of hot and solid material between the crust and Earths core?
It is the Mantle.
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 is an adjective that describes the mantle?
Adjectives would include deep, shallow, hot, moving, or dense.
