The hot, weak part of the upper mantle is known as the asthenosphere. This region lies beneath the lithosphere and is characterized by partially molten rock that allows for slow, convective movement. The increased temperature and pressure in the asthenosphere reduce its viscosity, enabling the tectonic plates of the lithosphere to move over it. This dynamic behavior plays a crucial role in plate tectonics and geological processes.
What else can I help you with?
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 is the hot weak zone found within the upper mantle?
The hot weak zone found within the upper mantle is known as the asthenosphere. It is characterized by high temperatures and partial melting, resulting in a layer of partially molten rock material that allows the lithospheric plates to move gradually over time. The asthenosphere plays a critical role in plate tectonics and the movement of Earth's crustal plates.
What is the state of matter of the Earth's upper mantle?
The Earth's upper mantle is composed of solid rock that flows through liquid rock, also known as lava.
Which layer is composed of solid rocks and hot molten rock?
The solid rocks and hot molten rock are found in the Earth's lithosphere, which includes the crust and upper part of the mantle. This layer is known for its rigid properties and is divided into tectonic plates that interact with each other. The molten rock, or magma, can also be found in the asthenosphere, a partially molten region of the upper mantle.
Is magma found in the upper mantle?
I.am not sure but i think it is bc i believe the upper mantel is extremely hot
what word best describes the hot weak inner part of the upper mantle which can flow?
asthenosphere
What part of the earths mantle that flows and moves the plates of the earth?
Mantle plumes are in the mantle, BELOW the Earth's crust. The circulation of heat from the lower mantle to the upper mantle can cause "hot spots" in the overlying crust, heating the magma in the areas.

What happens when a weak part in the crust moves over a hot spot in the mantle?
It forms volcanoes and sometimes islands like Hawaii.
What is Earth's upper mantle?
The asthenosphere is the upper part of Earth's mantle. It is partially molten (plastic rheology) and mechanically detached from the lithosphere, which is mostly the Earth's crust (but also a little bit of upper mantle). The density of the upper mantle is your mom! (yo mamma!)
The part of the earth between the core and the crust?
The part of the Earth between the core and the crust is the mantle. It is a layer of hot, solid rock that surrounds the Earth's core. The mantle is responsible for movements of tectonic plates and is divided into the upper and lower mantle.
Is the mantle of Earth's layer liquid?
The upper part is thick and fudge like, and the lower part is more like liquid. It's all hot, molten rock.

What is a description of the earths upper mantle?
The upper layer of the Earth of how I'd describe is It's hot and is 1000 degrees
Is magma found in the upper mantle?
