The weak part of the mantle is known as the asthenosphere. This layer lies beneath the lithosphere and extends from about 100 to 700 kilometers below the Earth's surface. The asthenosphere is characterized by its semi-fluid properties, allowing it to deform and flow slowly, which facilitates the movement of tectonic plates above it.
What else can I help you with?
Is the lithosphere a solid that floats on the inner part of the mantle?
Yes, the lithosphere is the rigid outer layer of the Earth that consists of the crust and the upper part of the mantle. It is broken into tectonic plates that float on the semi-fluid asthenosphere below.
Partially molten, plastic-like, flowing layer located below the solid part of Earths mantle?
Partially molten, plastic like, flowing layer located below the solid part of Earth's mantle is the Asthenosphere. The asthenosphere is mechanically weak and ductiley deforming region of the upper mantle.
What is the name of the soft weak layer of the mantle?
The soft, weak layer of the mantle is called the asthenosphere. It lies beneath the lithosphere and is composed of partially molten rock, allowing for the movement of tectonic plates. The asthenosphere plays a crucial role in geological processes, including plate tectonics and volcanic activity.
What is the hot weak part in the upper mantle?
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.
How is the lithosphere different then the adthosphere?
The lithosphere is defined as the crust plus the brittle, uppermost mantle to which it is attached. The part of the upper mantle called the asthenosphere is ductile, and is the portion of the mantle on which the lithosphere 'floats'. Essentially, it is a difference in the degree of ductility. The lithosphere is brittle; the mantle is ductile.
Is the mantle part of the asthenosphere?
Yes, the aesthenosphere is the part of the upper mantle that is highly viscous and mechanically weak behaving as a ductile solid.
What is the name of the lower part of mantle and the upper part of mantle?
The lower part of the mantle is called the "lower mantle" or "mesosphere", while the upper part of the mantle is referred to as the "upper mantle" or "asthenosphere".
What part of the mantle means weak layer and is in the semi-plastic state?
Asthenosphere
what word best describes the hot weak inner part of the upper mantle which can flow?
asthenosphere
Is the lithosphere a solid that floats on the inner part of the mantle?
Yes, the lithosphere is the rigid outer layer of the Earth that consists of the crust and the upper part of the mantle. It is broken into tectonic plates that float on the semi-fluid asthenosphere below.
Partially molten, plastic-like, flowing layer located below the solid part of Earths mantle?
Partially molten, plastic like, flowing layer located below the solid part of Earth's mantle is the Asthenosphere. The asthenosphere is mechanically weak and ductiley deforming region of the upper mantle.
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 the name of the central part of earth below mantle?
It is the inner core.
What are the part of the mantle?
The upper mantle and the lower mantle.
What is the name of the soft weak layer of the mantle?
The soft, weak layer of the mantle is called the asthenosphere. It lies beneath the lithosphere and is composed of partially molten rock, allowing for the movement of tectonic plates. The asthenosphere plays a crucial role in geological processes, including plate tectonics and volcanic activity.
Is lithosphere part of the mantle?
Yes, it is the top part of the Earth's mantle
Is lithosphere part of mantle?
Yes, it is the top part of the Earth's mantle
