A substance can't be rigid and molten. I wonder if you are confused by the lower mantle, also called the asthenosphere, which is not molten but can flow. In any case the layers are:

  1. The crust, which is solid rock and therefore rigid, though of course sufficient force will deform or fracture it.
  2. The mantle, which is essentially solid though the lower parts can flow much like asphalt under extreme pressure.
  3. The outer core, which is liquid iron and nickel.
  4. The inner core, which is solid iron and nickel.

What layer of the earth- that is rigid but molten?

The layer of the Earth that is rigid but molten is the asthenosphere. Located beneath the lithosphere, it is part of the upper mantle and is composed of partially molten rock that can flow slowly over time. This layer plays a crucial role in tectonic plate movement, allowing the more rigid lithosphere above it to move and shift.


What kind of sphere is the crust part of?

The Earth's crust is part of the lithosphere, which includes the crust and upper mantle. The lithosphere is a rigid layer that sits on top of the asthenosphere, a partially molten layer beneath it.


What is a soft layer of molten rock under the earths surface?

If there were such a thing it would not be soft, it would be liquid, and would be called magma. There really is no completely molten layer of Earth except for the outer core which is composed primarily of liquid iron along with some nickel and other trace elements.


Which layer of earth is thin rigid rock layer?

it is the crust because the crust is thin and rigid with rock


What layer of earth is made up of hot molten rocks?

The outer core is the only molten layer of the Earth. == ==


What is the rigid layer of earth surrounding the asthenosphere?

The rigid layer of Earth surrounding the asthenosphere is the lithosphere. It is composed of the crust and the upper portion of the mantle and is broken into tectonic plates that float on the semi-fluid asthenosphere below.


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.


What is the molten layer?

The molten layer refers to the outermost liquid layer found in the Earth's core. It is composed of molten iron and nickel, and it is responsible for generating the Earth's magnetic field through the movement of this liquid metal.


What is the rigid layer that includes the upper part of the mantle and the crust of the Earth?

The rigid layer that includes the upper part of the mantle and the crust of the Earth is called the lithosphere. This layer is divided into several tectonic plates that float on top of the partially molten asthenosphere below. The lithosphere is responsible for the movement of tectonic plates and the formation of geological features on Earth.


What is the rocky rigid layer of the earth?

The rocky rigid layer of the Earth is called the lithosphere. It consists of the crust and the uppermost part of the mantle and is divided into several tectonic plates that float on the semi-fluid asthenosphere beneath.


What layer of the earth is the least viscous?

The least viscous layer of the Earth is the outer core. It is composed mainly of molten iron and nickel, which gives it a lower viscosity compared to the solid inner core and the more rigid lithosphere.


What is the partially molten layer of earth called?

The partially molten layer of Earth is called the asthenosphere. It is located beneath the lithosphere and is responsible for the movement of tectonic plates.
