The lower boundary of the asthenosphere is not well defined. It lies below the lithosphere and above the lower mantle and outer core. It usually lies at depths of 80-200 km but can range as deep as 700 km.
The transition zone between the asthenosphere and the crust is called the lithosphere. It is the rigid outer layer of the Earth that consists of the crust and the uppermost part of the mantle. The lithosphere is broken into tectonic plates that float and move on the semi-fluid asthenosphere beneath it.
The asthenosphere.
Tectonic plates float on the asthenosphere, which is a semi-liquid layer of the Earth's upper mantle. The movement of these plates is driven by convection currents in the asthenosphere.
The five structural zones of Earth are the inner core, outer core, mantle, asthenosphere, and lithosphere. Each zone has distinct physical and chemical properties that contribute to the structure and behavior of Earth's interior.
The plates of lithosphere float on top of the semi-fluid asthenosphere, which is located beneath the lithosphere in the Earth's upper mantle. The asthenosphere allows the plates to move and interact with each other due to its partially molten and more ductile nature compared to the lithosphere above it.

The plasticlike layer of Earth is the asthenosphere. It is a zone of the upper mantle where rock is soft and capable of gradual flow. The lithospheric plates float and move on top of the asthenosphere, contributing to the movement of tectonic plates.
The transition zone between the asthenosphere and the crust is called the lithosphere. It is the rigid outer layer of the Earth that consists of the crust and the uppermost part of the mantle. The lithosphere is broken into tectonic plates that float and move on the semi-fluid asthenosphere beneath it.
The rigid zone above the asthenosphere that includes the crust and upper mantle is called the lithosphere. This layer is divided into tectonic plates that float on the semi-fluid asthenosphere and move due to the convection currents beneath them.

Tectonic plates float on the asthenosphere, which is a semi-liquid layer of the Earth's upper mantle. The movement of these plates is driven by convection currents in the asthenosphere.
The tectonic plates float on the lithosphere. This overlies the asthenosphere.
No. The asthenosphere is a ductile layer of the mantle that tectonic plates float on top of.
