The top of the asthenosphere is closest to Earth's surface beneath mid-ocean ridges, where tectonic plates are moving apart. This is where the asthenosphere is pushed up towards the surface due to the divergent motion of the plates.
The top layer of soil, called the topsoil, is closest to the surface. It is the layer that contains most of the organic matter and nutrients needed for plant growth.
the Mesosphere
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 asthenosphere is the Earth's mechanical layer that is most easily deformed. It is a semi-fluid layer located in the upper mantle that allows the tectonic plates to move and slide on top of it. This deformation is what causes the movement and interaction of tectonic plates, leading to processes like earthquakes and volcanic activity.
Because of something called Isostacy-the gravitational equilibrium between lithosphere and asthenosphere, such that plates "float" at an elevation that dependes on the thickness and density. EX. Think floating ice cubes
Along a mid-ocean ridge
When hot magma reaches the top of the asthenosphere, it can erupt through the Earth's surface, leading to volcanic activity. This process can create new landforms, such as volcanoes, and release gases and lava onto the surface.

It is called the crust.
A Surface Wave.
The Earth's tectonic plates lay on top of the outer layer of the mantle. This layer is known as the asthenosphere.
The lithosphere sits on top of the asthenosphere.
The top layer of soil, called the topsoil, is closest to the surface. It is the layer that contains most of the organic matter and nutrients needed for plant growth.
No. The asthenosphere is a ductile layer of the mantle that tectonic plates float on top of.
The Asthenosphere is part of the Mantle of the Earth
Tectonic plates are segments of the lithosphere. They float on top of the asthenosphere.
A theory that says the lithosphere is divided into plates that move around on top of the asthenosphere is called '' plate tectonics''
