The asthenosphere is more dense than the lithosphere.
Slab Pull Force occurs when a denser oceanic plate is forced beneath a less dense continental plate or oceanic plate in a process called subduction. It's the force caused by suction of the cold dense lithosphere into the asthenosphere at destructive margins. Basically, because lithosphere is denser than asthenosphere, there is gravitational imbalance which is passed on to the crust. this causes the lithosphere to be sucked inwards at the oceanic trenches into deep asthenosphere.
The lithosphere, asthenosphere, and mesosphere are all located within the Earth's upper mantle, which is part of the mantle layer. The lithosphere is the rigid outermost layer of the Earth, including the crust and uppermost mantle. The asthenosphere is a partially molten layer below the lithosphere, while the mesosphere is a solid layer beneath the asthenosphere.
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
The asthenosphere.
The asthenosphere is located in the upper mantle, just below the lithosphere. The lithosphere is the outermost layer of the Earth's crust that includes the rigid upper part of the mantle, while the asthenosphere is a semi-molten layer below the lithosphere that allows tectonic plates to move.

The layer directly under the Lithosphere is the Asthenosphere. The Asthenosphere is a semi-fluid layer of the Earth's mantle that allows for the movement of the tectonic plates above it. It is hotter and more ductile compared to the rigid Lithosphere.

Tectonic plates are segments of the lithosphere. They float on top of the asthenosphere.
