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
No. The Asthenosphere is the layer below the Lithosphere within the Earth.
No. The lithosphere, which is the solid crust we live on, is thought to float on top of the asthenosphere.
The asthenosphere isbelow the lithosphere, so in other words you were correct.
yes, exactly. On top of the mantle, right below the crust
No. The lithosphere moves over the asthenosphere.
Yes it does.
False
yes
false
True
Yes; at divergent/constructive boundaries, plates move apart and new oceanic lithosphere forms.
False - the asthenosphere is a solid that deforms in a ductile fashion - it undergoes permanent plastic deformations. Further information: The statement must be false. Plastic is a solid, so if something is going to be considered a non-solid, it cannot be like a solid. Whether or not the asthenosphere is solid, one cannot argue that it is non-solid as a result of it having a characteristic of plastic.
The asthenosphere (or low-velocity zone) is believed to be about 200 kilometers (120 miles) thick. The layers of rock that make up the asthenosphere are thought to be partially melted and hotter than those in the lithosphere. If this were true, it would explain why the asthenosphere might also have less surface integrity, making it a possible source for the generation of new magma.
false
False. It forms in the Athenosphere!!
False.
True
Yes; at divergent/constructive boundaries, plates move apart and new oceanic lithosphere forms.
Oil floats on water because water is denser than oil.
Convection current occurs due to the difference in densities

I have the same question but its false it in my course 2 science textbook. I hope this helps and i dont know what forces plates along faults in earths lithosphere sorry!
False
The Earth's asthenosphere starts at depths of around 100 to 200 km below the surface and extends down to around 700 km. This is part of the upper mantle.Directly below the lithosphere. The asthenosphere is located between 100-350 km below the surface of the Earth. The Asthenosphere is a ductile yet solid layer located inthe upper mantle.in the upper mantle
