What specifically describes the balance between the lithrosphere floating atop the asthenosphere?
The balance between the lithosphere and asthenosphere is described by isostasy, which refers to the gravitational equilibrium between the Earth's crust (lithosphere) and the underlying mantle (asthenosphere). The lithosphere, being more rigid and less dense, floats on the semi-fluid asthenosphere, which allows it to adjust in response to changes in surface load, such as erosion or glaciation. This dynamic balance ensures that the lithosphere remains buoyant, maintaining stability in the Earth's topography over geological timescales.

What are tectonic plates floating on?
Tectonic plates are not floating; they are instead moving on the semi-fluid layer of the Earth's mantle known as the asthenosphere. The asthenosphere is a part of the upper mantle where rocks are partially molten, allowing the plates to move due to convection currents in the mantle.
What is the name for the principle that brings floating crust into gravitional balance?
The principle that brings floating crust into gravitational balance is called isostasy. It describes how the Earth's lithosphere (the rigid outer layer) maintains equilibrium by adjusting its thickness and elevation in response to changes in load, such as ice, water, or sediment. This balance is achieved through the buoyancy of the lithosphere as it "floats" on the denser, more fluid asthenosphere beneath it.
What are tectonic plates pushed by?
In the mantle, there is a fluid-like layer called the asthenosphere which has convection currents, due to the heat of the inner core. Earth's plates are hypothetically "floating" on the asthenosphere. The currents in this layer push whatever is on top of it, thus the continents move.
What is the name for the principle that brings floating crust into gravitational balanace?
The principle that brings floating crust into gravitational balance is called isostasy. This concept explains how the Earth's lithosphere, or outermost layer, floats on the denser asthenosphere below, adjusting its elevation to maintain equilibrium.
What are the earths plates floating on?
The surface of the Earth is divided into roughly 30 separately distinct units called plates. Each individual plate is separated by a fault, and each plate moves independently of every other plate. The movement, or float, of the lithospheric plates is caused by heat from the Earth's interior, which causes convection currents in the Earth's mantle, a layer of solid but movable plastic-like rock. The movement of Earth's lithospheric plate which 'float' on the mantle is very slow in human terms, roughly the rate of fingernail growth, but over millions of years, the change in plate locations is dramatic.
What are the tectonic plates floating?
The continental plates float on asthenosphere, molten rock (lava).

They are floating on the outer core

What is the stress caused by in the Earth's crust?
The grinding of tectonic plates. This caused by the outer core sending heat to the asthenosphere. The heat creates convection cells (aka convection currents), which move the asthenosphere. The tectonic, or lithospheric, plates are floating on the asthenosphere. When the asthenosphere moves, the tectonic plates move, and they gring together. The grinding will eventually cause a tectonic plate to fracture, which releases energy through the earth as seismic waves, and an earthquake occurs.
Is it true or false that the asthenosphere floats on the lithosphere?
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
Soft layer of the mantle on which the lithosphere floats?
The soft layer of the mantle on which the lithosphere floats is called the asthenosphere. It is a partially molten layer that allows for the movement of tectonic plates due to its weak and ductile properties. The lithosphere, which is the rigid outer layer of the Earth, sits on top of the asthenosphere and moves due to the convection currents in the mantle beneath it.

On what layer do the crustal plates float?
Crustal plates float on the asthenosphere, which is a semi-fluid layer of the Earth's mantle just below the lithosphere. The movement of these plates is driven by the convection currents in the asthenosphere.
What is the general term of the up and down forces between the crust and the mantle?
Isostasy is the balance and buoyancy of the Earth's crust floating on the asthenosphere, the top layer of the mantle. The asthenosphere, like Silly Putty, adjusts to the different densities and thicknesses of the crust. For instance, glaciers add weight (density, really) to the surface of the Earth. The added density depresses the flexible crust down into the asthenosphere, which, in turn, responds by slowly flowing away from the added burden. As the glaciers melt, the crust under them rebounds (rises), and the asthenosphere flows back, returning to its normal level.
Where did the term float a horses teeth come from?
Floating is the medical term used to describe the rasping or filing of a horses' teeth. The term originated from the masonry term which describes the leveling of a row of bricks (floating).
