1. The ice represents the lithosphere. It "floats" on the punch as it is of lower density and therefore buoyant.

2. The ice is a brittle solid - this mechanical behaviour is similar to that displayed by lithospheric plates.

3. The punch behaves as a liquid and so can convect aiding the movement of the ice. To a certain extent so to does the asthenosphere (in actual fact, the asthenosphere is a highly ductile solid however it convects on a geological time-scale) .

How are the lithosphere and asthenosphere similar?

Both the lithosphere and asthenosphere are parts of Earth's uppermost layer, known as the Earth's crust. The lithosphere is the rigid outer layer made up of the crust and a part of the upper mantle, while the asthenosphere is a semi-fluid layer beneath the lithosphere. They are both involved in the movement of Earth's tectonic plates.


How can the continents float?

Tectonic plates are either oceanic crust and/or continental crust and the upper solid layer of the mantle. The continental crust is composed of felsic (rich in feldspars and silica) rocks and the oceanic crust of mafic (rich in magnesium and iron) rocks. The mantle however is composed of peridotite (which is ultramafic meaning it has very high concentrations of the denser magnesium and iron minerals). As such it is much denser than either the mafic or felsic rocks of the crust and the density increases with increasing depth. The crust and solid upper mantle are known together as the lithosphere as they have similar mechanical properties (behaving as a brittle solid) and are separated into the tectonic plates which effectively float on the underlying asthenosphere which is a denser plastic like zone below them the mantle. Ultimately the "floating" of tectonic plates on the upper mantle is due to the density contrast between the materials composing the lithosphere and asthenosphere.


Which layer of the earth has plasticity?

The basic answer is the Mantle, but, really, it's the only very uppermost part of the Mantle that encounters plasticity and convection--when relating to tectonic plate movement, at least. The Asthenosphere is the fluid layer on with plates move across the surface of the earth, being pulled apart (Diverging) or colliding together (Converging). The Asthenosphere is what drives convection and in a very similar way, subduction. Like the person above said, if your teacher/professor hasn't said the word Asthenosphere, then the answer he/she is looking for here is the Mantle, or Upper Mantle. I'd go with Upper Mantle to be safe.


What interior layer allows the earth's rigid outer shell to move?

The Mantle of the Earth is the thickest layer, and while solid, contains elements that cause it to be pliable and flowing due to extreme heat and pressure. It undergoes motions similar to boiling water, known as convection. Convection of the mantle is expressed at the surface through the motions of tectonic plates.


What material would be the most appropriate to represent the asthenosphere?

The material that would be the most appropriate to represent the asthenosphere is Oobleck, corn starch and water mixed together, because it is not liquid nor solid. The asthenosphere is nor liquid or solid. It is something in between but none exactly.

Is the asthenosphere molten?

The asthenosphere is only partially molten with some estimates of around 5 percent.

How are the lithoshphere and asthenosphere similar and how are they different?

The differences and similarities between lithosphere and asthenosphere are as follows. Lithoshphere is made up of rigid rocks flowing above asthenosphere. Asthenosphere has rocks that are more plastic like because they can flow even tho they are still solid rock. The top part of asthenosphere is the same as the lower part of lithosphere, if the top part of asthenosphere cools it then becomes part of lithosphere. Lithosphere and asthenosphere are both made up of the upper part of the mantle on Earth but Lithosphere is also made up of the crust.

How is crust similar to lithosphere?

The Earth's Crust, Lithosphere and Asthenosphere. Crust, the upper layer of the Earth, is not always the same. ... The tectonic plates are made up of Earth's crust and the upper part of the mantle layer underneath. Together the crust and upper mantle are called the lithosphere and they extend about 80 km deep.

Feels as though your floating. Like you don't feel the weight of your own body. No pressure. Similar to floating on your back in water
