The student's question lacks an image, so a specific model can't be identified. However, a common model of Earth's interior includes four parts: the crust, mantle, outer core, and inner core. Each of these parts have distinct characteristics and they are made up of different materials.
Unfortunately, I'm not able to identify the specific model of Earth's interior based on your question as it doesn't include an image for me to review. However, I can tell you that commonly used models include the crust, mantle, outer core, and inner core model, based on our current understanding of geology. The crust is the surface layer, followed by the mantle which is the largest part of Earth's interior. Below the mantle are the outer core and the inner core, which are primarily made up of iron and nickel and exhibit different physical properties.

Answer:
Electro-negativity is the tendency of an atom to attract the shared pair of electron in a covalent bonding while forming a molecule.
Explanation:
In a covalent bonding the atoms share the electrons mutually without actually transferring it to one of the atom to gain a stable configuration. In such a case when one atom is more electro-negative than the other then the shared pair of electron gets slightly shifted towards the more electro-negative developing a denser cloud of electrons near the nucleus of that atom which we denote as partial negative () in the superscript.
In water molecules we have a similar case where the oxygen atom is more eletro-negative (value=3.44) than the hydrogen atom (value=2.2). This leads to a higher electron density near the oxygen atom. A part from the shared pairs, the oxygen atom also possesses 2 lone pairs of electrons which tend tp makethe shape a tetrahedron in a 3D structure. This results in molecular shape being bent with an H-O-H angle of 104.5°.

The metric unit of force is Newton or N. The Newton unit is also equal to kilogram per meter per second squared. The Newton name came from the late physicist Isaac Newton. It is also based on the second law of motion.
Answer:
the metric unit of force is N for newton.
Explanation:
B. linear
C. quadratic
D. direct proportion
Answer:
C. quadratic
Explanation:
Linear graphs are straight lines, and direct proportion graphs are lines that pass through the origin.
Inverse proportion graphs have vertical and horizontal asymptotes passing through the origin.
Quadratic graphs are parabolas.
The graph shown is a parabola, or quadratic.
