A company with a natural monopoly might be the only provider or product or service in an industry or geographic location. Natural monopolies are allowed when a single company can supply a product or service at a lower cost than any potential competitor but are often heavily regulated to protect consumers.
The density gradient model most closely resembles the... urban model.
<h3>What is the density gradient model?</h3>
This model establishes particles are not equally distributed but there are some zones with more or fewer particles. Moreover, particles move from a higher concentration zone to a lower concentration zone.
<h3>What urban model is similar to the gradient model?</h3>
The density gradient model mostly resembles the demographic transition model that explains the density of demographic zones changes over time as more people move to the zone or people leave the zone. This is similar to density gradient because it shows density is not uniform and it evolves.

Group of answer choices.
A. Weather on Earth's surface
B. Rotation of Earth on its axis
C. Metal liquifying in the inner core
D. Revolutions of Earth around the Sun
E. Rock solidifying in the outer mantle
F. Motion of metal in Earth's outer core
Answer:
B. rotation of Earth on its axis.
F. motion of metal in Earth's outer core.
Explanation:
The phenomena which help form Earth’s magnetic field includes;
I. Rotation of Earth on its axis.
Earth rotation can be defined as the amount of time taken by planet earth to complete its spinning movement on its axis.
This ultimately implies that, the rotation of earth refers to the time taken by earth to rotate once on its axis. One spinning movement of the earth on its axis takes approximately 24 hours to complete with respect to the sun.
II. Motion of metal in Earth's outer core.
When planet earth spins on its own axis, the iron found within a liquid outer core moves around which typically gives rise to powerful electrical currents to be generated inside the liquid iron.
Radioactive minerals found in sedimentary rocks are the outcome of the weathering of igneous rocks. Dating the sedimentary rock would only reveal the time in which the magma cooled to form the igneous rock, not the sedimentary.
