If the long-run average total cost curve of an industry is declining at the point where it intersects the industry demand curve, then we can expect that the industry will be a natural monopoly.
<h3>
What is Natural monopoly?</h3>
This is characterized by high infrastructural costs and other barriers which prevent entry into the market. This gives rise to a very few being involved and usually offers no competition as there is a single seller with unique types of goods and services.
This type of monopoly involves sellers having a big size and able to produce the required output for the consumers. This makes them to be self-sufficient and is characterized by the long-run average total cost curve of an industry declining and intersecting the industry demand curve which is the reason why it was chosen as the most appropriate choice.

The theory of plate tectonics cannot be used in explaining: the origin of the Earth's core.
<h3>What is a tectonic plate?</h3>
A tectonic plate is also known as lithospheric plate and it can be defined as an enormous, solid, irregularly shaped rock slab, that comprises two (2) plates:
- Continental plates
- Oceanic plates
<h3>The theory of plate tectonics.</h3>
The theory of plate tectonics states that the solid outer crust of planet Earth (lithosphere) is typically divided into enormous (massive) slabs of solid rock (plates) that move over the asthenosphere, including the upper portion of the mantle.
<h3>The uses of the theory of plate tectonics.</h3>
- It can be used to explain the presence of magnetic anomalies on the ocean floor.
- It can be used to explain the geographical distribution of earthquakes and volcanoes.
- It can be used to explain the presence of glacial deposits in tropical areas.
- It can be used to explain the origin of mountains.
